Mānoa Arboretum

Hahai nō ka ua i ka ululāʻau
The Rain Follows the Forest

“Not enough rain and not enough water in the streams are great evils”.

“It appears to me to be unnecessary to again go deeply into the theory of the relation between forests and rainfall when all intelligent and observing people admit that the decrease or increase of rainfall goes pari passu (‘hand-in-hand’) with the decrease or increase of the forests.”

“The forest, which not only produces rain, but also retains the rainwater, holding it among its leaves and branches, its undergrowth, its myriads of roots and rootlets and its fallen debris, letting the rainwater trickle down slowly to the water streams and keeping them supplied for a long time”.

“(T)hat forest is not there. Rain pours down, the water rushes in torrents through the streams to the sea and soon after everything is dry again.” (Gjerdrum to HSPA, 1897)

“The ultimate success of forestry in Hawaiʻi depends on the continued cooperation of individuals and private corporations with the Territorial Government.” (Board of Agriculture and Forestry, December 31, 1907)

In the early-1900s, Mānoa Valley’s lower slopes were stripped of their native vegetation by excessive agricultural cultivation and the overgrazing of cattle.

Without healthy forest cover, rainwater flowed to the ocean rather than recharging the ground water table, Hawaiʻi’s primary source of drinking water. This loss was of special concern to the Hawaiian Sugar Planters’ Association (HSPA,) because sugar required great quantities of water.

In 1918, HSPA established Mānoa Arboretum in order to develop methods of watershed restoration, test tree species for reforestation and collect plants of economic value.

They put Dr Harold L Lyon, a young botanist from Minnesota, in charge of 124-acres at the back of Mānoa Valley. He was, at the same time, superintendent of the Territory’s Department of Botany and Forestation.

The site lies in the ʻili (land division) of Haukulu and ʻAihualama, in Mānoa. Several man-made features, including stone platforms, loʻi and the occurrence of many Polynesian-introduced plants note early use of the site.

One of Dr Lyon’s tasks at the arboretum was to identify trees suitable for rebuilding watersheds. Lyon observed that the adverse conditions of soil created from volcanic rock erosion appeared to affect the growth, survival and eventual death of many tree species.

He also noted that native plants did not thrive in areas that were previously trampled by cattle and other animals. The experiment station’s goal was to find trees that not only could survive in soil containing volcanic rock components, but also would comprise efficient water-conserving forests.

Mānoa Arboretum was a test site to evaluate trees that could be used for reforestation throughout the islands, and to test sugarcane seedlings. The test site became the basis of the Mānoa Arboretum.

Tree-planting was a coordinated effort involving Lyon, HSPA and Territorial Forestry under the direction of Ralph Sheldon Hosmer, the Territorial Forester. The early foresters planted many types of trees on an experimental basis, but concluded that native species were of limited utility and turned largely to introduced species for large-scale reforestation efforts. (Woodcock)

Lyon concluded that healthy forests should be preserved, that heavily damaged native forests could not recover on their own, and that damaged watersheds could be restored with introduced plants. Planting began in 1920, and was essentially completed by 1945.

“As an influential board member on the Agriculture and Forestry Commission, Harold Lyon succeeded in persuading the Territorial Commission to import seed of a vast number of alien tree species. … nearly 1,000 alien species were outplanted in Hawaiʻi forest reserves.” (Mueller-Dombois)

Various trees and plants were imported from diverse areas of the world including Madagascar, Australia, India, Brazil, the Malay states, China, the Philippines, southern Europe, the East Indies, the West Indies, New Zealand, Central America and South Africa. Trees that successfully survived the Mānoa Valley soil conditions and promoted water conservation were then widely planted throughout the arboretum

Eucalyptus species, silk oak, paperbark and ironwood were the most frequently planted trees due to their fast growth and their resistance to adverse environmental conditions. However, these very qualities, as well as their ability to seed profusely, would lead to some species such as tropical ash and albizia. (Iwashita)

The number of trees planted rose to many millions by the 1930s, when the Civilian Conservation Corps (CCC) was available for planting. From 1935 to 1941, with the help of the CCC, an average of close to two-million trees were planted per year in the forest reserves.

Lyon envisioned the plantations as a buffer zone that would be established between the remaining native forests and the lower-elevation agricultural lands to protect the native forests and perform the functions (maintaining input of water to aquifers.)

This large-scale attempt to engineer nature was probably the largest environmental project ever carried out in the islands. Forestry introductions have been a significant contributor to Hawaiʻi’s alien-species crisis, with many of these tree species now problem invasive species. (Woodcock)

In his 1949 annual report to the HSPA entitled, ‘What is to be the fate of the arboretum?,’ Lyon declared the Mānoa Arboretum’s mission to test new plant introductions to be essentially complete; he believed that the HSPA should not remain the arboretum’s custodian.

On July 1, 1953, HSPA conveyed the Mānoa Arboretum to the Board of Regents of the University of Hawaiʻi. The regents were individually entrusted with the fiduciary duty of maintaining the arboretum. In 1962, the Board of Regents transferred the arboretum to the University of Hawaiʻi.

Dr. Lyon remained with the arboretum as its first director under the regents’ and university’s stewardship. After Dr. Lyon’s death in 1957, an advisory committee directed the arboretum until 1961, when Dr. George Gillette assumed the directorship on a part-time basis.

When Dr. Lyon died, the Board of Regents renamed the facility the Harold L. Lyon Arboretum (Lyon Arboretum) in honor of the man so closely associated with its growth and fruition.

In the early years, eight cottages were built on the arboretum site for staff use. The cottages were given alphabetical designations, beginning with cottage “A” at the foot of the hill leading into the arboretum site and ending with cottage “H” at the top of the hill. Lands surrounding the cottages were planted with sugar cane. Dr. Lyon also erected an orchid greenhouse between cottages “F” and “G,” which is still used today.

Cottage “H” was expanded over time and is now the main center of the Harold L. Lyon Arboretum, housing offices, a reception area, an educational office, and a book and gift shop.

Forestry, Forest Reserves, Watershed Partnerships, invasive species and related water and habitat concerns were very much a part of daily activities when I was at DLNR.

Today, I am honored and proud to serve as a director on the Hawaiʻi Forest Institute, an organization dedicated to promote the health and productivity of Hawaiʻi’s forests, through forest restoration, educational programs, information dissemination and support for scientific research.

Niuhelewai

The ahupua‘a of Kapālama has two streams, the Kapālama and the Niuhelewai (“coconut going (in) water”). They merge and extend through the central fertile area also called Niuhelewai. This area drained into a pond called Kūwili II.

John Papa ‘Ī‘ī described the appearance of the trail (around the year 1810) from Nuʻuanu to Moanalua through Kapālama: “When the trail reached a certain bridge, it began going along the banks of taro patches, up to the other side of Kapālama, to the plain of Kaiwiʻula …”

While somewhat general, the ‘Ī‘ī account supports that of von Kotzebue in relating an abundance of lo‘i where the main trail crossed Nuʻuanu Stream, a relatively uncultivated plain as the trail traversed Kapālama and Kaiwi‘ula, and then more lo‘i on Kalihi Stream (Cultural Surveys)

“(O)n the south and west, spread the plain of Honolulu, having its fish-ponds and salt making pools along the sea-shore, the village and fort between u and the harbor, and the valley stretching a few miles north into the interior, which presented its scattered habitation and numerous beds of kalo in its various stages of growth …”

“Through this valley, several streams descending from the mountains in the interior, wind their way, some six or seven miles watering and overflowing by means of numerous artificial canal the bottom of kalo patches, and then, by one mouth, fall into the peaceful harbor.” (Hiram Bingham)

Haumea, the goddess of childbirth, had a home at Niuhelewai in Kapālama; Haumea, sometimes identified with Papa, or the Earth mother, was a female akua that with ‘great source of female fertility.’ She married Wākea and later married Hāloa, her husband’s son by his own daughter Hoʻohokukalani. She is considered the mother of Pele and of Pele’s siblings

In chants she is called Haumea ‘of mysterious forms, of eightfold forms, of four hundred thousand forms.’ One of her commonly known forms, however, is the breadfruit tree. There is no single word haumea in Hawaiian, but hau can mean “a ruler” and mea can mean “reddish (like red earth). (King)

Niuhelewai was the location for a famous battle between Kahekili’s forces and the O‘ahu ruling chief Kahahana.

At the time of Captain Cook’s arrival (1778,) the Hawaiian Islands were divided into four kingdoms: (1) the island of Hawaiʻi under the rule of Kalaniʻōpuʻu, who also had possession of the Hāna district of east Maui; (2) Maui (except the Hāna district,) Molokaʻi, Lānaʻi and Kahoʻolawe, ruled by Kahekili; (3) Oʻahu, under the rule of Kahahana; and (4) Kauaʻi and Niʻihau, Kamakahelei was ruler.

Kahahana was high-born and royally-connected. His father was Elani, one of the highest nobles in the ʻEwa district on Oʻahu, a descendant of the ancient chiefs of Līhuʻe. While still a child, Kahahana was sent to Maui to live with Kahekili. (Fornander)

Then, Oʻahu chiefs selected Kahahana to be their leader (this was the second island chief to be elected to rule Oʻahu; the first was Māʻilikūkahi, who was his ancestor.)

Kahahana left Maui and ruled Oʻahu. When war broke out between Kalaniʻōpuʻu of Hawaiʻi Island and Kahekili in 1779, Kahahana had come to the aid of Kahekili. Later, things soured.

“At that time Kahekili was plotting for the downfall of Kahahana and the seizure of Oʻahu and Molokaʻi, and the queen of Kauaʻi was disposed to assist him in these enterprises.” (Kalākaua)

In the beginning of 1783, Kahekili sought to add Oʻahu under his control. Kahekili invaded Oʻahu and Kahahana, landing at Waikīkī and dividing his forces in three columns (Kahekili’s forces marched from Waikīkī by Pūowaina (Punchbowl,) Pauoa and Kapena to battle Kahahana and his warriors.)

Kahahana’s army was routed, and he and his wife fled to the mountains. For nearly two years or more they wandered over the mountains, secretly aided, fed and clothed by his supporters, who commiserated the misfortunes of their former king. Kahahana was later killed.

Some of the remaining Oʻahu chiefs sought revenge and devised a wide-spread conspiracy against Kahekili and the Maui chiefs. The plan was to kill the Maui chiefs on the same night in the different districts.

However, before they could carry out their plan, Kalanikūpule found out their intentions and informed his father, Kahekili. Messengers were sent to warn the other chiefs, who overcame the conspirators and killed them. (Apparently the messenger to warn the chiefs in Waialua was too late and the Maui chiefs there were killed.)

Gathering his forces together, Kahekili overran the districts of Kona and ʻEwa, and a war of extermination ensued. This event was called Kapoluku – “the night of slaughter.” (Newell)

Men, women, and children were massacred; all the Oahu chiefs were killed and the chiefesses tortured. (Kamakau) The waters of the Niuhelewai stream were turned back, the stream being dammed by the corpses. (Fornander)

Kalaikoa, one of the Maui chiefs, scraped and cleaned the bones of the slain and built a house for himself entirely from the skeletons of the slaughtered situated at Lapakea in Moanalua. The skulls of slain Oʻahu chiefs adorned the doorways of the house. The house was called “Kauwalua.” (Lots of information here is from Fornander, Kamakau and Cultural Surveys.)

Two Cummins Schools – Now None

Today, Washington Intermediate and Liholiho Elementary serve their respective communities in Pawaʻa and Kaimuki.

But they weren’t known as such (at least by conflicting claims of the City and Territory.) Depending on who you talked to, each was known as Cummins School, named after John Adams Kuakini Cummins.

Cummins, born March 17, 1835 in Honolulu, was a namesake of Hawaii Island Governor John Adams Kuakini (1789–1844 – Queen Ka‘ahumanu’s brother,) who had taken the name of John Quincy Adams when Americans were settling on the Islands in the 1820s.

In the 1840s, Cummins’ father (Thomas Jefferson Cummins (1802–1885)) first developed a cattle ranch and horse ranch on the windward side. By the 1880s, facing diminishing, John began to grow sugar cane in place of cattle. That plantation was known as the Waimanalo Sugar Company.

On June 17, 1890, Cummins became Minister of Foreign Affairs in King Kalākaua’s cabinet. When Kalākaua died and Queen Liliʻuokalani came to the throne in early 1891, she replaced all the ministers.

Cummins resigned February 25, 1891. He was replaced by Samuel Parker who was another part-Hawaiian. (There is a photo of both Cummins and Parker serving as kāhili bearers for Keʻelikōlani (Princess Ruth.))

Cummins supported the constitutional monarchy; after the overthrow in early 1893, Liliʻuokalani asked Cummins to travel to the continent to lobby for its restoration. Cummins died March 21, 1913. His great-grandson was Mayor Neal Blaisdell.

OK, back to the schools … here’s how the confusion, and correction, came about:

Both schools were built the same year, 1926.

Back then, the Territorial Department of Public Instruction (now the DOE) provided the instruction in schools and the City, through the Board of Supervisors (now the County Council,) owned the school properties and buildings.

The Department named the Pawaʻa school first – consistent with their policy, they called it Washington Intermediate (it was the first Intermediate school on O‘ahu.)

However, the Board of Supervisors wanted the school to be called Cummins Intermediate. (The Pawaʻa school is built on land that was formerly owned by Cummins and the City wanted to recognize that.)

Actually, before Cummins owned it, Anthony D Allen (a former slave from the continent) had his home there (including about a dozen other houses.) Several references note his property as a “resort;” “… it is a favourite resort of the more respectable of the seamen who visit Honoruru. …” (Reverend Charles Stewart) It may have been Waikiki’s first hotel.

Allen entertained often and made his property available for special occasions. “King (Kauikeaouli – Kamehameha III) had a Grand Dinner at AD Allen’s. The company came up at sunset. Music played very late.” (Reynolds – Scruggs, HJH)

Missionaries Hiram and Sybil Bingham (my great-great-great grandparents) also visited. Sybil noted in her diary, “He set upon the table decanters and glasses with wine and brandy to refresh us”. They ended dinner “with wine and melons”.

OK, back to the new schools … as a compromise to the naming issue, the Department kept the Washington name for the Pawaʻa school and named the new elementary school in Kaimuki, Cummins School.

That didn’t go over very well with the City and County and they refused to recognize the name – and they continued to call the Pawaʻa school Cummins Junior High School, while the Territory called that school Washington Intermediate.

The Kaimuki school was referred to by the City and County as Liholiho School, and the Territorial Department of Public Instruction called it Cummins School.

To further add to the confusion, the PTA for the Kaimuki school was known as the ‘Liholiho Parent Teacher Association of Cummins School.’

Effectively, there were two Cummins Schools, depending on who you talked to. The issue was resolved (somewhat) in 1935.

“Ending a longstanding uncertainty, the public school at Maunaloa and 9th avenues, Kaimuki, which has been variously known as Cummins School and Liholiho School since its establishment several years ago, will henceforth be known as Liholiho School.”

For some, the Pawaʻa school on King Street continued to be called Cummins Junior High School, and the name appeared over its door, although the education department clung to its policy of naming Intermediate schools after American Presidents or members of the Hawaiian Royal family, and called it Washington.

Reconstruction of the buildings at Pawaʻa seemed to settle the matter and the school is now referred to as Washington Middle School; and, Liholiho Elementary continues to operate in Kaimuki.

Neither, now, is referred to as Cummins. (Lots of information here is from Star Bulletin, June 3, 1935.)

The Pali

In the early nineteenth century there were three routes from Honolulu to Windward Oʻahu: around the island by canoe; through Kalihi Valley and over the pali by ropes and ladders; and over Nuʻuanu Pali, the easiest, quickest and most direct route.

The first foreigner to descend the Pali and record his trip was Hiram Bingham (my great-great-great grandfather.) His zeal for spreading the word of God led him to take a group of missionaries over the Pali to the Koʻolaupoko area in 1821.

The current Pali Highway is actually the third roadway to be built there. A large portion of the highway was built over the ancient Hawaiian foot paths that traversed the famous Pali pass.

In 1845 the first road was built over the Nuʻuanu Pali to connect Windward Oʻahu with Honolulu. It was jointly financed by the government and sugar planters who wanted easy access to the fertile lands on the windward side of Oʻahu. Kamehameha III and two of his attendants were the first to cross on horseback.

A legislative appropriation in 1857 facilitated road improvements that allowed the passage of carriages. The Rev. E. Corwin and Dr. G. P. Judd were the first to descend in this manner on September 12, 1861.

In 1897, Johnny Wilson and fellow Stanford student Louis Whitehouse won the bid to expand and construct a ‘carriage road’ over the Pali. Ground was broken on May 26, 1897 and the road was opened for carriages on January 19, 1898.

When the current Pali Highway and its tunnels opened (1959,) the original roadway up and over the Pali was closed and is now used by hikers.

I am old enough to have traveled (and young enough to still remember traveling) on the Old Pali Road over the Pali before the tunnels were built.

Living on the windward side and initially going to school and then in later years working in Honolulu, there was always a satisfaction of going through the tunnels and heading home, leaving the rest of the world behind you.

Folklore holds that you should never carry pork over Old Pali Highway, especially at night. Motorists reported that their cars mysteriously stopped and would not start until the pork was removed from the car.

The stories vary, but are rooted in the legendary relationship between fire goddess Pele and the demigod Kamapuaʻa (a half-man, half-pig.) The two agreed not to visit each other.

If one takes pork over the Pali, you are bringing a physical form of Kamapuaʻa into Pele’s territory and breaking their agreement. Some versions note a white dog appears when your car stalls.

The Pali was the site of the Battle of Nuʻuanu, one of the bloodiest battles in Hawaiian history, in which Kamehameha I conquered Kalanikupule of Oʻahu, bringing it under his rule.

In 1795 Kamehameha sailed from his home island of Hawaiʻi with an army of thousands of warriors, including a handful of non-Hawaiian foreigners.

The war apparently ends with some of Kalanikupule’s warriors pushed/jumping off the Pali. When the Pali Highway was being built, excavators counted approximately 800-skulls, believed to be the remains of the warriors who were defeated by Kamehameha.

If you’re driving up the Pali Highway from town you can see two notches cut in the narrow ridgeline. The notches are man-made. Many believe they were cannon emplacements, used especially during the Battle of Nuʻuanu between Oʻahu’s Kalanikupule and Hawaiʻi Island’s Kamehameha.

However, per Herb Kane, “Kalanikupule had some arms bigger than muskets, but they were probably just swivel guns. Besides, the Battle of Nu‘uanu Pali started as a skirmish by Diamond Head, and no one knew where the battle would end up. Kalanikupule could not have planned it that way.”

“Hawaiians, like everyone else, understood the value of high ground. These are certainly (pre-Cook) lookout stations, and that’s why you see them all over the islands – if you look out for them.”

Lili‘uokalani used to visit friends at their estate in Maunawili. She and her brother King David Kalākaua were regular guests and attended parties or simply came there to rest.

Guests, when leaving the home, would walk between two parallel rows of royal palms, farewells would be exchanged; then they would ride away on horseback or in their carriages.

On one trip, when leaving, Liliʻu witnessed a particularly affectionate farewell between a gentleman in her party and a lovely young girl from Maunawili.

As they rode up the Pali and into the swirling winds, she started to hum a melody weaving words into a romantic song. The Queen continued to hum and completed her song as they rode the winding trail down the valley back to Honolulu.

She put her words to music and as a result of that 1878 visit, she wrote “Aloha ‘Oe.”

The melody may have been derived from Croatian folk song (Subotika region) Sedi Mara Na Kamen Studencu (Girl On The Rock,) in 1857 published in Philadelphia by Charles Crozat Converse as The Rock Beside The Sea.

Aloha ʻOe was first introduced in America in 1883 by the Royal Hawaiian Band with Heinrich (Henry) Berger conducting.

(When Liliʻuokalani was imprisoned, Johnny Wilson’s mother Eveline (Townsend) Wilson was her lady in waiting. During her imprisonment, Queen Liliʻuokalani was denied any visitors – but Johnny would bring newspapers hidden in flowers from the Queen’s garden.)

(Reportedly, Liliʻuokalani’s famous song Kuʻu Pua I Paoakalani (written while imprisoned,) was dedicated to Wilson (it speaks of the flowers at her Waikiki home, Paoakalani.))

(The other early set of Koʻolau tunnels, first known as the Kalihi Tunnel (competed in 1960) were named in honor of Johnny Wilson. The H-3 tunnels are named after Tetsuo (Tets) Harano, a former DOT Highways administrator.)

Waiāhole Water Company

Oʻahu Sugar Company constructed the Waiāhole Ditch System to transport, by gravity, water from the northeastern side of the Koʻolau Range. The Waiāhole Ditch collection and delivery system was constructed during 1913-1916.

The general plan or scheme of development adopted for the Waiāhole Water Co. was that recommended by Mr. J. B. Lippincott, C. E., who made an exhaustive study of the project, going fully into the past history and study already made by Mr. J. Jorgensen and other parties, and reported to the Board of Directors of the Oahu Sugar Co., Ltd., under date of August 19, 1911.

The general plan provided for collecting the water from the many streams and gulches on the windward side of Oahu by means of tunnels through the ridges or spurs, and conveying the water, after collecting, through the mountain in the main tunnel to the leeward side of the island, thence by tunnels, ditches and pipes, to the upper levels of Oahu Sugar Plantation.

The tunnels connect up the various streams on the North side, and take in the water at the adits in the gulches. There are 27 of these tunnels on the North side, varying in length from 280 feet to 2,332 feet, the aggregate length of the North side tunnels being 24,621 feet, or 4.66 miles, being in reality one continuous tunnel.

The maximum elevation at which water is taken into the tunnel is 790 feet above sea level, and the grade or slope of the North side tunnels is 1.3 feet per thousand. The length of the main tunnel through the Koʻolau Ridge is 14,567 feet, or 2.76 miles, the grade or slope being 2.0 feet per thousand.

The elevation of the North portal of the main tunnel is 752 feet above sea level, and at the South portal 724 feet. The size of tunnel section is approximately 7 feet wide and 7 feet high, but in many places the section is larger, due to the uneven cleavage of the rock, and the fact that certain portions are unlined.

From the tunnel, the water is then conveyed by means of cement-lined open ditches, elevated concrete ditches, four steel pipes, and three redwood pipes. It is delivered to the upper boundary of Oahu plantation at an elevation of 650 feet through several distributaries, and by the main ditch, which reaches this elevation at the boundary of Honouliuli.

The water is also delivered into numerous reservoirs, especially at night, when irrigating the cane fields is inconvenient. One of the larger reservoirs, on the line of the Waikakalaua storm water ditch, has long been in use. It is called Five Finger Reservoir. Its elevation was a determining factor in establishing the grade elevation of the Waiāhole conduit.

When the work was undertaken, the time of completion was considered an important element, and Mr. Bishop’s organization was planned to secure the most expeditious execution of the project. The General Superintendent of Construction, Mr. Albert Andrew Wilson, who was in direct charge of all the constructing work.

At the beginning of the tunnel work, three shifts of eight hours each were kept going. This was continued until the large amount of water coming into the tunnel, at North heading, became troublesome, and on account of the hardship on the men, working for eight hours in the cold water, it became necessary to cut the shifts down to six hours each, so that four shifts per day were employed for this heading.

The temperature of the water in the tunnel was approximately 66° F., or about 8° colder than the artesian water in Honolulu, or, roughly, about 1° for each 100 feet of elevation.

Camps were established and sanitary conveniences were built to comply with the requirements of the Board of Health. No serious sickness, such as typhoid fever, gave any trouble.

Special tribute should be paid to the Japanese tunnel men, without whom the excellent progress made on the tunnel would have been impossible.

These “professional” tunnel men, as they call themselves, prefer this work to any other, and they apparently take delight in the hardships incident to the work, the exposure to the cold water, and the risk in handling explosives.

They were on the job all the time and never failed to deliver the goods in situations in which white men or native Hawaiians would have been physically impossible. Most of the drilling and mucking was done by these tunnel men as subcontractors – a bonus being given for rapid work, which sharpened their interest and never failed to give results.

While it was suspected at the outset that considerable water might be encountered in the main bore through the mountain, it was not anticipated at the beginning that enough water would be developed to materially interfere with the progress of the excavation.

This hope was not realized, however, for the main bore had proceeded only about 200 feet from the North portal when water to the extent of two million gallons daily was developed—this on breaking through the first dyke.

These dykes are hard, impervious strata of rock lying approximately at an angle of 45° to the tunnel axis, and nearly vertical, and they occur at intervals of varying length. Between the dykes was the porous water-bearing rock, thoroughly saturated, and with the water pent up between the dykes often under considerable pressure.

When a dyke was penetrated, the water would spout out from the drill holes and would gush forth from the openings blasted in the headings. As the work progressed, the water increased in quantity and the difficulty of the work was enormously greater on account of the water.

The texture and hardness of the rock varied considerably— some of it being particularly soft and porous and much of it hard and flinty—particularly at the dykes. The dykes varied in thickness from 14 feet down to about 4 feet, all composed of very hard, close-grained rock which was apparently waterproof.

From the South portal the progress was rapid, often as high as 630 feet per month, or about 21 feet per day on an average, notwithstanding the long haul, which at the last was over two miles.

Eighty-percent of the length of the main tunnel was driven from the South portal, and 20% of the length was driven from the North portal, the difference in these proportions from the two headings being due to the presence of water at a much earlier stage in the North heading. Had there been no water to contend with, the length driven from each heading would have been approximately the same.

This system of tunnels is essentially a closed-conduit system, that is, the flow is entirely through closed tunnels, not subject to interruption by freshets or washouts or from rubbish or wash from the mountain streams, the intakes being so built as to admit only water as free from rubbish as practicable.

Only at three points in the tunnel system—and these are on the South side, one of which is a gaging station—does the water flow in open channels for an aggregate length of 160 feet.

It is intended to use the reservoirs so far as possible to take care of the water flowing at night, so as to utilize the conduit to its fullest capacity.

The Waiāhole Water Co. has taken over from the Oahu Sugar Co. The water delivered by the Waiāhole System is chiefly used on newly planted cane on land above the lift of the pumps. During construction the water developed in the main tunnel near the South portal was at times utilized for irrigation.

On May 27, 1916, with Mr. H. Olstad as Superintendent, continuous operation of the project was begun. (This post is from portions of a paper read by Chas H Kluegel before the Hawaiian Engineering Association, published in Thrum, 1916)
