minutes discovered pools of water in a steep streamwav. Nearby 

 the pools was a magnificent loiilii palm. We camped here, and 

 named the place Loiilii Camp. We collected firewood, made a 

 sleeping place of saplings and palm leaves, ate supper, and slept 

 under a warm and starlit sky. The early part of the night was 

 moonlit. The weather remained ideal for our trip. The eleva- 

 tion of Camp Loulu is 1800 feet. The temperature of tlie pools 

 of water was 60' I"". In the morning we cleaned the litter out 

 of the largest pool, and ])iled up the palm leaves that had proven 

 so useful. We broke camp at 8:30 and climbed the spur, and 

 continued iiiaiika along the main ridge. The main criticism of 

 this ridge trail is the numerous elevations and depressions, that 

 soon prove tedious. ( )therwise, the trail is well cut, and afi'ords 

 many magnificent viev/s, on one hand, across Kaukonalaua Val- 

 ley and, on the other, across Waikakalau, Pearl Harbor. Ewa 

 and the A\ aianae Mountains. 



After 1^4 hours' travel we reached the Army sign above re- 

 ferred to. At this ])oint the ridge becomes somewhat steeper. 

 At 10:40 a. m. we reached the summit, and gazed down into 

 Kahana A^alley, and across the intervening hills towards l\a- 

 neohe 15ay and Mokapu Point. The summit knoll which we had 

 attained has an elevation of 2500 feet ; the air temperature was 

 68- F. ; the soil temperature (4 inches down) was 64 F. The 

 wind velocity was 1420 feet in 2 minutes, or 710 feet ix'r minute. 

 The wind appeared to be of average strength, judging from its 

 "feeling." 



We lunched on the summit, and then followed the trail, wliich 

 leads to the left along the- backljone of the Koolaus, and is plainly 

 marked, "To Kahana," by an Army sign. ( )n the next knoll is 

 another sign, "To the Intake," but this refers to the same trail, 

 and no confusion need be made. The trail continues along the 

 summit for at least a <|narter of a mile, and then turns sliarplv 

 down a prominent ridge that leads precipilouslv down into Ka- 

 hana \'alley. This ridge is very stee]), but the trail is well 

 markerl, and is easily followed. 



At 2:30 we had dropped 2C00 feet, and were at ibe pandanus 

 gnn-e at the foot of llie ridge. This grove is 500 \v(\ abo\e sea 

 level; the ]:)ools of water near it were 6S h". I'pon leaehing the

 as Hccia, and reached I lonojuhi the next morning.
