160 MAUNA LOA. 



Station, and that Lieutenant Budd should join me at the summit. This 

 arrangement became necessary, as the men would now unavoidably 

 be exposed to the cold, and had recruited so much that they could 

 make the trip between the two stations during the day, with loads, 

 sleeping at the upper or lower station. Dr. Pickering made a trip 

 to-day into the crater on the west side, which he found no easy task. 

 He brought back several specimens of lava. The night was clear, 

 but very cold. 



On the 29th we were busy putting up the pendulum apparatus. 

 A short time after noon, Dr. Judd again joined us with the joyful 

 news that the party from the ship had arrived, with sixty days' 

 provisions for as many men. I now felt that through our own 

 perseverance we should succeed in obtaining our wishes, for with 

 this supply we could remain sufficiently long to effect my object in 

 visiting the mountain. 



Dr. Pickering left us to descend the mountain, with the intention 

 of ascending that of Mauna Kea with Mr. Brackenridge. The day 

 was much warmer than we had felt it since reaching the summit. 



The fine weather enabled us to build the wall to enclose the whole 

 encampment, put up the houses and tents, and attend to the observa-

 more than half the men had shoes, and not more than that number 

 were fit for duty, parti}' on that account and lameness, together with 

 mountain-sickness. A supply of shoes, and sandals of raw hide, had 

 been sent for, as the men had already worn out two pair. It was 

 exceedingly provoking to learn that there was much delay in getting 

 these articles and the provisions from the ships ; which arose, as I was 

 informed by letter, in consequence of the refusal of the Rev. Mr. 

 Coan to allow the natives to set out early on Sunday morning : he 

 required the officer to state that he believed our necessities were 

 urgent before he would consent to the natives going. 



The temperature in the shade at noon was 47° ; in the sun, 70° ; 

 and at night it again fell to 20°. 



On the 30th we had another delightful day, and improved it to the 

 best of our ability, by numerous observations. 



The articles from below were now continually arriving. We took 

 advantage of the fine weather to make an excursion to the northeast, 

 for the purpose of seeing if I could effect a communication with the 

 ship by simultaneous signals ; after walking for about two hours, we 

 found that no view down the mountain-side could be had, as the top
