AUGUST 13, MONDAY. 



We moved camp to-day, so we were all up bright and early. 

 Before we went M. went to No. i, and we observed the barom- 

 eters to get the height of our base-line. Then M. and Joe 

 started for the new camp with the mules and our utensils, 

 while L. remained in the old camp to make another series of 

 observations. L. then went over, and the new camp was in 

 good shape by night-time. We found our old friends, the 

 mosquitoes, here in large numbers, and with a good prospect 



ot ilieir saving all night. 



AUGUST 14, TUESDAY. 



M. and Joe started early for the ridge. Finished Nos. 8, 

 12, and 13, and joined in their triangles the point of No. u. 

 (This is a very precipitous point in the centre of the valley 

 which we called Santa Anna Mount.) The scenery was re- 

 markably fine, overlooking the upper basin of the East Branch 

 on one side and the valley of Black's Fork on the other. 

 They were troubled by the cold, the snow, and rain, and the 

 electricity, which affected the transit, sung and hissed in the 

 monument, gave repeated and severe shocks to the operator, 

 and at one time ran in a stream from the barometer to the 

 ground. L. was found alive, but battling with the mosqui- 

 toes ; all that was to be seen of his face or body was a ring 

 around the eyes, .left for observing purposes. M. hurt his 

 knee badly in the timber. 



AUGUST 15, WEDiNESDAY. 



L. and Joe started off this morning, while M. did up some 

 camp chores, and made corresponding observations. Points 

 14, 15, 1 6, and 17 were fixed, establishing some very impor- 

 tant stations in the valley one on the transverse axis of the 

 range. They were also troubled by electricity, and kept from 

 work for some time by it. 



AUGUST 16, THURSDAY. 



M. and Joe started up the eastern ridge to point No. 10; 

 but on arriving there found it impossible to use the transit 

 on account of the electricity, so putting it up in its case they 

 went to the next peak in line and built a monument, and were 

 then forced to retire in a furious hail-storm. To-day, we may 

 say here by way of parenthesis, our troubles began. We 

 found this morning one of our mules (the best one at that)
