night emersions of the second, pire and fourth satellites of Jupiter, with 
observations for time and latitu 
Septer —The morning was 48 clear, with a light air from the north, 
and the thermometer at sunrise at 45°.5. At 3 in the morning, Basil 
was sent back with several men and horses for the boat, which, in a direct 
course aeross the flats, was not 10 miles distant ; and in the mean time there - 
was a pretty spot’of grass here for the animals. The ground was so low 
that we could not get high enough to see across the river, on account of the 
willows ; but we were evidently i in the vicinity of the lake, and the water - 
fowl made this morning a-noise like thunder. ° A pelican (pelecanus ono-. 
crotalus ) was killed as rhe passed by, and many geese and ducks flew over: 
the camp.- .On the dry salt marsh ‘here, i is scarce any yori plant than 
salicornia herbacea. 
In the afternoon the men returned with the boat, bringing with them a. 
small quantity of roots, and some meat, which the ‘Indians had told them 
ar meat. 
Dantseding the river for about three miles in the afternoon, we found a- 
bar to any further sy beebpade b in that direction—the stream being spread out 
in several branches, and covering the low grounds with water, where 
miry nature of the bottom did not permit any further advance. We were 
evidently on the border of the lake, although the rushes and canes which. 
covered the marshes prevented any view ; ‘and we accordingly encamped. 
at the little deta which forms the mouth of Bear river; a long arm of the 
lake stretching up to the north between us and the opposite mountains. 
The river was bordered with a fringe of willows and canes, among which 
were interspersed a few plants; and’scattered about on the marsh was a 
species of uniola, closely allied to U. spiéata of our sea coast. The whole: 
morass was animated with multitudes of water fowl, which appeared to be: 
very Sete for the space of a mile round about At the sound of a gun,. 
with a noise like distant thunder. Several of the people waded out into 
the marshes, and we had to-night a delicious supper of ducks, geese, 
over. 
Although the moon was bright, the night was otherwise favorable ; iid 
re obtained this evening an emersion of the first satellite, with the usual ob-. 
rvations. A mean result, depending on various observations made during - 
our aay in the neighborhood, places the mouth of the river in longitude: 
112° 19’ 30” west from Greenwich; latitude 44° 30’ 99". and, according 
to the barometer, in elevation 4, 200 feet above the gulf of Mexic o. The 
night was clear, with considerable dew, which I had remarked every night 
since the first of September. The next morning, while we were preparing 
to start, Carson rode into the camp with flour and a few other articles of 
light provision, sufficient for two or three days—a scanty but very accepta- 
pe su ply. Mr. Fitzpatrick had not yet arrived, and provisions were very © 
é, and ditlicult to be had at Fort Hall, which had been n entirely ex-. 
Neustee by the necessities of the emigrants. He brought me also a letter 
from Mr. Dwight, who, in company with several emigrants, had ceaeleas 4 
that place in advance of Mr. Fitzpatrick, and was about couleur is 
journey to Vancouver. 
_ Returning about five miles up the river, we were oceupied until 
unset in crossing to the left bank—the stream, which in the ia Roe ak 
miles of i ea —. is very much narrower than above, being very deep im- 
ately e banks ; and we had great difficulty é in ee animals.
