covered with good grass, we reached, on the afternoon of the 3d, the 
Uintah fort, a trading post belonging to "Mr. A. Ro ubideau, on the principal 
fork of the Uintah river. We found the stream nearly as rapid and 
cult as the Lake fork, divided into several channels, which were too broad 
to be bridg ot With the aid of guides from the fort, we succeéded, wit 
very great difficulty, in fording it; and encamped near the fort, which is 
situated a short distance above the junction of Wee branches which make 
the river. 
By an immersion of the 1st satellite, (agreeing , with the result of the 
occultation observed at the Duchesne fork,) the longitude of the post is 109° 
56' 42", the latitude 40° 9 ae? Sp 
It has a motley garrison of Canadian and Spanish engagés and hunters, 
with the usual number of Indian women. We obtained a small supply of 
sugar and coffee, with some dried meat and a cow, which was a very ac- 
ceptable change from the pinoli on which we had subsisted for some weeks 
past. I-strengthened my party at this place by the addition of Auguste 
Archambeau, an excellent voyageur and hunter, helongang to the class of 
Carson and Godey. 
On the morning of the 5th we left the fort™ Ee the Uintah river, and 
continued our road over a broken country, which afforded, peabeleh a rich 
addition to our botanical collection; and, after a march of 2 miles, were 
again checked by another stream, called ‘Ashley? s fork, here we were de- 
tained until noon of the next day. 
mersion of the 2d satellite gave for this place a longitude of 109° 
27° 07" , the latitude by i Soghbatils being 40° 28' 0 
n the afternoon of the next day we succeeded in finding a ford; and, 
after travelling fifteen ales, Uhiartoad high up on the mountain side, where 
we found excellent and abundant Brass, which we had not hitherto seen. 
A new species of elymus, which had a purgative and weakening effect 
upon the animals, had oceurred abundantly since leaving the fort. From 
this point, by observation 7,300 feet above the sea, we hada view of the 
Colorado below, shut up amongst rugged mountains, and which is the re- 
aplent of all the streams we had been crossing since we ney the rim of 
e Great Basin at the head of the Spanish fork. 
0 the 7th we had a pleasant but long day’s ; journe, through beautiful 
little valleys dnd a high mountain country, arriving out evening at the 
verge of a steep and rocky ravine, by which we descended to * Brown’s 
hole.” This is a-place well known to trappers in the country, wer the 
cafions through which the Colorado runs expand into a narrow but pe 
valley, about sixteen miles in length, The river was seyetnt hundred 
most eastern part of the Colorado ; and the latitude of our encampment, 
which was opposite to the remains of an old fort on the left bank of 
river, Was hae 46' betdot and, Py observation, the elevation above the sea
