Thursday August 7th. 1806.
It began to rain about midnight and continued with but little 
intermission until 10 A. M. today. the air was cold and 
extreemly unpleasant. we set out early resolving if possible 
to reach the Yelowstone river today which was at the distance 
of 83 ms. from our encampment of the last evening; the currant 
favoured our progress being more rapid than yesterday, the 
men plyed their oars faithfully and we went at a good rate. 
at 8 A. M. we passed the entrance of Marthy's river which 
has changed it's entrance since we passed it last year, falling 
in at preasent about a quarter of a mile lower down. at or just 
below the entrance of this river we meet with the first appearance 
of Coal birnt hills and pumicestone, these appearances 
seem to be coextensive. here it is also that we find the first 
Elm and dwarf cedar on the bluffs, the ash first appears in the 
instance of one solletary tree at the Ash rapid, about the Elk 
rapid and from thence down we occasionally meet with it scattered 
through the bottoms but it is generally small. from 
Marthy's river to Milk river on the N. E. side there is a most 
beautifull level plain country; the soil is much more fertile 
here than above. we overtook the Fieldses at noon. they 
had killed 2 bear and seen 6 others, we saw and fired on two 
from our perogue but killed neither of them. these bear resort 
the river where they lie in wate at the crossing places of 
the game for the Elk and weak cattle; when they procure a 
subject of either they lie by the carcase and keep the wolves 
off untill they devour it. the bear appear to be very abundant 
on this part of the river. we saw a number of buffaloe Elk 
&c. as we passed but did not detain to kill any of them. we 
also saw an unusual flight of white gulls about the size of a 
pigeon with the top of their heads black.

 at 4 P. M. we 
arrived at the entrance of the Yellowstone river. I landed at 
the point and found that Cap
t. Clark had been encamped at this 
place and from appearances had left it about 7 or 8 days. 
I found a paper on a pole at the point which mearly contained 
my name in the hand wrighting of Cap
t. C. we also found the 
remnant of a note which had been attatched to a peace of 
Elk'shorns in the camp; from this fragment I learned that 
game was scarce at the point and musquetoes troublesome 
which were the reasons given for his going on; I also learnt 
that he intended halting a few miles below where he intended 
waiting my arrival.
[38]
 I now wrote a note directed to Colter and 
Collins provided they were behind, ordering them to come on 
without loss of time; this note I wraped in leather and attatched 
to the same pole which Cap
t. C. had planted at the point; this 
being done I instantly reimbarked and decended the river in 
the hope of reaching Cap
t. C's camp before night. about 7 
miles below the point on the S. W. shore I saw some meat 
that had been lately fleased and hung on a pole; I directed 
Serg
t. Ordway to go on shore [and] examine the place; on his 
return he reported that he saw the tracks of two men which 
appeared so resent that he beleived they had been there today, 
the fire he found at the plce was blaizing and appeared to have 
been mended up afresh or within the course of an hour past. 
he found at this place a part of a Chinnook hat which my men 
recognized as the hat of Gibson; from these circumstances we 
concluded that Cap
t. C's camp could not be distant and pursued 
our rout untill dark with the hope of reaching his camp in 
this however we were disappointed and night coming on compelled 
us to encamp on the N. E. shore in the next bottom 
above our encampment of the 23
rd. and 24
th. of April 1805. as 
we came too a herd of buffaloe assembled on the shore of 
which we killed a fat cow.
