After traveling over a rough country till noon, we came to Grease Creek
and encamped on it near Rattlesnake Rock. We stopped about two o'clock
for the purpose of resting and letting our cattle feed, as we had just
come over a portion of the route nearly destitute of grass and water. We
came by one little stream which is known to be poisonous, the water
being strongly impregnated with alkali. We learn by some emigrants since
we passed this stream that a company who were ignorant of the nature of
the water let their horses drink it, and many of them died in
consequence. Distance, fourteen miles.
