This afternoon we crossed the vide that divides the waters of the Great
Basin from those of the Pacific. This we know from the fact that we
crossed a branch of the Pont Neuf River. At night we encamped by the
Pont Neuf. It is from ten to fifteen yards wide, and deep. We saw some
Snake Indians today. They have plenty of horses, which they offer to
sell. The country before us appears very mountainous. I must cut today's
note short, as it takes both hands to keep off the mosquitoes. Confound
the mosquitoes! Distance, twenty miles.
