creases in size, and is not always fordable. A good trail follows the valley. The 
stream is well supplied with wood, and good grass and water lor camping are 
readily found. 32 $ 
Leaving the Touchet, with an easy ascent the trail passes again to the plains; 
the soil becomes poor and sandy, the grass gives place to the artemisia, and, ap¬ 
proaching Wallah-Wallah, the country is a sandy, wild-sage desert. In this inter¬ 
val is neither wood, water, nor sufficient grass. 19£

This is the sum of the estimated courses. It is probably no greater, and is perhaps a little less, 
than the actually travelled distance. The course plotted and compared with the odometer sur¬ 
vey appears to be about ten miles in excess. Most of the mountain reconnaissance was con¬ 
ducted during thick, snowy weather, with snow-shoes and heavy packs, and under circumstances 
that rendered it impossible to obtain an accurate survey.
