This was Surprise Valley, into which a good pass was found, with grass and water plenty, in the

Their horses had worn out their shoes on the rocks of Klamath land ; the sandy desert that lay before them beyond the borders of Surprise Valley seemed to stretch interminably, with no indication or water or grans as far as the eye could see, and unbroken except by rocky ridges; and the prospect for the future looked gloomy. Eut pressing on to the^ close of the day over sand, gravel, and rock, at evening a little spring was most unexpectedly found.

It was about twenty miles in length. A stream ran through it in places under overhanging cliffs. After examining this strange
