in the direction of Yakima River. This deceived us as to our course, and we went back upon it several times, hoping to find a ridge leading to the north, which we presumed would be in the main divide. this search finally proving useless we camped on the night of March 18, at nearly the same place we had on the night of the 17th. The weather on the 18th was cold and the mountain tops covered with a cold fog, which was sometimes a snow storm. "On the morning of the 19th we broke camp at about 8:30 am. The weather was fine, not a cloud in the sky. We had finally concluded that we must stick to the ridge we were on, and we pushed forward, and had such good luck that at 10:10 A.M. we arrived at the pass, the Aneroid barometer marking the elevation of 3,495 feet. Andy Drury, one of the men, remarked as we looked down upon the slopes of Sunday Creek and Green River, that it was the prettiest pass in the mountains. We remained only a few moments, and then continued our way north, discovering in the course of that and the succeeding day, three other passes. From the most northerly pass, which we found to be on the last pass leading out from the north toward any tributary of Green River, we explored a stream leading into Lake Kitchelos (now Kechelus). We arrived at Lake Kitchelos at 5:15 P.M. on March 21 and the next day at Cabin No. 1, which still stands near the mouth of Cabin Creek. The following day took us to Thorpe's Prairie. "By this time, more provisions had commenced to arrive from Ellensburg, for use in making surveys. As we were then familiar with the country, these provisions were sent through to Tacoma Pass as fast as they arrived, on sleds and on men's backs. We accumulated enough provisions there to commence the surveys on April 1. The party of men, which I had left on Green River near Smay Creek having then arrived the surveys were commenced, and were prosecuted during the season with a large force, several lines being run from Tacoma Pass and from Stampede Pass. "All passes to the north of Stampede Pass were also examined, and sufficient instrumental surveys made to determine their character, with the result that Stampede Pass was
