Jan., 1908 NORTHWESTERN COLORADO BIRD NOTES 19 tudes as far as collecting was concerned, until we got to Yarmany Creek, near McCoy, in the cedar and pinyon belt, at 6,800 feet. Thence we crossed into Egeria Park, and went on to Yampa, 7,700 feet. From here on, as long as we followed the Bear River Valley, we gradually reached lower elevations, until at Snake River, seven miles above its confluence with the Bear, we were at 5,850 feet, in a dry desert country with sage brush and chico in abundance. From here we went ?o Douglas Spring, fifteen miles farther, and in the cedars and pinyohs again at 6,700 feet. We went there especially for the Utah Chipmunk (Eulamias dorsalis utah. ensis), which comes into this portion of the state only. The Colorado range of three other species.of small mammals, namely, Eulamias mz'nimus, Callospermo- philus worlmant', and JVeoloma cinnarnomea, is restricted, so far as at present known, to this northwest corner. These are all pale, arid land forms. From Douglas Spring we back-tracked to the Snake, and then went down it to the Bear River, at Lily P. O., .at Mr. F. C. Barnes' ranch, where we camped twenty-four hours, and then ferried the outfit across the Bear in rowboats: rather a strenuous undertaking, as the wagon had to be unloaded, body and top lifted off, wheels taken off, and the whole thing torn apart generally, and then everything put together again on the other side; but all was taken across safely, and the horses made to swim, which they ?d in good shape. Later in the season we could have forded, but were in too great a hurry to wait for the river to run down. We camped that night among the willows and mosquitos, especially mosquitos. It was a dry drive from Lily to Meeker, 60 miles, only two or three watering places along the road until we got close to the latter place. From Meeker on we usually had plenty of water, sometimes teo much, when it rained. The valleys of the White, Grand and lower Eagle Rivers are quite similar and, what one usually finds in western Colorado, fertile lands, but where not cultivated and irrigated covered with much sagebrush, hills sloping down on either side, with aspens on the lower slopes, and pines or spruces above. For certain reasons I wished to go by way of Brackenridge, and hoped to cross from Red Cliff to Ten Mile Creek, and then it was but a little way to Breckenridge. But we found by inquiry that this road, if not impassable, would be at best a pretty tough proposition. So, instead of taking that route, we drove over Ten- nessee Pass to Leadville, then turned back and crossed Fremont Pass to the Pacific Slope again, thence down the Ten Mile and up the Blue to Breckenridge. And then we crossed the Continental Divide once more at Boreas Pass. The airline distance between Tennessee and Boreas Passes is only about 18 miles; but we trav- eled several times that between them. From Boreas it was down thru the South Park country, and over the Hayden Divide, and then thru the Ute Pass to Colorado Springs and home, on August 12. The life zones traversed covered everything from the Upper Sonoran to the Alpine. During all this time I devoted myself practically exclusively to mammals, and birds were but a side issue, not many being collected. If we had looked more for birds I have no doubt but that this list would be much longer. The early part of the season was cold and stormy; it was not until the end of the first week in June that we had really good settled weather. The migrations seemed late, tho my notes on that subject are not of much value; traveling as we did from the higher to the lower altitudes during the migrating season, we were moving in a contrary direction to the migrants, and usually stopping for only a few days at each place, but little could be told as to the birds' movements. I wish to acknowledge here my appreciation of Mr. Frey's services. Tho his special duties were to look after the team and camp outfit, and to see that we ha4
