Cañon and Green-tailed Towhees. Apr. 9. Remained near Tucson until evening, when we drove several miles beyond and camped near the university. We visited Mr. Herbert Brown and had dinner with him, and he gave us a good deal of information about the country we were going through. Apr. 10. Drove out to a ranch near Ft. Lowell and camped there so as to put the horses in pasture and give them a rest. Ten sets of Palmer's and one of Bendire's Thrasher were taken. Will shot a female Pyrrhuloxia.

They said they saw Cañon Wrens, Scott's Orioles and Townsend's Solitaires. Apr. 12. O.W. Howard and Will collected four sets of Vermilion Flycatchers, two of Bendire's Thrasher, two of Mexican Screech Owl, one of Red-tailed Hawk and one of Cañon Towhee.

The way we went there was no trail; we traveled right up the cañon and had a very rough time of it. Near the mouth of the cañon we saw a pair of
