probably the cause of the horses illness. Four sets of Palmer's and six of Bendire's Thrasher were taken during the day. We saw many flocks of Lark Buntings, Red-tailed and other Hawks, Plumbeous Grasshopper, Green-tailed and Cañon Towhees, Gilded Flickers, Black-throated and some other small Sparrows, [illegible]'s Warbler and an Arizona Hooded Oriole. Will captured a Gila Monster and brought it in triumph to the camp, suspended by a rope. When we got in camp for the night O.W. Howard was nowhere to be seen. He often wandered from the wagon while we were travelling so we thought nothing of it and sat down to supper. Afterward, as it grew late we began to get worried so we lit the lantern and placed it on top of the wagon and Will blew the horn, which can be heard for miles. Late at night Howard came in ragged and hungry. At first he would say nothing as to where he had been, but finally he told us. Early in the afternoon, as he was walking through a grove of mesquite trees, for from the wagon, he had stumbled onto some cattle. Most of them ran, but a young bull charged him and forced him to retreat up a tree, and then kept him there until sun-set, when he left. He then had the luck of finding the wagon in the dark, in a [illegible] country unknown to him, and over ground covered with cactus. After walking a long time he heard the horn and knew then that he was all right Apr. 8. Drove to Tucson, although the horse was so stiff as to be almost unable to travel. Three sets of Bendire's Thrasher and one of Verdin were taken during the day. Saw a pair of Arizona Pyrrhuloxias, Arizona Hooded Orioles,
