 the Ilopi country, but that his brother had killed one in the A^^iite 

 Mountains of Arizona. 



Late in October, 1892, the cook of one of the surveying parties, a 

 man who had never lived in the West before and who had not even 

 heard of the elk, but who had shot, skinned, and become thoroughly 

 familiar with the mule deer while with the survey, came to camp and 

 told with much excitement of two huge deer with enormous antlers 

 that he had just seen on San Jose Mountain, Sonora, Mexico. He 

 had started them when too far off for a successful shot, and was 

 unable to overtake them. Soldiers wdio w^ent with this man the next 

 day were quite certain that the tracks were those of elk, and I have 

 no doubt that they were, as the cook gave an accurate account of this 

 {inimal without any earlier knowledge of its existence. I had pre- 

 viously and have subsequently thoroughly explored these mountains 

 without seeing any signs of elk. The two mentioned were possibly 

 migrating to the neighboring Sierra Madre Mountains in Mexico.
