predatory animals would doubtless be attracted there.

Any attempt at increasing the breeding waterfowl here would of necessity concern itself with enclosing certain areas in a stock proof fence. For this purpose bodies of permanent water would be chosen, and of these the large lake known as Be-e-khet-hum-nez has the best facilities and attractions for breeding birds. To fence this would require between three and five miles of sheep proof fence and in addition a guard (probably a Navajo Indian) would have to be stationed there to keep the fence in repair and to watch for trespassers. It is not thought that the increase in breeding birds would be sufficient to warrant the expense necessary for such a project, as there is nothing to indicate that a considerable number of ducks would nest here provided conditions were more favorable.

In studying conditions at these lakes I was interested in noting that though horses daily were wading and feeding in them that I saw no indication that they had disturbed any nests. The damage done lay in the keeping down of the marsh vegetation. At [[underline]] Be-e-khet-hum-nez [[/underline]] forty nests of the Eared Grove were placed in one colony and a number of Coots'nests were scattered about at random. I saw as many as sixty horses grazing in this lake at one time standing in water up to their bodies but on careful examination I did not find a single nest that had been overturned or injured, though horsetracks led all through the nesting areas. The birds moreover seem to pay little attention to these feeding animals though alert at once when a human entered the water.

Waterdogs ([[underline]] Ambystoma [[/underline]] sp.) were sean in Long Lake and probably occur in all of the large lakes. Frogs ([[underline]] Rana pipiens [[/underline]]) were common and in some places attained a large size. I saw many tadpoles in the lakes. These animals should thrive as at this season they had no bird enemies and need
