predatory auitaals 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 prodf 
fence. For this purpose bodies of permanent water would be chosen, and of 
these the large lake known as Be-e-lche t-hum-uaz has the best facilities and 
attr:.otions for breeding birds. To fence this would require between three 
and five miles of sheep proof fence and in addition a guard (probably a Sava 
jo Indian) './ould have to be stationed there to keep the fence in repair and 
to watch for tresi)aB8er8. It is not thou^t that the increase in breeding 
birds would be sufficient to warrant the expense necessary for such a pro- 
ject, as there is nothing to indicate that a considerable nurabor of ducks 
would nest here provided conditions were more favorable. 
In studying conditions at these lakes I was interested in noting 
that thoid^ horses dally were wading and feeding in them that 1 saw no in- 
dication that they had disturbed any nests. The damage done lay in the 
keeping down of the marsh vegetation. At Be-o-kho t-hum-ne a forty nests of 
the £ardd Qreve were placed in one colony and a number of Ooots'nests were 
scattered about at random. X saw as many us sixty horses gn.sing In this 
lake at one time standing in water up to their bodies but on ouireful ex- 
amination 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 aninuils though aleet at onoe 
when a human entered the water. 
Waterdogs ( Aaby stoma sp. ) were seoh Long Lake and probably occur 
in all of the large lakes. Frogs (Kana pinions ) 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
