Odocoileus hemionus californicus (Caton). 
California Mule Deer. 
Deer are becoming scarce in this region where a few years 
ago, from all accounts, they were plentiful. The steadily and 
‘apidly increasing invasion of hunters each season is of course 
the cause of this; for their original enemies, the mountain lions 
and coyotes, have almost disappeared in their domain. More 
stringent hunting laws, and especially the enforcement of what- 
ever ones are on the statutes, will go a long way toward saving 
the deer from complete extermination. A five-year close season 
would be the best means, if adequately enforced. In all our 
field-work not more than half a dozen were seen each summer. 
I personally saw but three bucks in all of the three seasons. 
Does were usually seen down along the upper Santa Ana and 
adjacent cienagas, while the bucks were high on the ridges. I 
saw no signs higher than Dry lake, 9000 feet altitude; and the 
deer occurred down into the Upper Sonoran brush belt, the latter 
affording better cover than the open pine woods higher up. I 
had no rifle and never even shot at a deer, but the bland curiosity 
displayed by some of those ‘‘jumped,’’ which led them to return

over a ridge and look at me, like tame deer in the ‘‘zoo,’’ con- 
vinced me that there would be no sport, for me, at least, in 
shooting one. 
Sciurus griseus anthonyi (Mearns). Anthony Gray Squirrel. 
The gray squirrel was a common species in most parts of the 
Transition zone. I failed to find it either above or below this 
zone, and found it but sparingly in the most arid parts of it. 
It was common along the upper Santa Ana aboye the 5300-foot 
contour line. We saw young early in July in Lost ereek canon. 
In the lower Fish creek canon one could hardly fail to note one 
or more in an hour’s walk. At our South Fork camp, in 1906, 
the group of Jeffrey pines which shaded the site was loaded with 
large green cones. Before we had been there long the contin- 
ually falling cone-seales and drops of fresh pitch told us of activ- 
ities overhead. This annoyance was replaced by a desire for 
immediate action on our part when one of the three-pound green
