January 6: The snares yielded no example of L. diasi. While thatch¬ 
ing for these animals last night, a L. veracrueis came hopping out into 
ail open spot by a dens© brush patch and I secured him. 
Taking my horse, I rode up the mountain to about timberline where I 
took a view of the mountain, *he smoke is very apparent when the weather 
~r 
is calm now, Proa the base cf the peak of Popocatepetl I crossed the 
divide to the northwest toward Istaccihuatl. The intervening country 
ranges from 12,200 feet at its lowest part up to 13,500 feet at bases 
of the mountains. It is in the farm of a rolling plain draining to the 
HE and 5¥, and is covered with bunch grass with scattered trees along 
the sides of small canons and sheltered hill slopes, but it is mainly 
open and resembles a rolling prairie. The old highway from Tlaxcala 
and Puebla crosses here. Getting near the south end of Iztaeoihuatl, 
it was evident that this end of the mountain once gave off 5 large 
glaciersi one leading dorm toward the plain of Puebla where its drain¬ 
age flayed, and two draining into the Talley of Mexico. Mane of these 
»;i 
were recent and I noted no signs of moraines and drift rocks as these 
n < 
glaciers were a part of the system capping the mountain, ^he two basins 
draining into the Talley of Mexico are about a mile across, 1000 feet 
deep, and 3 to 4 miles long. Ho signs of glacial work goes below about 
11,000 feet and usually not below 11,500 feet. 
Having examined the country across to the border of Istaccihuatl, 
I returned to camp. The hunters were all anxious to change to a place 
on tla© point of a hill under a huge fir, and I consented so we moved 
over a few hundred yards and we had a very pleasant camp overlooking 
the valley and sheltered from the mountain winds. In looking about for 
Lepus diasi. several holes leading into the ground and evidently used 
by them were found but they usually make their forms under dense bunohes
