Hoffmeister 1942 Itinerary 5 mi. E & 1 mi. S Mono Milla, 8300 ft., Mono Co., Calif. yellow pine predominating. The pines are rather widely spaced, the area are not large in diameter or height, and has not been logged. To the west is a small, unnamed creek which flows towards Mono Lake (in that general direction). This part of the Glass Mountain Range is unique in that yellow pines come down to the Artemisia association, and there is no or little pison between. Along the road to Johnny Meadow there are no pisions between the yellow pines and Artemisia and this is almost universally true west of Dexter and Wet creek canyons. In the cooler canyon bottoms and on the protected higher slopes, there are in the vicinity of our camp, large aspen thickets. Also in these situations there is Pinus flexilis. As we made camp, we saw a small group (4+) of Odacoileas hemiconus. June 19 Set out 25 mouse traps late last evening in the Artemisia beneath the yellow pines. Caught 6 Peromyscus maniculatus. Pitelka caught 1 young Peromyscus truei in traps set in similar situations beneath young yellow pines and Artemisia. It is noteworthy that this young P. truei was taken in this nearly pure stand of yellow pines, with no pisions for miles as far as I can ascertain. Shot 2 different species of Eutamias. The larger one (no. 853) was on a limb of a yellow pine 12 feet above the ground. It ran here it taking refuge upon my approach. The other (no. 854) was shot
