ure, with its jerky flight, but we manged to capture a nice series. 
A little higher up, in a draw or small canyon, we found Thecla 
crysalus, a butterfly of an unusual shade of blue. Grasshoppers 
of a number of species were in evidence, but other insects were 
scarce in comparison with the nuch richer Wasatch mountains. 
From morning until sundown we explored within a radius of some 
miles, as far as we could cover on foot in a day, but the high moun- 
tains were still beyond and lured us on. After going up rises of 
hundreds of feet we found other hills still beyond and deep canyons 
that were not seen until their edges were reached. In the distance 
impenetrable oak and aspen thickets looked like well-cropped 
lawns. Peaks that looked as though one might walk to them in 
a few hours were days away and had to be reached by circuitous 
routes by means of saddle and pack horses. In a beautiful little 
valley at 7000 feet, almost hidden by aspen and fed by a splendid 
spring, we found the true Argynnis chitone, one of the silver-spotted 
butterflies. About a thousand feet higher a species of moth ( Pseu - 
dohazis) was flying; it has a flight much like a Papilio. On the 
23rd of July, after due preparation, we started on our trip to the 
higher altitudes. Mr. and Mrs. Sullivan also concluded to take 
a vacation, as they were fond of camping and outings in the moun- 
tains. 
Four good saddle-horses and a pack-animal were a part of our 
necessary equipment. The weather was ideal and the mountain 
scenery very beautiful. 
The La Sal is a National Forest Reservation and our objective 
point was the Warner Ranger Station at an elevation of 9,490 
feet. From this point we could see the top of one of the big peaks 
rising some thousands of feet above us. Here were some interesting 
stands of forest trees and in the glades we again found the silvered 
butterflies and other species not taken at lower levels. A night 
and part of a day were spent here and then we went still higher 
to the saw-mill, where we wished to collect, at 10,000 feet altitude. 
From this place we had an excellent view of Mt. Peale which rises 
to 13,089 feet. Engelmann spruce grow to a huge size at this 
elevation and we saw some specimens that may have been three 
hundred years old. The tops of the mountains are bare and covered 
with talus, but plants such as Polemonium confertum, Erigeron 
trifidus, Arenaria obtusifolia, and Claytonia megarrhiza grow at
