side of rocks we found Arctias too cold to move. A few 

 minutes later we were upon the moor and the wind was 

 searching every opening in our clothing and chilling us to 

 the marrow. There were no rocks whose shelter we might 

 seek here, but as we still had hopes of sunshine we bent our 

 heads and pushed on, now and then starting a Chionobas 

 which, carried by the wind, never stopped until it fell below 

 the mountain crest and could rest in some sheltered nook. 

 We sought out hollows in the earth, and dropping into them 

 lay upon our backs trying to get warm. Near one of these 

 shelters we found two old ptarmigans with their young and 

 caught two of the little birds — beautiful creatures, like young 

 chickens — and watched them until we could no longer endure 

 the mother's anxiety and plaintive calls for her brood, then 

 laughed to see them scurry away and imagine themselves 

 hidden when they squatted in full sight among the scant 

 vegetation. 



The clouds became thicker, and when we could no longer 

 endure the cold we decided to go back to the steep side of the 

 range and descend into the gulch above camp hoping, if the 

 sun came out, to find Erebia magdalena in the slide rock. It 

 took but a few minutes to gain the protection of the rocks at 

 the edge and to start upon our way down over the half mile 

 or more of slide rock, where we did not dare to walk in a line 

 for fear the ones above might dislocate rocks, which would go 

 hurtling down upon those below. 



The sun finally broke through the clouds and a few butter- 

 flies started to life at once. Within the rim of the basin is an 

 old mine with a bin built for the storing of ore, and upon the 

 floor of this bin we lay and enjoyed the reflected heat of the 

 sun until some of the chill had departed, then worked on 

 around the rim until in another great area of slide rock we 

 suddenly started a magdaleria. How one longs for these black 

 beauties as he sees them flying royally away, moving so easily 

 over the great fields of loose rock where one misstep may 

 mean a broken limb. We were fortunate this morning, and 

 three magdalena were taken. 'Then we found Chrysophanus 

 snowii among some of the larger rocks and all heartily entered
