THE NAUTILUS. 85 



Here were the mountain trout, the Colorado river Cut Throat 

 (Salmo mykiss pleuriticus, Cope), a pound each; wild turkeys 

 in flocks of one and two hundred, blue grouse, beaver, Abert's 

 squirrel with its tufted ears, and a deep forest untouched by axe, 

 fire or wind; and please do not complain if the shell collection 

 is not as large as it ought to be. Upon this high plateau it was 

 a continuous forest of the largest yellow pine, blue spruce, 

 Douglas spruce, thickets of quaking asp 150 feet high, alder 

 and cork-bark fir (Abies arizonica, Merriam). There are wild 

 peas and black gama grass, and cattle fatter than the average 

 corn-fed herds. 



The Black river, known as the Salt river farther down, is one 

 of the beautiful streams of America. No dirty water or naked 

 banks here, but a robust forest and a sodded turf. It takes a 

 good part of an hour to climb to the plateau above. Well 

 swept lawns with enough of the large pines for landscape beauty, 

 and wide enough for the snail-hunter's camp and his horse 

 feed, either on one or both sides of the stream, and Oreohelix 

 from white to black, from high to low, in every rock pile. 



Physas and Pisidiums were plentiful in Reservation creek and 

 a few Oreohelix were in the rocks. The next twelve or fifteen 

 miles north the country was higher, with prairie parks and a 

 few lakes. Besides the few Oreohelix cooperi on the south slope 

 of Mt. Thomas there was an abundance of the Vertigos, Pupillas 

 and other small species. The trees were so close together here 

 that the horses were left at the camp and we climbed the easy 

 slope on foot. The dome-like summit of Thomas, with its 

 stunted spruces, bogs and moss, had a few shells, and none 

 were found alive. 



The scenic effect was concealed by flurries of snow. At camp 

 in the morning the snow was ankle-deep and still falling. It 

 was cold. Our packing ropes were like rods of iron, and we 

 moved. In an hour we rode into pleasant weather and the 

 days after were perfect. On the return trip the Raspberry trail 

 from the rim of the Blue mountain to the Blue river was taken, 

 landing us at Cosper's ranch. 



Down the Blue and San Francisco rivers Ashmunellas (A. 

 pilsbryana\ two new Sonorellas and Oreohelix were found in
