b THE NAUTILUS. 



around the base of the mountain on horseback to the Rainbow 

 Bridge. On the mountain top an Oreohelix depressa came to 

 the surface following a shower of rain, in every way almost 

 identical to the shells found by Henderson and Daniels at 

 stations 22 and 23, 1915, near Ogden, Utah. The forest rub- 

 bish about the springs was alive with Pupas and Zonitids and 

 Vallonias. A few Oreohelix yavnpai neomexicana Pils. were in 

 the rock slides. 



The outlook from the crest overlooked the Rainbow Bridge, 

 the canyons of the San Juan, other canyons ; bridges, caverns, 

 domes, sunlights and shadows, white, brown, and all the reds 

 and all the shades of the amethyst. Also the plateaus beyond 

 the Grand Canyon, the Henry Mountains, 11, 410 feet, the Blue, 

 11,445, Aquarius 10,100, LaSal 12,271. Also the white and 

 black mesas and the Carrizo mountains to the south and east 

 were in view. 



The Rainbow Bridge is in the strict rainbow form and with 

 some of its colors. But 30 feet in thickness, with its 309 of 

 altitude and 208 width, in lightness of architecture it seemed 

 something of steel. The average camera does not give an 

 accurate estimate of sharp hillsides and scenery large as this 

 bridge. 



It rained a little these evenings, but the bridge kept us dry, 

 and at a camp in Surprise Canyon blankets were spread in 

 wind holes of the cliff. To imitate the swallows, heads and 

 feet were made to peep out a little. At the bridge one of the 

 party imitated the pack rats for a little while and for the first 

 time in his desert experience made a complete collection of fleas. 

 The chute of Zane Grey is an interesting feature of this trail, so 

 narrow it seemed the walls in passing could be touched with 

 either hand, and so high the passage was gloomy. Abduction 

 Cliff and the balanced rock that exterminated the wicked band 

 were true to photographs, one on the trail the other at Navajo 

 Creek, thirty miles away. 



In fiction, details in scenery and character should be true to 

 life, though a little latitude may get through of a geograph- 

 ical character. We know Grey's Roaring River, and we 

 camped for weeks at the corral he helped to build for Silver
