10 THE NAUTILUS. 



ilar condition was found at Fredonia, Arizona, by Ferriss and 

 Daniels in 1910. The older residents said that twenty-five 

 years before the Kanab Wash was clothed with grass and there 

 was merely a few damp spots here and there along the valley, 

 that the cattle had cut a trail down the valley and this trail had 

 been deepened year after year by the stream. In 1910 the 

 water of Kanab Wash was 90 feet below the floor of the valley 

 and a permanent stream was of such a volume as to be known 

 as a river. A recent freshet had taken out the community dams 

 storing water for domestic use at Kanab and Fredonia, and the 

 village streets were still muddy from the disaster. Perhaps 

 these two streams and many others had a big cut the same sea- 

 son and by the same freshet. We see much evidence of this 

 cutting and also of some filling. Perhaps after a stream here 

 is cut to the bed rock it again fills with brush wood and soil 

 washed from above. 



Lymnsea stagnalis appressa Say was found in the canyon peat 

 and it may perhaps still be found alive in some of the ponds 

 and lakes of the mesas. We saw the lakes but an auto party is 

 too fast for pond snails. Lymnsea (Galba*) palustris (Mull). 

 Lynvnaa proximo, Lea, Lymncea (Pseudogalba) parva, Planorbis 

 trivolvis Say, and Suceinea retusa Lea, now a stranger to the 

 locality, were also gathered; but the material was in poor con- 

 dition, the shades of night were coming fast, all alone in an 

 Indian country and it had been a twelve-hour walk. It was 

 ten before the camp fire was beckoning at Marsh Pass. 



Wetherill came to escort us to his home at Kayenta the next 

 morning, and then led us two more days on horseback through 

 Monument Park where peaks, steeples and effigies more than a 

 thousand feet high seem to stick up through the plateau floor. 

 While waiting for the snake dance, nearly a week of delight in 

 desert literature, paintings, photographs and evening lectures 

 was our lot at this club-like home. It is something of a head- 

 quarters for the government explorers, and for all sorts of 

 writers, artists and students who desire to know something of 

 the Navajos. 



The party divided here, one half returning home, the other 

 going on to the snake dance at Walpi. The journey of two
