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 ariver. 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. 
Lymnea 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. Lymnza (Galba) palustris (Mull). 
Lymnea proxima Lea, Lymnea (Pseudogalba) parva, Planorbis 
wivolvis Say, and Succinea 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
