P. PEARSON 1952 67 May 17 5 miles N. Mageo, 2500 ft. Temp. 6 a.m. 57°. Ainto amble in middof night to see a house mouse running around the head of our bed. Caught it. This is very barren stony desert (see moire) although a few dry springs of an animal could be found in a nearby gully. The vegetation of the Mageo valley was about 3 miles away and about 1/2 mile in other direction was a dry wash with ephedra-like bushes. Also seen at our campsite were small moths (discovered by turning over stones), spiders (also under stones), a large green beetle (under sleeping log, possibly a stow-away), and a small hummingbird came at 7 a.m. to investigate the red striping on the bus. Heard lats during the night. Stopped to watch at a stream about 25 km NW Mageo, 1700 ft. (leaves, thorns, compound leaves). Mimersona millvina, acacia-like tiny bushes, a small delicate cane fern, a fox and very large frog scrambled on bridge. Stopped for night in sandy desert about 10 mi N Carite. Sandy hills with scattered rocks. Only vegetation is lichens on the larger rocks and Brownelocks some in bloom. They are quite rotten, probably depend on fog. Mimersona mouse burrows, fox?, and lizard tracks. Many moths came to lantern after dark. Several corn moth skeletons lying about. Put out about 20 ms. May 18. Stanny sea-stone feel in the morning. One Phyllotia in my traps. Took moire of the rotten brownelocks
