N.O. Rossol 3 mi. NNE Canyon, 8400 ft., Yellowstone Park, Wyo. Sept 5, 1967 The purple finch taken is the first one seen on the trip. She looked like an old weather beater & Old Broad patch still not feathered. The Zapus been taken are as fat as they can be. I'm scraping the skins, then soaking in white gas over night. After drying the hair in sawdust they are packed flesh side out in wet paper towels to remoisten the skin. Otherwise the skin becomes so dry in the process of drying the hair, that it cannot be stitched close. In evening made 3 small steel sets, baited with bird bodies, in the area where flying squirrel was taken. Then added a few more mouse traps to line. Sept 6 1967 Tooke 4 Zapus, , Clethrionomyx, imm Mic. richardeoni + 1 Perom. maniculatus. These "Clethriss" must be busy as this & had large milk glands & had 4 large embryos!
