An eight-inch, smoothe-bored, full-choked barrel of lighter weight was screwed into place. The very neat bit of work was done by Mr. W. H. Wil- shire of Cline & Cline Co., Los Angeles, California.

Dust shot penetrated twenty-five sheets of napkin tissue paper. With no. 9 shot the penetration was sixty-one sheets of paper. With this arm the writer has collected Spotted Owl, Long-cared Owl, Cooper Hawk, Mountain Quail, Hybrid Flicker, many smaller woodpeckers, and some hundreds of smaller birds. In addition to birds, ground squirrels, elnpmr. nks, lizards and snakes have been taken. The herpetologist needs no other arm. Of course if you are going on a regular collecting expedition, take a
