THE NAUTILUS. 39 



of the state of Sonora has built a barbed-wire fence along the 

 line to keep the cattle thieves on their own side. Although not 

 in the cattle business we did not cross over. It was a different 

 country in character from anything seen in Arizona, and so 

 pleasing we camped in these hills for three weeks. 



We spread our blankets under the wide branches of the live 

 oaks and visited the Phil Clark ranch. A couple of caged eagles 

 were at the door and young Clark was found reading by lamp 

 light with a fool quail perched on his shoulder. This is one of 

 the rarest of the quail family, a good introduction. We talked 

 birds and things till a late hour. Clark junior led us to the 

 snail slides and the bat caves the following day, and ever after 

 was a very helpful companion in our excursions. The first day 

 out he heard something in an old mining tunnel he was explor- 

 ing for bats, and a shot in the dark brought a wild pig. We 

 ate about all but its head and feet. We camped again in Pina 

 Blanca Canyon at the Moon U. S. Forest Station, and I went 

 with Clark to the Bear Canyon, a scenic picnic resort, and 

 found Asplenium firmum, a fern rare even in Florida, and again 

 rediscovered Agave parvifolia, the smallest of the century 

 plants. We picked up a new pin-cushion cactus large as a table 

 bowl. Also a pair of whip snakes for Camp. We found Sono- 

 rella ivalkeri montana here and at the Tumacacori pass and it was 

 also found by Hinkley at the Montana Mine, near Oro Blanco. 



Among the smaller Sonorellas in the Pina Blanca Canyon and 

 again across the mesa in the Tumacacori, the first Bulimulus for 

 Arizona was noted living in a strange situation, for it is a snail 

 of the grass and brush. 



At old Calabasas at the mouth of Sanoita creek, emptying 

 into the Santa Cruz, junction also of the two branches of the 

 Southern Pacific Railway entering Mexico, we camped a few 

 days to work that end and the best of the Cayetanos. Again 

 we were in claw and thorn desert surroundings. At the Mission 

 robins by the thousand, bluebirds, thrashers, cardinals and jays 

 and Gamble's quail came after the hackberries, but the Calaba- 

 sas camp was a little tame. However Camp secured rats, mice 

 and gophers on the kangaroo plan, and our luck in snails was 

 pleasing.
