THE NAUTILUS. 39 
of the state of Sonora has built a barbed-wire fence along the 
line to keep the cattle thieves on theirown 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 walkeri 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.
