THE NAUTILUS. 41 



Jose peak, where Sonorella mearnsi dwelt at the time of the 

 Boundary Survey. 



Bound for the Huachucas to pick up better sets of former 

 collections, we dropped down the Patagonia mesa through a 

 thick grove of young oaks with cultivated ranches in the can- 

 yons. Then out upon a Kansas prairie landscape where the 

 highway crosses the head of the Santa Cruz running south and 

 the Barbacomari running north. Here are a number of prairies, 

 without brush or thorns as beautiful to the eye as any state can 

 produce. The Canillo Hills for thirty miles or more are covered 

 with a thick growth of oak and juniper. At the high peak east 

 of our road we found Sonorella elizabethae in abundance, and in 

 the limestone hills west were small colonies of Holospira for 

 three miles under spawls close to the stratified terraces, but a 

 foot or so in height. Also in the rocky hillsides. 



Across another beautiful prairie we were again in the Huachu- 

 cas at the Manilla mine, at the northwestern end. Here we 

 were comfortably housed at the property owned by some of my 

 Joliet friends, and at the home of the typical Holospira ferrissi 

 Pils. It seemed convenient to have lamps and a cook stove. 

 Again we camped in Carr Canyon, near the home of our friend 

 Biederman the entomologist and father of walnut grafting. Side 

 trips were made to Garden, Brown, Miller and Ash Canyons. 



Around the southeast point of the range we went into new 

 territory, Montezuma and Copper Canyons, and again gathered 

 Ashmunella heterodonta at Ida Canyon. These are rich canyons 

 and so extensive they have not been thoroughly explored. One 

 of the smallest of Sonorellas turned up in Montezuma Canyon, 

 Sonorella montezuma. It was found abundant in lime, granite 

 and porphyry. Again we had splendid quarters, a stove and 

 lamp, on the State of Texas mining property. These mountain 

 ridges run into Mexico, and ranchmen obtain permits from the 

 Mexicans, when they desire to journey into Tombstone, Naco 

 and Douglas with a vehicle. 



From the Huachuca camps several raids were made on the 

 Mustang and Whetstone ranges about twenty miles away. The 

 first range, about 6,000 feet, has shells in every stone-pile, and 

 the climbing is easy and clean. It is a model for collectors to
