of the mountain lie the ruins of many dwellings and on top, 

 carved from the solid rock, is the Aztec god standing guard over 

 the silent city. Near by on a large flat rock are the basins, or 

 cups, carved in the rock, that held the bleeding hearts of the 

 unfortunate victims that were sacrificed to appease the wrath of 

 this stone god. History tells us that often the victims were 

 pretty little girls chosen from among the thousands who visited 

 these Aztec cities every year during the great fiesta." 



Aztec legends tell us 2050 burro loads of white silver and 905 

 of gold and silver were buried by those Indians a certain num- 

 ber of paces from a certain point, but the rare and noble Sonorella 

 walkeri aguacalientensis P. & F. was again discovered by us in a 

 small group of hills on Josephine Canyon between the Santa 

 Ritas and the Cayetanos. Three new Sonorellas were dug up 

 in the Tumacacoris, S. tumacacori, S. hinkleyi fraterna and S. 

 walkeri montana ; in the Cayetanos S. hinkleyi and S. cayetanensis. 

 Miss Pilsbry put the Mission on canvas and sketching pad. 

 Camp gathered many kinds of bats and lizards. Others have 

 given a lifetime here at Tubac, digging and exploring, tormen- 

 ted by cat-claw, cacti and rough traveling, but have not found 

 the Aztec gold or silver. 



These many generations of miners have left but little timber 

 on the hills. A few oaks on the mesas and peaks, and only in 

 the heads of deep gulches is there anything like reforestation. 

 In earlier days, with Arizona snail hunters it was at least a 

 climb of 8,000 ft. for Sonorellas, and rock covering of three feet 

 or no work. In the Cayetanos without regard to elevation they 

 were found in the soil next to boulders and under spawls lying 

 about the gravelly cliffs. Often a cliff or rock slide ten feet 

 square would yield a cocoa-can full. Once we obtained two 

 cans full, 452 by count, and all albinos except 24. Near the 

 peak of the highest mountain at the southern end of the range, 

 on the north-east side, is a gentle sloping cove of about forty 

 acres of Sonorella rocks. But the sun was just going down as 

 it was discovered and only a few Sonorellas were gathered. 



The Pajarita Range is a wide expanse of rolling hills, a 

 continuation of the Tumacacori, on both sides of the interna- 

 tional line, timbered, well watered and sodded. The Governor
