Station No. 47. — GM Fort Lowell, Arizona. This abandoned 

 military post, also known as Camp Lowell, is located on Rillito 

 Creek, at the foothills of the Santa Catalina Mountains, 6 miles 

 northeast of Tucson. The stream is clear and contains fishes. Its 

 banks are beautifully wooded with cottonwood, willow, boxelder, 

 elder, ash, and grape. A mesquite-and-cactus country borders it on 

 the south and the foothills of the Santa Catalina Mountains on the 

 north. The cacti are very characteristic of the country adjacent to 

 the Santa Catalina Mountains. Besides the giant Cereus and the genera 

 Cactus, EcJiinocactus, etc., there is a remarkable profusion of and 

 variety in the genus Opuntia, of which 0. acathocarpa, O. arhor- 

 escens, 0. arhuscula, 0. leptocaiilis, and 0. fulgida are among the
