10 BUREAU OF AMERICAN ETHNOLOGY 



Songs of 10 classes were recorded on this trip, with old and 

 modern examples of one class. The recorded songs comprise 

 those of the water-spirit bundle, hand game, and moccasin 

 game, love songs, war songs, and a lullaby, and songs of the 

 Green Corn, Friendship, Fortynine, and Squaw dances. 



At the suggestion of Senator Carl Hayden, Mr. Neil M. 

 Judd, curator of archeology in the United States National 

 Museum, made a brief reconnaissance in September, 1929, 

 for the purpose of ascertaining the most practicable method 

 of surveying, at this late date, the prehistoric canal systems 

 of the Gila and Salt River Valleys, Ariz. Most of the ancient 

 canals had been obliterated through agricultural practices; 

 others were threatened with early destruction under the 

 program of the Coolidge Dam project. Following his pre- 

 liminary investigation, he recommended an aerial survey as 

 the only feasible means whereby the former aboriginal canal 

 systems could be located and mapped for permanent record. 



Since haste was a prime factor, in view of the extensive 

 grading operations within the Pmia Indian Reservation, the 

 War Department generously came to the aid of the Smith- 

 sonian Institution by providing an observation plane and 

 personnel. Mr. Judd left Washington January 12, 1930, 

 and proceeded to Phoenix, Ariz., by way of Tucson and 

 Sacaton. Unfavorable flying conditions served to delay 

 inauguration of the survey. Ground haze in the early 

 morning and smoke in the afternoon obscured the ground 

 except for a 2-hour period at midday. Lieut. Edwin Bob- 

 zien, pilot, and Sergt. R. A. Stockwell, photographer, both 

 from Crissy Field, the Presidio, San Francisco, pursued their 

 assigned tasks as rapidly as possible. They made approxi- 

 mately 700 exposures, of which half were vertical photo- 

 graphs taken from an altitude of 10,000 feet. These have 

 since been assembled into mosaic maps. As was anticipated, 

 the aerial survey disclosed numerous prehistoric canals not 

 visible from the ground. With the mosaic maps in hand 

 these ancient canals must now be examined individually and 

 their locations identified with reference to near-by section 

 lines. This task properly should be done during the late 

 autumn or winter months and within the next few years.
