" 17 4-53 " 82-91 69-72 Cloudy 



In 192 1 in every instance rain came in nearby stations and at camp (one 

 exception) when congresses came. The stations average .14-1.10 inches per 

 station, the maxima range from 79°-95°, the minima 66°- 72°. In 1922 rain 

 came in every instance in nearby stations from i to i .06 inches per station or 

 always at camp (4 exceptions). The air maxima were 8i°-96°, air minima 



66°-74°. 



With these subterranean animals, like the spade-foots, warm rains at least 

 0.5-1.0 inches or very humid conditions seem needful to start it calMng 

 vigorously. It may start at minima of 6o°-67° but the minima of congresses 

 are usually 66°-74°. Humidity is, however, the important factor.
