 Brandenburg {Mo. Weather Rev., 38 {1910). No. 5, p. 770). — This is a brief 

 statement regarding experiments undertaken near Wagon Wheel Gap, in ]Min-

 States Geological Survey and the Forest Service, " to determine as accurately 

 as possible the difference in behavior of two streams, one flowing from a water- 

 shed which is covered with forest growth, and the other fi'om a watershed 

 which has been denuded of its forest cover." The streams on which the 

 measurements are to be made are small tributaries of the Rio Grande.

 The discussion is summarized as follows :

 continuous since that time, and at the present time about one-half of the land 

 is denuded. 



" Deforestation has had no appreciable effect on the precii)ltatlon.

 and the improvement of the small streams may have increased the rate of 

 run-off slightly."
