Third District—In Arizona and New Mexico there is a general maxi- 
mum of rainfall in summer, and a restricted maximum in winter. The 
principal minimum is in spring. In Table XI the stations are arranged 
according to longitudes, a disposition well suited to exhibit their relations. 
In eastern New Mexico the distribution of rainfall has the same character 
as in adjacent Texas, but with a more decided maximum. Half of the 
total rainfall is in summer and half of the remainder in autumn. Westward 
the maximum diminishes slightly, but it appears in every station of the two 
territories. In western Arizona the winter maximum .of the Pacific coast 
asserts itself, and it can be traced eastward as far as Fort Wingate, New 
Mexico Except at Camp Mohave, on the western border of Arizona, it is 
inferior in amount to the summer maximum.
