 western portions of the Plateau region and in California. 

 Along the middle and South Atlantic and Gulf coasts nearly- 

 normal conditions prevailed. In the upper Lake region, 

 lower Ohio valley, throughout the Mississippi and Missouri 

 valleys and the eastern Rocky Mountain slope the week was 

 warmer than usual. Excepting the northern portion of the 

 upper Mississippi valley, and limited areas on the southern 

 New England and Florida coasts, and in Tennessee, the 

 week was drier than usual. In all other districts east of the 

 Rocky Mountains there was a total absence or an inappre-

 nearly normal temperature conditions prevailed along the

 interior. The temperature fell to the freezing point in 

 extreme north-western Dakota, north-eastern Montana, and 

 also northern Nevada, but on the whole the minimum tem-

 From the southern New England, middle and South Atlantic 

 coasts westward over the central valleys, including the 

 northern portion of the Gulf States and the lower Lake 

 regions, the week was practically without rainfall, except 

 over a few limited areas. Good rains fell over the northern 

 portion of the upper Lake region and over portions of

 The week was excessively hot and for the most part dry in 

 nearly all districts east of the Rocky Mountains.
