which was probably followed by a stronger north-easterly wind over- 

 head. This npper north-easterly wind probably extended southwards 

 over North-Western India and was, I believe, an important factor in 

 maintaining the vitality of the disturbance during its passage westward. 

 The fourth depression has been doubtful. Part of it appears to have 

 moved westward, and part northward into Bengal. 



The rainfall distribution in Northern India has been well-defined, 

 and as in 1902 there has been an evident connection with the Himalayan 

 storms. During June and the first week of July, that is up to the occur- 

 rence of the more decided Himalayan storm of July 10th, rainfall was 

 almost entirely confined to Bengal and Assam. After that disturbance 

 passed over Bengal and cyclonic storms began at the head of the Bay 

 the character of the rainfall changed in Bengal. Only light scattered 

 showers fell. On the other hand, rainfall became more general in Central 

 India, and, after the Himalayan storm which began in the western half 

 of the range about the 19th, rainfall became general in the extreme west. 



The behaviour of the last depression of the series shows that the 

 change produced by these Himalayan storms in Bengal is coming to an 

 end, and while I write cloud is increasing and ordinary monsoon weather 

 is becoming general over this Province. 



It should be noticed how the west of Bihar appears to have been 

 very little affected by either of the more important of the Himalayan 

 storms. The one of the 10th July was probably confined more, as re* 

 gards after-effects, to Bengal, and that of the 19th July to the north- 

 west. The result has been that the west of Bihar and the adjacent part 

 of the United Provinces have, during the three months ending with July, 

 received less rain than they usually receive during June alone.
