S. A. Hill— Tornadoes and HallHorms of April [No. 2, 



does not seem to have been anywliere quite a mile, and if this be ac- 

 cepted as the diameter of the dangerous area, the duration of the 

 destructive wind, with the above-mentioned rate of progi'ession cou.ld 

 not much exceed two minutes. 



(2.) The Mawana storm was a small one occurring late in the 

 evening. It passed eastwards, crossing the Granges into the south of 

 the Bijnor district, and the north of Moradabad (Thakurdwara). It 

 may have originated in the afternoon and crossed over into the Doab 

 from the districts west of the Jumna, but I have no information on 

 this point. 



(3.) The Badaun storm, also of no great importance, probably 

 travelled nearly from west to east along a path stretching from Gunnaur 

 to the north of the Budaun tahsil, parallel to, and simultaneously with, 

 the Moradabad storm. Regarding the time of occurrence there is, 

 however, a conflict of opinion ; it is stated to have occurred later as 

 Gunnaur than at Bndaon. If this be so, it must have travelled from east 

 to west in a contrary direction not only to the other storms of the same 

 and following days but contrary also to the usual coiirse of all tornadoes 

 which have been observed, at least in extrati'opioal countries. 



The probable courses of (2) and (3) are shown on the charts, but 

 there is no means of determining the whole distance traversed or the 

 velocity of progression.

The above table shows that there were at least two violent storms 

 over the region on the afternoon of the 1st May, one of which passed 

 over Delhi and Ghaziabad and the other over Tilhar and Shajahanpnr. 



(1.) The Delhi storm apparently approached that city from the 

 west or north-west, passed over Delhi about half-past 3 in the 

 afternoon, crossed the Jumna to Ghaziabad, where it was still of extreme 

 violence and accompanied by enormous hailstones, and in the course 

 of evening, time not stated, reached the Sambhal and Hasanpur tahsils
