128 Second Memoir with reference to [No. 98. 



The Canal station of Dadoopoor is situated below the junc- 

 tion of the Somlie and Putteallee rivers with the Jumna, on 

 the right bank of the latter ; lat. 30° 12' N. and long, about 

 77° 23' 45" E., about 16 miles from the southern base of the 

 Sub-Himalayas. 



Extract from Mr Dawe^s Report — 



" The evening of the 20th was clear, with a light easterly wind, 

 " the fore part of the night ; moon light, without a cloud. About 

 " llh. 30m. p.m. distant lightning was perceptible in the NW. 

 " quarter, and about midnight, thunder was heard in the same 

 "direction. At lh. 30m. a.m. of the 21st, the storm came on in 

 " sudden gusts, accompanied by a continual roll of thunder 

 u and vivid streams of lightning and rain, driven along with great 

 " force, nearly parallel to the earth. The latter only continued 

 " for about half an hour,* but the storm did not totally subside 

 "till about 3 a.m., when it fell a dead calm, and towards 

 " daylight the sky was quite clear, with light airs from the 

 " eastward. The direction the storm took was from the NW. 

 " to the SE. This storm appears to have been more extensively 

 " felt, than those which generally occur in this neighbourhood. 

 " By reports which I have received, it appears the same ravages 

 "have been extended as far down as Kurnaul, and upwards 

 " from this to the foot of the lower Hills, (as I have personally 

 " observed) . There appears to have been no abatement in the 

 " force of the storm, for I witnessed in my route yesterday 

 " (to the Canal head) trees of immense size torn up by the 

 " roots." 



I append an extract from the Meteorological Register kept 

 here, from the 18th to the 24th instant, inclusive. 



I have directed the attention of the Overseers employed un- 

 der my orders at Kurnaul, Hansi, and Delhi, and two inter- 

 mediate stations, to the registry of storms, and on the occurrence 

 of such phenomena I will do myself the honor to forward a 

 combined report of their observations. 

 I have the honor to be, &c. 



W. E. BAKER, Lieut. Engineers. 

 Superintendent Delhi Canal. 



* The quantity of rain which fell during this storm was 0.91 inch.
