Several circumstances combine with the much diminished rainfall 
. of summer te increase the heat at that season; viz., the valley being 
walled in on all sides by hills, these being very bare of vegetation, 
so that they absorb heat freely during the day, which is as freely 
radiated in the night, and the generally clear summer nights which 
also favour radiation. 
I am sorry that under the head of daily range of temperature, I can 
only give the following figures for three months of 1861. These how- 
ever I can certify as reliable, the observations having been made by Dr. 
J. J.T. Lawrence, who has devoted much attention to the study 
of meteorology in various par 
ts of the Punjab.
