Wind. Four daily observations of the direction of the wind were 
made during 1861, but not regularly; however I assume that the 
irregularities were so irregular as in great measure to counterbalance 
each other, and the results are as follows. 
It appears that throughout 1861, northerly and easterly winds 
were to southerly and westerly nearly as 9 to 53, but from October 
to March southerly and westerly winds prevailed ; and judging, from 
partial observations, which, however, ranged over the year, the night- 
breeze was generally from the southerly and westerly directions. 
I shall now proceed to discuss the more immediate subject of the 
present paper, viz. the vegetation of the Peshawur valley, beginning 
with a survey of the cultivated plants.
