20 MONSOON WINDS. 



well as tropical rain during the S.W. monsoon; and 

 though the quantity which falls during the N.E. 

 monsoon is greatly disproportionate to that which 

 descends in the S.W. monsoon, it nevertheless, on 

 an average of seasons, equals the quantity which 

 falls in the neighbourhood of London for the same 

 period, from November to April inclusive. The 

 quantity which falls at Canton is 11*11 inches ; at 

 Macao 13*58 ; and in London 10-28 ; whereas at 

 Calcutta the quantity seldom reaches three inches.* 

 Still, in a country bordering on the tropics, as 

 Canton, this, from the activity of evaporation, to- 

 gether with the force and aridity of the northern 

 wind, is comparatively a state of dryness. 



The quantity of rain which falls at Canton and 

 Macao during the S.W. monsoon, when the winds 

 come charged with moisture from the sea, amounts 

 to 67*85 inches; whereas during the N.E. mon- 

 soon, when the wind blows over the land> there 

 falls, as already stated, 11*11 inches ; thus making 

 the total quantity 78*96 inches.f 



But the annual quantity which falls at Peking is 

 only 27*98 inches J, which is less than in England, 

 though that capital is situated further south by 

 sixteen degrees.
