Much more rain falls annually in the United States than in 

 Great Britain, if a few mountain districts in the latter be except- 

 ed ; but the mode of falling is different in the two countries. 



The following table will serve as an illustration of this subject, 

 although being drawn from single years, it is not strictly accu 

 rate as regards each locality : 



* Average of 15 years 



In England, more rain falls on the West than on the East 

 side of the Island ; and the practical effect is that more green 

 crops, which require more moisture than grain, are grown on 

 the former; such crops making a larger return on the western

 of rather more than 112 tons on each impei-ial acre ; so that the 

 mean annual weight of rain falling in the United States, exceeds 

 the mean amount of rain on the eastern coast of England, by 

 several hundreds of tons per acre. 



138. Another important consideration is (a,) the season of 

 the year in which rain chiefly falls; and (b,) the distance of
