a little distance from the ocean, the mean annual rain-fall sel- 
om much exceeds 10 inches; and there are apparently regions 
of great extent in Asia and North America where the annual 
rain-fall is less than 10 inches. 
Were more precipitous; also that the proximity to the ocean 
probably balances in some degree the deficiency of rain-fall 
which would otherwise exist on the eastern side. Neverthe- 
less it seems incredible that this range should not exert a pal- 
pable influence on the amount of the rain-fall, particularly 
rt of 2000 feet elevation; one of 1720 feet, one of 1530 
continued for a few years, it is not doubted that they would 
show that the Alleghany Mountains exert an appreciable influ- 
ence on the amount of the annual rain-fall. It is not, however, 
believed that this influence is as decided as that of the moun- 
tains on the northwest coast of America, or those on the 
Coast of Norway. The Alleghany Mountains correspond more 
nearly to the Ural Mountains in Russia, whose influence upon 
the rain-fall is small, but nevertheless appreciable.
