17U METEOROLOGICAL OBSERVATIONS AT CARXWATH. 



temperature of the ah 1 , and of the ground at two stations in the 

 same wood within 100 yards of each other, and under the same 

 conditions as regards height above the ground and the sea, and 

 slope of surface, etc., but differing in the important particular, 

 that while the one is completely shaded by the trees from direct 

 solar and terrestrial radiation, the other station is open to these 

 influences, the instruments there being placed on a grassy patch, 

 about 50 feet in diameter, surrounded on all sides with trees of 

 various sorts, varying from 40 to 50 feet in height. We need 

 scarcely add that, in thus pursuing this line of investigation, other 

 important questions in connection with the influence of forests on 

 climate will be brought under examination and discussion.
