EVAPOKATION OF EVEKGREEN AND DECIDUOUS TREES.

clearly the peculiar projjerties of Evergreen and Deciduous trees. 

 Of the six Evergreen plants, the water evaporated during the 

 first four months was 44 per cent, of the water evaporated during 

 the following four months; while in tlie Deciduous plants it was 

 only 14 per cent. : this would account for the large percentage of 

 loss when Evergreens are transplanted in winter. In Table IV., 

 where the water evaporated is divided into three portions, the 

 comparative proportion of the two classes of plants is still more 

 clearly shown.
