Oct. 23,1916 Daily Transpiration during Normal Growth Period 
177 
Corresponding determinations for a later 10-day period in 19x5, July 
27 to August 5, are given in Table VIII, which includes all crops in the 
1915 daily transpiration measurements. The earlier maturing crops con¬ 
sidered in the preceding table (VII) show a transpiration during this 
period amounting to 16 per cent of the total, compared with 26 per cent 
during the July period. Many of the crops were harvested soon after 
the termination of the July-August period, but the data given in Table 
VIII show that they were still transpiring actively.

The alfalfa and amaranthus measurements given in Table VIII repre¬ 
sent the first crops, which were harvested at the close of the period. 
These plants, together with Sudan grass, show a markedly higher trans¬ 
piration loss than the small grains.
