36 PLANT LIFE ON THE FARM. 
water given off from small flower pots containing plants, 
grown without manure, was as follows :—

or, say, an average loss for each pot for the whole period 
of over one hundred thousand grains. ‘To show the effect 
of the season, it may be said that the average daily loss in 
grains in ‘the case of flower pots containing plants of 
wheat grown in unmanured soil, was :

Barley lost more in April and May than the wheat, 
and more also in July and August. Beans lost much 
less than either of the cereals, the amount increasing 
regularly to June to July, and diminishing in August. 
Peas evaporated less than beans, especially in June. The 
results obtained from the plants grown with various ma- 
nures were less giniform, and need not here be cited, the 
object being merely to illustrate the large quantity of 
water evaporated and its gradual increase with the de- 
velopment and growth of the plant and the advance of 
the season. While the precise effect of any particular 
manure in promoting either absorption or transpiration 
is not fully known, it has been shown that the alternate 
use of pure water and of manure water has resulted in a 
large proportionate amount of water being absorbed and 
transpired by the plant, and a greater development of 
the plant than is the case where either fluid is applied 
alone (Vesque).
