noticed that the rate of evaporation was nearly constant, aver- 

 aging about ^ centigram per hour. — 



It has been said that the rate of the loss of moisture from trees 

 in winter determines the relative hardiness of different varieties 

 of apples, and of some other fruits. The following table shows 

 studies of twigs of varieties of diiferent degrees of hardiness, but 

 it will be seen that the per cent, of loss of moisture bears no 

 relation to the supposed hardiness of the varieties:

♦Supposed to be the hardiest varieties. 



Early in April, twigs, from the previous year's growth were 

 taken from several varieties of apples, which vary much in their 

 ability to endure our climate. The twigs were carefully weighed, 

 and the cut ends were, then sealed with wax to prevent evapora- 

 tion save through the bark. At the expiration of two days the 

 wax was removed and the twigs again weighed. The twigs were 

 kept in an open shed.
