On January 21 the temperature again fell to —12°F. and 
remained approximately at zero through the following day. Bud 
collections were made on January 23. The losses in moisture at 
this time are set forth in table III.

In this instance it will be observed that the foliage buds in Stella 
and Tonka lose 2.06 per cent and 4.7 per cent respectively, while 
there is still practically no change in those of Assiniboine. Likewise 
the fruit buds in Stella and Tonka show a loss of 1.64 per cent 
and 5.25 per cent, while Assiniboine fruit buds show the almost 
inappreciable loss of 0.05 per cent. Again, on March 4, the 
_ temperature fell to o° F. and on March 5 to —9° F. Bud collections 
made on March 5 showed losses in moisture content, as given in 
table IV.

On this date the moisture content of foliage buds in Stella 
decreased 1.38 per cent and in Tonka 3.6 per cent. The foliage 
buds of Assiniboine here show a loss of 4.33 per cent, which is not 
in accord with the data shown in tables II and III. This high 
percentage, however, is undoubtedly due to some error in the 
determination of moisture content for February 21, the value
