THE MONTHLY BT'LLETIK.

Of the 209 trees, newly attacked by this fungus, that have been 

 treated (Table 4) the pereentajie of loss in all classes amounts to :18 per 

 cent, and the total percontatje of cured to 89 p(M- cent. Tliis last figure 

 should be considera])ly increased from the "still gumming" trees; and 

 although the number of dead trees will probably increase somewhat, I 

 doubt if the increase will amount to more than 5 per cent of the total

number of trees treated. Taking everything into consideration — the 

 freeze and its effects on the gummed trees, the bad condition of some 

 of the trees when the disease was discovered, and our comparatively 

 short experiments with the treatment — the results so far obtained may 

 be considered as fairly good.
