FALL NUMBER Be 
rains probably dilute the oil to such a degree and wash it off 
so quickly that no discoloration can result in streaks. Again, a 
comparatively late attack of the mite will result only in smooth 
russets and practically no buck-skin effects. In any case, how- 
ever, it is evident to everyone who observes the presence and 
activities of the enormous numbers of mites on heavily infested 
trees that the devitalizing effects of this pest on trees must be 
more in proportion to their numbers than to their size. 
The immediate and most striking loss to growers due to the 
unhindered development of rust mites in bearing groves is of 
two kinds: the discoloration of the rind of fruit, and stunting 
effect on the fruit growth occasioned by the injuries on the 
rind. The devitalizing effects on trees necessarily also affects 
fruit size but probably tells heavier on the performance of trees 
the following season.

he has sprayed every month with ’’miserable oil.” Some of it 
is, we'll say!
