April to pick off all the leaves which are blis- 
tered and appear brown on the upper surface. 
At this time there will seldom be found more than 
one insect in each concave, but by those being taken 
off and burned, a vast increase will be prevented. It 
will be proper to look over them a second time at 
the fore end of May. If it is necessary, the 
Mixture (No. 2) may be applied any time after 
the fruit is well set to the time of ripening. Pre- 
vious to the application, the twig ends, with the 
inincipal blistered leaves, should be picked off; 
a boy will go over from one to two hundred bushes 
in one day, after he is acquainted with the effects 
they produce. The Mixture should be then care- 
fully applied with the engine over the Bush, and 
two boys, prepared with the wisk, must smartly 
and carefully wisk the bush upwards, and never 
strike downwards, as it would split the leaves, and 
break the young shoots. The wisk will break or 
disperse the Mixture into small particles, and at the 
same time it will be forced under the leaves, which 
otherwise would use several times the quantity 
without getting among the insects so effectually, 
and, of course, the waste would be much greater. 
If the above practice be properly managed 
twelve gallons will do from thirty to forty large 
trees. 
Root Aphis.— The roots of the Currant Bush 
particularly the small fibrous roots, are sometimes 
infested by a small species of the Aphides, it is 
smaller in size than any of the preceding ones
