Possibly such a course would be the wiser one in the end, but 
‘a bird in the hand is worth two in the bush,” and I fear the fruit 
growers have no patience to sacrifice a present advantage for an 
ulterior good. 
There are two broods of this moth; the first is on the wing 
about the time of the opening of the apple blossoms, when each 
female deposits her tiny eggs singly in the calyx-end of the apple ; 
and, as each moth deposits on an average about fifty eggs, it is easy 
to see how rapidly the insect may increase. There is a second 
brood of the moth in the latter part of July, but, if the first brood is 
destroyed, the second will be, of course, destroyed with it. Hence 
arsenites, applied once of twice in June, will ensure a fairly sound 
crop of fruit. 
Year by year less poison in dilution is found to be sufficient to 
accomplish the purpose. One pound of Paris green to 200 gallons 
of water is the usual prescription, but many experimenters have 
found that 250 gallons will not form too dilute a mixture. 
Formerly it has been necessary to depend upon American 
inventors for tools for this work, but there are one or two spraying 
pumps invented in Canada which now answer our purpose well. 
How best to cope with the Curculio has long been a problem. 
Not only are the plum, apricot and peach stung and caused to drop 
by means of its evil doings, but the apple and pear are also subject 
to its ravages, and, asa result, are much knotted and ill-formed. On 
this account the apricot is little grown in Southern Ontario where it 
might, otherwise, succeed well, and many fruit growers are even de- 
barred from engaging in the cultivation of plums. 
Until spraying with Paris green was introduced, jarring of the 
trees was the only method adopted and, where faithfully performed, 
has been, on the whole, successful ; some experimenters claim that 
it is more effective than the use of Paris green. The operator jars 
the tree with a sharp tap of a mallet and the ‘“‘little turks” are 
gathered up in a sheetand burned. This must be continued every 
day until the plums are well grown. It is a much simpler plan to 
give the orchard one or two good sprayings, which will suffice, unless 
constant rains wash off the poisons, providing always that the first 
application is made almost as soon as the foliage appears, in order 
to destroy the parent beetles. The preferable method is scarcely yet 
settled. Professor Green, of the Ohio Experiment Station, strongly
