young caterpillers which require vigilance to keep them from spreading. At that 

 season there are no caterpillars on our Black Walnuts. Later on a very few 

 may appear, but in such small numbers that it appears as if, so far, the Black 

 Walnuts have found no special enemy in their new home. The strong aroma 

 emitted by their leaves may tend to keep away caterpillars. 



GOOSEBERRY FRUIT WORM. 



Sir, — Last year our currants and gooseberries were webbed together by some insect 

 with a web resembling a spider's web. When the fruit was ripe, a green worm resembling a 

 cabbage worm was found. Fully one-half the fruit was de.stroyed.

This pest is no doubt the gooseberry fruit worm. According to Mr. Saun- 

 ders' " Insects Injurious to Fruits", it spins its silken cocoon in the leaves or 

 rubbish and remains in a small brown chrysalis until the following spring. In 

 the month of April the moth appears and deposits its eggs in the young goose- 

 berries soon after they are set. As there is only one brood during the year, they 

 may be more effectually destroyed by hand picking, particularly as its habits are 

 such that its presence can be easily detected. All berries coloring prematurely 

 should be examined and the larva destroyed before it escapes to the ground. 

 The leaves or rubbish under the bushes should be gathered and burned and the 

 ashes scattered freely over the ground in their places. Dusting the bushes freely 

 with air-slaked lime early in the spring helps to deter the worms from deposit- 

 ing their eggs on the young fruit as it forms. 



PLUMS FOR LACHINE, QUEBEC. 



Sir, — Would you please advise me what kind of plums would do for this district ; an 

 early, medium, and a late variety ? The kinds I see mentioned for South Ontario are too 

 tender here. The Damson bears well but is not profitable. Are those western kinds — 

 Weaver, Mariana, DeSoto, etc.— of any decided merit? I have planted some Moore's 

 Arctic, but have seen it unfavorably spoken of lately.

 Reply by A. A. Wright, Renfrew, Ont. 



In reply to Mr. C. P. Newman's letter, asking for information about Weaver 

 and DeSoto plums, I can state that they are undoubtedly good varieties for 

 northern latitudes, not only as regards hardiness and productiveness, but also as 

 regards quality. Mariana, I know nothing of. Moore's Arctic is too tender for 

 us here, but doubtless will succeed with him. But Mr. Newman is in a very 

 favored locality — considering his northern latitude — for, owing to his insular 

 position, and consequent exemption from early fall frosts, he can grow varieties 

 that would be perhaps more saleable than any of these above mentioned. For 

 example. Corse's Great Bearer or Bradshaw, both dark color, for early, or, if he 

 prefer a yellow, take Yellow Gage ; Admirable, for medium, and Victoria, for late.
