The Bud Worm. 



1163. Sir — Would you please give me the 

 name of enclosed grub found on the apple leaf, 

 and what is best to destroy it ? 



Oakville. C. W. Martin. 



The larva sent to us by our correspondent 

 is the well known Bud Worm ( Tmetocera 

 ocellana). Early in spring-, when the buds 

 beg^in to open, it eats out the centres of the 

 buds and later webs together the leaves for 

 self protection. The best remedy is to 

 spray the infested trees with Paris green. 



Apple Aphis. 



1164. Sir, — What is best to do for a tree 

 having lice on the bark of the limbs ? 



Oakville. C. W. Martin. 



The apple aphis, cherry aphis, rose aphis, 

 etc., can be easily destroyed by spraying 

 with whale oil soap, Gillett's lye, or kero- 

 sene emulsion early in the season, before 

 the leaves begin to curl. It is best to make 

 one strong application just before the buds 

 open out. 



Hybridizing of Cucurbits. 



1 1 65. Sir, — Will you please to answer the 

 following questions in an early issue of your 

 valuable monthly. Will the following hybridize 

 or in any way lose flavor by being planted near 

 each other, and, if so, how far apart should they 

 be planted, viz.: Watermelons and citrons, water- 

 melons and muskmelons, watermelons and cucum- 

 bers, muskmelons and cucumbers, muskmelons 

 and pumpkins, muskmelons and squash, squash 

 and pumpkins, different kinds of muskmelons? 

 Also, if they do mix will the change be perceptible 

 the same year or from the seed of that in the next 

 year's fruit ? When one has only a square plot 

 and wishes to cultivate a variety it is well to 

 know. Thanking 3'ou for past favors, I am yours 

 truly, 



Iroquois, Ont. A. B. Cameron. 



The question of crossing and hybridizing 

 of cucurbits is one about which there is a 

 good deal of misunderstanding. The most 

 systematic experiments along this line hav^e 

 been conducted at the Cornell Experiment 



Station by Prof. Bailey, and results attained 

 show that hybridizing is not nearly so 

 frequent as is supposed. 



Different varietes of the same species, 

 such as one variety of muskmelon with 

 another, or one variety of cucumber with 

 another cross readily, but hybridizing, or 

 the crossing of distantly related species, 

 .such as muskmelons with pumpkins, vtry 

 rarely, if ever, occurs, although in more 

 closely related species like the watermelon 

 with the citron it is not unfrequent. 



The effect of the cross, however, is not 

 apparent the first year and shows itself 

 only in the product of the seeds of the 

 crossed specimens. In practice, therefore, 

 all of these cucurbits may be grown side by 

 side without injury or loss to quality in any 

 of them. The seed from specimens grown 

 in a mixed plantation should not be saved for 

 future planting-.

Wild Ginger. 



1 1 66. Will you kindly let me know through 

 your magazine if the enclosed leaf belongs to the 

 much valued ginseng root ? 



Fergus. F. Tobin. 



The leaf which you send is that of the 

 wild ginger {Asariim Canadense), a plant in 

 no way related to the ginseng, which 

 belongs to the Aralia family. Ginseng may 

 be easily known by the following characters : 

 The plant bears only one stem each year, on 

 the summit of which are three leaves on 

 long petioles, each leaf consisting of five 

 petioled leaflets. From the point where the 

 three leaves are borne at the summit of the 

 stem, a small umbel of greenish white 

 flowers is thrown up. Late in the season 

 these flowers are followed by bright scarlet 

 berries.
