VII., p. 249,) and the notice of Mr. Rivers's system of 

 pruning the roots of trees. The latter subject is now attract- 

 ing mucii notice in England, and we shall give an abstract, as 

 early as possible, of the different opinions advanced in rela- 

 tion to it, in various communications in the Gardcner''s Chron- 

 icle. 



The Massachusetts Horticultural Society, encouraged by 

 the success which attended the offer of the liberal premium 

 for the destruction of the rose-slug, voted a similar award to 

 the individual who should discover an effectual method of 

 preventing the curculio from injuring the plum and other fruits. 

 The Committee on Fruit, to whom the subject was refer- 

 red, have already received one communication, which was 

 read before the Society, but which has not been pubHshed. 

 As the season approaches, we trust individuals interested in 

 the cultivation of the plum, to which fruit the curculio seems 

 more particularly to wage eternal war, will try experiments 

 for the destruction of this most injurious insect. The canker 

 worm grub is now most easily, speedily, and economically 

 prevented from ascending trees, by a mixture of India rub- 

 ber, oil, and tar, a composition which retains its stickiness for 

 a long time; and also by India rubber alone, as recommended 

 by a correspondent, in our last volume, (p. 17.) The patent 

 lead troughs are expensive, and of very little use. 



Of the new fruits introduced the past year, which deserve 

 more particular notice, we may mention the Victoria, the 

 Cannon Hall IMuscat, and the West's St. Peters grapes, if the 

 latter is, in reality, different from the old St. Peters: an ac- 

 count of these varieties, by a correspondent, has already been 

 given in our last volume, (p. 423.) Plants of the Swain- 

 stone Seedling strawberry were introduced by Mr. Kenrick, 

 but with what success we have not been informed. A refer- 

 ence to our report of the Massachusetts Horticultural Socie- 

 ty's last annual exhibition will show the great number of fruits 

 which have been exhibited the past season, and among those 

 shown by Mr. Manning, the names of several new varieties. 

 In the report of the Pennsylvania Horticultural Society, (Vol. 

 VII., p. 468,) some new American gra])es are noticed. The 

 new banana, (Musa Cavendishu,) has been introduced, and 

 we saw plants of it in several collections in New York and 

 Philadelphia, last autumn, but it has not yet, we believe, fruit- 

 ed. Its compact growth, the small space it occupies in the
