356 Propagation of Stove and Greenhouse Exotics. 



Mrs. Hovey, as being a fine white, the "largest, doublest and 

 best" of all his seedlings; it is of superb habit, with splendid 

 deep green foliage, and, if it proves a pure white, it will be 

 the greatest acquisition which has yet been made. 



In our volume for 1844, (X. p. 98,) will be found an article 

 by Mr. Pierce, upon the Prairie rose, with some remarks on 

 its employment for hedges or live fences. In that article he 

 states, that, having sown a lot of seeds for the purpose of 

 stocks, "he was not a little surprised to find that he had 

 among them twelve fine varieties of double roses." It would 

 be gratifying to amateurs to know how he procured the seed 

 by which he should be so very successful in producing these 

 double varieties; whether they were from the single Prairie, 

 or from the double varieties — or whether they had been im- 

 pregnated with other sorts. We trust Mr. Pierce will find the 

 opportunity to communicate this information, that those who 

 wish to follow up his experiments may have some guide as 

 to the best method to adopt to attam the end in view. 



To Messrs. Feast and Pierce, the Covers of the rose are 

 deeply indebted Mr Feast, we are gratified to know, has 

 received some reward for his beautiful productions. We trust 

 that Mr. Pierce, whose seedlings are fully equal to any which 

 have been raised, will, in due time, also receive that token of 

 merit which is justly his due.

There are many kinds of Exotics, such as the ilfyrtus, Tas- 

 minum, A'erium, Punica, «fcc., which succeed best by this 

 mode of propagation, and, indeed, it may be considered the 

 most certain mode of propagation by division. The great ad- 

 vantage it has over any of the other modes is, that the part 

 layered receives nourishment from its parent wliile roots are 

 being formed, whereas cuttings get no further supply than
