of P. Larfcio ; the cones being only a little larger, and of a lighter colour. 

 Notwithstanding that difference, I was near regarding these two trees as 

 identical ; but the young plants raised from the seeds of P. pyrenaica have 

 induced me to alter that 

 opinion ; they differ sens- 

 ibly from those of P. La- 

 ricio, but bear a certain re- 

 semblance to those of P. 

 maritima. It becomes, then , 

 very probable, that the P. 

 pyrenaica is at least a very 

 decided variety of P.Laricio. 

 I suspect that it will be 

 found identical with the Ca- 

 labrian pine [P. L. calabrica 

 Art. Brit.]. At all events, 

 it is evidently an interest- 

 ing tree to study, and to 

 follow up." 



Multiplying Tree Peonies 

 by grafting. — Plants of the 

 JPsebnia Moutan, raised by 

 cuttings, remain weak for 

 several years; but those 

 grafted on the tubers of 

 the herbaceous peony grow with vigour, and, if permitted, will flower the fol- 

 lowing spring. The operation of grafting is performed between July 13. and 

 August 13., and will readily be understood by Jig. 25., in which a represents 



a triangular section made in the tube or stock; b, the scion, the lower end of 



which is pared off, so as to fit the triangular cavity in the stock ; and c, the 



scion fitted to the stock. It is not necessary that 



there should be more than one bud on the scion ; 



and, if a blossom bud should be chosen, it will flower 



vigorously the following spring. In two or three 



years the scion will throw out roots, and become 



independent of the stock. This mode of propagat- 

 ing was invented by M. Soulange Bodin, who, after 



grafting, places the plant in a pot, plunges it in heat, 



and covers it with a bell-glass. By September the 



scion has united itself to the stock ; and in Octo- 

 ber, the stock throws out roots, and the plant may 



be removed to a green-house or frame. Mr. Masters 



of Canterbury has adopted this mode of propagating, 



with this difference, that, after grafting, the graft being 



tied with bast, and covered with grafting-wax, the 



whole is inserted into a bed of tan, leaving only 



about half an inch of the point of the scion above the 



surface. The grafted plants are inserted in the 



angular interstices between the pots, with which the 



pit is usually occupied ; two, three, or four, are placed 



together, according to the size of the triangular 



space ; and a larger or smaller bell-glass is placed 



over them, as may be requisite. The tubers throw 



out roots by the end of September, or the beginning 



of October, and are then taken up and potted, and 



placed in a cold-frame, where they remain through 



the winter. 



The grafting-wax used for covering this graft is composed as follows : 



Burgundy pitch, lib.; black pitch, 4oz. ; rosin, 2 oz. ; yellow wax, 2 oz.
