The process is akin to whip-grafting, only the stock is left in its entire 

 length. A slope two inches long is taken off from one side of the base of 

 the scion. On this, a tongue is raised. A strip of bark and wood is next 

 cut from one side of the stock, in length and size exactly adapted to the 

 slope on the graft ; and on it is also raised a tongue to coincide with that 

 raised on the side of the graft. These cut surfaces of the scion and stock 

 are then brought together, and their tongues adjusted, when they are to be 

 secured by wrapping them with strips of cloth dipped in melted grafting 

 wax. During the month of May or June, the buds of the graft will begin 

 to expand, but not till long after those of the stock have fully opened. 



The circulation being preserved and kept up by leaving the stock entire, 

 enables the surfaces of the graft and stock to unite ; but if the'stock be 

 shortened anterior to the occurrence of that union, the graft will rapidly 

 perish. As soon as the union has apparently formed, and is manifested by 

 the growth of the scion, the stock must be gradually cut in, but in so 

 gradual a manner as not to give the tree too severe a shock. In five years 

 time from planting the seed of the stock, I have had a fine bloom of an 

 engrafted limb of a M. soulangeana ; and at this date, though vegetation is 

 suffering from a severe drought, this graft is so abundantly supplied with 

 nutrition from the luxuriant cucumber stock, that it has formed a growth of 

 three feet in length, and is now developing a second crop of flowers. 



Cleveland, Ohio, July 31, 1854. 



Amoxg the valuable drawings of Chinese plants in the library of the 

 Horticultural Society, is one of a dark rugged root, some ten inches long, 

 and six inches wide at the broadest end, of which nothing more is known 

 than that it was obtained from the public vegetable market. There can, 

 however, be no doubt that it represents a Yam of some kind. 



According to M. Stanislas Julien, as quoted lately by M. Decaisne, a 

 Yam, called Chou-Ya, or Tchou-Yu, Tou-Tchou, Chau-Tchou, Chau-Yo, &c, 

 is universally grown in China. That of Nankin is the largest, and of excel- 

 lent quality ; another from the Chou country is still better. Its stems trail 

 on the ground, the leaves are three-lobed ; and in the autumn what are 

 called fruits, but no doubt small tubers, appear among the leaves, and even- 

 tually drop off. This is perhaps the root represented in the place referred 

 to. There are, however, many other sorts.
