PROPAGATION.

The edges of the bark on each side are then 

 brought close to the scion, and the whole is bound 

 with matting, and clayed. When the stock is

large, in order that its top may be soon healed 

 over, and in case of a single graft, a, failing, two 

 others are introduced at b and c. 



5. Side-grafting. — This is a modification of 

 whip-grafting, and is performed in the same 

 manner, except that the stem or branch, instead 

 of being cut completely off, is notched to a greater 

 or less depth according to circumstances, as at b 

 (fig. 304). It is useful for supplying a branch, 

 where one is deficient, on an upright stem, as at 

 a; and for replacing the branches of a tree with 

 others of a different sort, the original being 

 allowed to remain till the grafts extend so as to 

 nearly occupy their place. With this object in 

 view, a notch is made near the stem, on the upper 

 part of the branch, as at b, and a slice is taken 

 off between the notch and the stem, as at c. The 

 graft is placed there; when it pushes, the shoot 

 must be trained horizontally, and as it extends,

any growths or spurs that are in its way, as at 

 d, should be cleared off. In the case of fruit- 

 trees, the original branch notched in this way 

 bears as well as if no such operation had been

performed, and sometimes even better. When 

 the new branch has grown to a considerable 

 extent, the original should be entirely cut off at 

 b. In supplying a branch, as at a, the scion must 

 be placed with a bud pointing outwards, and the 

 shoot proceeding from it trained in a horizontal 

 direction towards e. 



6. Herbaceous Grafting, as its name implies, is 

 applicable to plants, or parts of plants, that are 

 in an herbaceous state. It has succeeded with 

 the Melon, Cucumber, Cauliflower, Tomato, and 

 Potato; and Dr. Maclean of Colchester grafted 

 the white Silesian Beet and the red Beet on 

 each other. Dwarf species of Cactus are very 

 commonly grafted on tall ones; and Clianthus 

 Dampieri, which so often perishes under culti- 

 vation when on its own roots, grows freely if

grafted in the seedling state on a seedling of

7. Herbaceous Grafting of Resinous Trees. — This 

 has been extensively practised in the forest of 

 Fontainebleau and elsewhere in France. The 

 mode of operation, as detailed by Du Breuil 

 (Cours dUmentaire theorique et pratique d- Arbori- 

 culture), is as follows:— When the terminal shoot 

 of the stock a (fig. 306) has attained about two- 

 thirds of its length, it is cut back with a hori- 

 zontal cut to the point where it begins to lose 

 its herbaceous consistence and commences to 

 become woody. The young leaves are cut off 

 between a and d, a distance of between 2h and 

 3 ins., leaving, however, about two pairs at the 

 top d d, to attract the sap. Thus prepared, the 

 stock is split down the middle to the depth of 

 1 inch or 1J inch. The scion b is cut wedge- 

 shaped, and introduced into the split, so that 

 the commencement of the cuts on each side of 

 the scion may be nearly an inch below the top 

 of the stock. The scion should be cut at the 

 place where its consistence is similar to the part 

 of the stock where it is to be inserted. Its
