tion, and cut so as to make as flat a surface as possible under the bud shield. This 

 bud shield should be about three to three and one-half inches long, with the bud in 

 the center. The small portion of wood, which will thus be taken off with the bud 

 shield, may be removed if it slips readily. If not, it should be left in place. The 

 lower end of the shield is taken between the thumb and finger and gently inserted 

 in the incision prepared for it, pushing it up until it is held firmly in place by the 

 surrounding bark. 



"The stock must then be tied with raffia or some other soft, but strong, tying 

 material so as to prevent drying out. The cut surfaces below the actual bud are 

 usually covered with grafting wax, and the whole is then wrapped with a waxed 

 cotton bandage, beginning at the lower part and winding spirally to the top, 

 exposing only the actual bud. This method protects the bud and the wound from 

 the access of water. The bud is shaded by a short piece of bandage hung over it 

 and held in place by being laid under one of the upper strands of the spirally 

 wound bandage. 



"In about three or four weeks, if the bud remains green, the stock should be 

 lopped at a point about seven inches above the bud. Care should be taken in 

 thus cutting the stock partly off to avoid splitting downward. It should be made 

 to split upward into that portion of the stock which is to be destroyed. This 

 lopping will serve to force the bud into growth. Many other buds, on the sides of 

 the stock, will start into growth before the new bud. These must all be cut off. It 

 has not been found necessary to remove the tying and wrapping material until 

 the bud has made two flushes, and often it is not necessary at all, since the raffia 

 usually decays beneath the waxed cloth and the latter naturally expands with the 

 growth of the stock. When the bud has started into growth the top of the tree 

 may be cut off and destroyed. The stump remaining above the bud may be cut 

 off with a sloping cut close to the bud. after the latter has made three or four 

 flushes." 



Influence of Stock on Scion 



Very few experiments have as yet been made to determine the influence of 

 the stock on the scion, and it is to be hoped that this important subject will be 

 more thoroughly investigated in the near future. The following statement, by 

 Prof. Rolfs, demonstrates that the field is an interesting and important one: 



"At the present time we know very little as to the influence of the stock on 

 the scion in the various groups of mangos. In this connection I may say that I 

 have two trees of the Totafari, one tree budded on the scion of an unknown variety, 

 probably belonging to the Eleanor group. This small tree began to fruit before 

 it had been set out three years, and has been a constant fruiter and heavy bearer 

 ever since. At exactly the same time that this tree [Rolfs. P. H.. 'The Mango 

 in Florida' (Proc. Am. Pomological Society, 1911] was set out. a spring was 

 taken from that tree and inarched on a large number eleven tree. This inarch 

 has grown most remarkably and has made a good sized tree, but up to the present 

 time has shown no tendency to produce bloom. One would naturally have ex- 

 pected that when this scion was inarched on the fruiting tree, the scion would
