foliage or leaf growth. But in order that plants may derive the full bene- 

 fit of increased feeding power, it is necessary that the soil in which they 

 are growing should be judiciously enriched." 



L. 8. Mote states ' that vigorous grafts will impart their vigor to the 

 stocks in the apple, pear, plum, and peach. J. C. Loudon states that the 

 mountain ash is said to grow more quickly on the thorn than on its own 

 root, though the latter is the smaller plant. 



The form of a plant may also be changed by grafting. This, however, 

 is often due to increased or diminished vigor. Prof. Bailey 2 quotes the 

 familiar fact that the Bed Canada apple is usually top-worked on some 

 other variety to overcome its weak, straggling habit. The Winter Nelis 

 pear is another example. J. G. Jack 3 states that Larex occidentalis 

 grafted on L. leptolepis is less straggling in habit than when on its own 

 roots. The trees referred to are from five to seven feet high, five of them 

 seedlings and two of them grafts, in the Arnold Arboretum at Cambridge. 

 Crataegus digyna is said to lose its thorns when grafted on C. oxycantha. 

 {Gardener's Monthly, 1860, p. 30, from Revue Horticole.) 



Knight 4 says: " The form and habit which a peach tree of any given 

 variety is disposed to assume, I find to be very much influenced by the 

 kind of stock upon which it has been budded; if upon a plum or apricot 

 stock, its stem will increase in size considerably, as its base approaches 

 the stock, and it will be much disposed to emit many lateral snoots, as 

 always occurs in trees whose stems taper considerably upward." 



J. C. Loudon 5 says: "Cerasus Canadensis [Primus Americana], 

 which in a state of nature is a rambling shrub [ ?] assumes the habit of an 

 upright shrub when grafted on the common plum. " R. P. Speer says 

 (Iowa Hort. Rep., 1888, p. 440): "There is nothing so easily affected by 

 the stock as the plum. Mr. Welling went into the woods and got forest 

 plums and set them out, grafting them with Willing scions. Scarcely one 

 of them was like the original tree. " 



M. Pepin B says: Buds of Bignonia grandi 'flora, some of which were 

 taken from a natural plant, others from a specimen of Bignonia radicans, 

 were grafted on a plant of the latter species. The first graft was a trailer, 

 its wood brown. The second graft became a shrub, its wood green. 



M. Carriere 7 is said to have twice inserted grafts of Aria vestiia on 

 thorn trees growing in pots, and the grafts as they grew produced shoots 

 with bark, buds, leaves, petioles, petals, and flowerstalks all widely differ- 

 ing from those of the Aria. The grafted shoots were also much hardier 

 and flowered earlier. 



Various other changes of habit have been recorded as having taken 

 place as the result of grafting, some of which are remarkable. Sahut 

 states {Revue Horticole, 1885, p. 399) that woody species grafted on 

 herbaceous ones prolong the duration of the latter. Carrieee 8 states 

 that he grafted the tomato on the bitter-sweet {Solanum dulcamara) and 

 produced fruits upon the graft which in appearance were unchanged 

 tomatoes, but the flesh of which was more dense, sweeter, and contained
