it is necessary to tie them up to the stalk that is left. Disbud all 

 suckers from the stock, before they get too strong, by rubbing the 

 hand quickly up and down the stalk while these shoots are young. 

 "When the buds that were inserted are a year old, the old stems 

 should be cut off smoothly to heal over. 



In the propagation of plants by grafting, it is fully as necessary 

 to know the kinds of stocks to w^ork on, as it is to know how to 

 perform the operation, and while I have not the time at present to 

 speak of all the stocks used, I will give a list of the principal ones. 



The five-leaved pines, such as Cembra, parvifoUa, and others, all 

 do well on Pinus Strobus ; and on P. sylvestris (the Scotch pine) 

 and P. resinosa, all the rest of the pines will succeed. Picea 

 excelsa will do for all the spruces, while Abies pectinata and A. 

 balsamea will serve well for the Silver firs. The common arbor 

 vitte (Thuja occidentalis), and ChamcBcyparis pisifera make good 

 stocks for the Petinosporas. Almost all junipers do well on the 

 red cedar, (Juniperus Virginiana). The common hemlock 

 (Abies Canadensis) is good for all the varieties except A. Doug- 

 lasii and A. Mertensiana. On the common European larch, 

 (Larix Euro2')cea), you can graft all the varieties, excepting Pseu- 

 d'jlarix Kmmpferi. For Rhododendrons, the general stock used is 

 li. Ponticum, but P. maximum might also be used. All decidu- 

 ous Rhododendrons (Azaleas) can be grafted on P. viscosuvi or 

 P. nudiflorum. All types of Kalmia latifoUa can be worked on 

 the species. Most varieties of Amelanchier, some forms of 

 mountain ash, and Pyrus Aria and varieties, make good plants 

 when grafted on the hawthorn. All apples will thrive on seedling 

 stocks, but while Pynts Toringo and P. baccata varieties will grow 

 on the common apple, they do better on seedlings of Pyrus baccata. 

 Primus mirobakma makes a good stock for nearly all plums ; and 

 all of the flowering section do well on it, such as Prunus tomentosa^ 

 P. triloba^ etc., and I think the Peach is longer lived when worked 

 on the plum. Pyrus communis is a good stock for all species and 

 varieties of pear, except for dwarfs ; although if it were plentiful 

 enough, Pyrus betidcefolia would make one of the best of stocks for 

 pears on high light ground. The Mauetti, brier, and multiflora 

 are best for most roses. All lilacs will succeed well if grafted on 

 the privet and lilac ; but I think, if it were plentiful enough, 

 Syringa villosa would make a much better stock for them. 

 Clematises graft easily on the roots of Clematis Flammtda, and
