QUAMOCLIT QUINCE. 307 



ties of pyrus. See also Apple, Pear, Quince. It is a good 

 plan to obtain stocks as nearly related to the plant which 

 is to be propagated as possible; e. g., Parkman's pyrus 

 does better on P. floribunda than on the common apple 

 stock. The wild crabs can be worked upon the apple 

 when stocks of their own species cannot be had. 



Quamoclit. See Ipomcea. 



Quassia. Simarubacece. 



Cuttings of ripe shoots under glass. 



Quercus (Oak). Cupuliferce. 



Stocks are grown readily from seeds, which may be 

 sown in the fall without stratification. Take care that 

 vermin do not dig up the acorns. The evergreen species 

 are sometimes grown from cuttings. Varieties are grafted 

 on stocks grown from wild acorns. The stocks are potted 

 in the fall, and the grafting (generally the veneer-graft) 

 is performed in January and February, or sometimes in 

 August. 



Quince (Pyrus Cydonia, P. Cathay ensis, P. Japonica, etc.). 



Rosacece. 



All quinces can be grown from seeds, the same as ap- 

 ples and pears ; but seeds are not common in the market, 

 and are, therefore, little used. The fruit-bearing quinces 

 are propagated most cheaply by means of cuttings of ma- 

 ture wood or by mound-layering. Cuttings are taken in 

 the fall, and are stored in sand, moss or sawdust until 

 spring, when they are planted outdoors. Long cuttings 

 10 to 12 inches are usually most successful, as they reach 

 into uniformly moist earth. Cuttings are usually made of 

 the recent wood, and preferably with a heel, but wood 

 two or three years old will usually grow. With some va- 

 rieties and upon some soils, there is considerable uncer- 

 tainty, and layerage is therefore often employed. Mound- 

 layering (see page 39) is practiced where extra strong 

 plants are required. Long root-cuttings, treated like 

 those of the blackberry and raspberry, will also grow. 

 Many nurserymen bud- or root-graft the better varieties 

 upon stocks of Angers or other strong sorts. These 

 stocks are imported from Europe (and are the same as 

 those used for dwarf pears). These imported plants are 

 grown both from cuttings and mound-layers, the greater 

 part of them from the latter, but seeds are occasionally 

 employed. These stocks are two years old when im- 

 ported, having been transplanted the first year from the
