fan (rf), the wavy fan (e) ; the horizontal, with screw stem (g), and with double stem (A) 

 the vertical, with screw or wavy shoots (A), and with upright shoots ('). Haywood pro- 

 poses a sort of wavy training (Jig-, 

 387.), little different from that of 

 the wavy fan, but which is cer- 

 tainly superior to some of the other 

 of the above modes in principle, 

 as it has no tendency to constrain 

 the shoots, and produce an irregu- 

 lar distribution or exhibition of the 

 sap in gourmands, &c. (Science of 

 Horticulture, 8vo. 1818.) 



2143. Trees with flexible stems, 

 such as the vine and other climbers, 

 admit of three other varieties of 

 training (Jig. 388.), which, as 

 vines bear the sweetest fruit at the 

 greatest distance from the root, is 

 particularly suitable for them. 



2144. Fan training, as the name 

 imports, directs the spreading out 

 of all the branches like the spokes 



of the fan : it is reckoned of universal application and peculiarly suitable for peaches 

 and other stone-fruits.

2145. Horizontal training is that in which, from a main stem, lateral branches are led 

 out horizontally on each side, and is more especially adapted for pear-trees. 



2146. Horizontal training 

 uith the screw stem is chiefly 

 applicable to pears and apples, 

 and the use of the screw is to 

 cause buds to push at proper 

 places for the horizontal 

 shoots. Where this is not 

 adopted, the annual heading 

 down of the vertical shoot is 

 resorted to, by which the same 

 effect is produced; but the tree 

 requires in this case a longer 

 period to fill the wall . It may 

 be effected either with one or 

 two main stems ; but, in ge-
