tbem rest upon a couple of bricks or some similar sup- 

 ports. While the pear, cherry and plum can be grown 

 best in pots, the peach and nectarine should either be 

 placed in large boxes, or planted out in a border. This 

 should be prepared to the depth of two feet and its sur- 

 face will need to be top-dressed once or twice each year. 

 If in lean-to, or three-quarter span, houses the trees may 

 be trained upon the north wall, or on trellises just beneath 

 the glass if even-span, but as a rule the pyramidal form of 

 tree will be preferable. 



During the summer, after all danger of frost is over, 

 no attention need be paid to ventilating the houses, the 

 full air being left on, except when cold, chilly winds pre- 

 vail. In the winter, after the trees have ripened, the 

 sash should be handled with the idea of protecting the 

 trees from extremes of temperature, ventilation being 

 desirable on warm or bright days to prevent the swelling 

 of the buds. 



In selecting varieties of peach for forcing, only 

 those of high quality should be taken. Early Rivers, 

 George IV, Mountain Eose, Grosse Mignonne, Old- 

 mixon. Early and Late Crawford, Foster and Elberta 

 being among the best sorts for the purpose. Any of the 

 better varieties of apricots and nectarines can be used, 

 and any of the pears that succeed on dwarf stocks, such 

 as Souvenir du Congres, Louise Bonne (Fig. 89), 

 Angouleme and Anjou, will give satisfaction. Among 

 the plums the choice should be made from among the 

 Gage (Fig. 90) varieties and such other sorts as Dia- 

 mond, Czar, Coe's Golden Drop, Grand Duk^ «i,nd 

 Monarch.
