56 THE FORCING GARDEN. 



the spurs are strong, when the leaders may be allowed 

 to advance until the tree is fully developed. 



The Cherry above all other fruits is liable to be in- 

 fested with the black aphides both indoors and out. 

 This pest will so infest the points of the young shoots 

 as completely to stop all further growth, but they will 

 not attack the older foliage. Now the constant nipping 

 out of the points of the young growth will be one 

 means of preventing these attacks. The remedies are, 

 to fumigate them when in the house, and when on the 

 open wall to syringe the trees with some insecticide. 



In my opinion a house planted with the May 

 Duke, Bigarreau Napoleon, or the old Bigarreau, each 

 of which bears well, would fetch from 9d. to Is. per 

 pound freely, for Cherry trees bear abundantly when 

 well managed, and many pounds may be had from one 

 of these treble cordons when it is fully developed. It 

 is seldom, however, that the best dessert Cherry trees 

 can be made to bear on open walls, but under a well- 

 constructed house an abundance of fruit may be had. 



Now suppose a house of the same dimensions as 

 the Plum-house with a back wall of the same height, 

 planted with twenty cordon Bigarreau or the May 

 Duke, and trained on this plan, they would cover the 

 wall in the course of four years and be full of fruit- 

 spurs three-fourths of the way up; and on each of 

 these treble cordons there would be in all probability 

 ten pounds of fruit, which at one shilling per pound, 

 ten shillings per tree, 10L, and say 151. for fruit from 

 the whole of the pot-trees, that would be 251. from 

 such a house, which would be a remunerative thing 

 considering the little trouble and expense, there being 

 no firing nor pots required after the first outlay. An
