APPLES AND PEARS AS LATEEAL COEDONS 93 



brought about by training these double lateral cordons 

 under glass ridges is obvious enough. The figure (19) 

 will give some faint idea of the advantages of this new 

 , system of culture — ^they are endless ; for not only can 

 peaches, nectarines, apricots, plums, apples, and pears be 

 rescued from spring frosts, but their fruit be ripened in 

 great perfection. There is no doubt but that in some of 

 our cold and cloudy places in the north of England and 

 Scotland, where even the Ribston Pippin wUl not 

 ripen, it may be brought to perfection under the glass 

 fruit ridge. 



The figure (19) gives but one tree trained to one 

 wire ; two rows of wire may, however, be trained under 

 one glass ridge, which should be three feet sis inches 

 wide, at base, and the wires ten inches asunder. It i& 

 quite possible that this method of training to galvanised 

 wires may, in some situations, be better adapted to viae 

 culture than allowing the vines to rest on slates or 

 tiles. 



I now, by permission, copy the description of my 

 new glass fruit ridge from my article in the ' Gardener's 

 Chronicle ' for April 8, 1865, from which I have also 

 derived the plate kindly lent to me : — 



' There are no cross bars, but merely a frame three 

 feet wide at the base. On the top bar a is a groove 

 half an inch deep; in the bottom bar & is a groove 

 a quarter of an inch deep ; ' in the bars c and d, a,v& 



' An improvement on this is to have a rebate at bottom instead 

 of a groove ; the glass is more easily fitted in.
