be rescued from spring frosts, but their fruit be ripen- 

 ed 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 Kibston Pippin will 

 not ripen, it may be brought to perfec- 

 tion under the glass fruit ridge. x^> 



The figure (Fig. 15) gives but one 

 tree trained to one wire ; two rows of 

 wire may, however, be trained under 

 one ridge, which should be three feet 

 wide at base, and the wires ten inches 

 asunder. It is quite possible that this 

 method of training to galvanized wires 

 may, in some situations, be better 

 adapted to vine culture than allowing 

 the vines to rest dh slates or tiles. 



I now, by permission, copy the de- 

 scription 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, h, is a groove a 

 quarter of an inch deep ;' in the end bars, c and d, are 

 grooves half an inch deep. The pieces of glass, which 

 should be cut so as to fit, are pushed into the upper 

 groove, and let fall into the lower one when all are 



1 An improToment on this is to haye a rebate at bottom instead of a groove ; the 

 glass is more easily fitted in.
