608 New Hardij Trees 



and one broken by accident, up to the present time (Oct. 1841). 

 The size it was glazed with before was 7 in. wide by 8^ in. deep, 

 and an open space left between the panes ; and the laps were 

 I in. deep. The sacrifice of glass and plants by frost, and by letting 

 in the cold air, was considerable ; but as one of the panes 

 got broken, 1 had it replaced by two. There used to be a 

 great many broken at the bottom of this pit by the frost ; the 

 laps being all left open with a view of letting out the condensed 

 steam that run down the ribs, &c. 1 have had the whole of the 

 bottom panes taken out, cut in two, and bedded in putty ; so 

 that now 1 have rarely one broken by the frost, as there is no 

 water to congeal. This method of puttying the laps, I find, very 

 much strengthens the glass. 



1 should be glad to hear the experience of others on the 

 subject of glazing ; and I also should like very much to see 

 some remarks on the handles and fastenings of hothouse lights, 

 as almost every gardener has his own method.
