iron fastenings for such a coping would require to be 

 much stronger than for nine-inch copings, on account 

 of the greater power which the wind would have over 

 them. {Loudon's Suhur^ban Gard, 175.) 



For wall-trees, now that glass is become so much 

 cheaper, the best of all screens may be employed, 

 viz., glazed frames, of a length extending from the 

 coping of the wall to the surface of the soil, about 

 two feet from the stems of the trees. 



There is some difference of opinion, we confess, 

 even amongst practical men, as to the propriety of 

 protection, but we can state that, after a trial of 

 manyyears, we see no reason to doabt its efficacy, 

 and could wish to see it both more generally adopted 

 and rendered more complete then we usually find it. 

 If the copings are temporary we would have them as 

 wide as we could get them, providing they could be 

 made safe. The arguments about excluding the dews 

 we regard as nothing in this case ; indeed, such are 

 as well dispensed with during the blossoming period. 

 The protection we use is a coarse canvass of an open
