II. ENCLOSING, LAYING OUT. 



the outside, there would be space for a good large wall- 

 tree between every two jams. The top, or coping, of the 

 wall, ought to consist of semicircular bricks, which 

 should be put on in the firmest and best manner, and the 

 joints well grouted or cemented. When I come to speak 

 of the manner of preserving the blossoms and young 

 fruit of wall trees from the effects of frost and other se-

 the construction of a particular part of the wall.: at present 

 it will be sufficient to add, that it ought to be made of 

 good, solid, smoothly-finished and well-burned bricks j 

 that the mortar ought to be of the best 3 that the joints 

 ought to be uniform in size and well filled with mortar ;

 month of June, in order for it to become thoroughly dry 

 in every part before the arrival of frost. In making the 

 foundation, great care must be takerwto go lower down 

 than the depth of the trenching, in order to come at the 

 solid and immoveable earth. 



31. As was observed before, the use of one half of 

 this wall, for horticultural purposes, would be lost, unless 

 wall-trees could be placed on both sides of it ; and wall- 

 trees cannot be placed on the outside, with any chance of 

 utility, unless there be an effectual fence to protect the 

 trees on that wall. I knew an old gentleman, one of whose 

 garden wulls separated the garden from a meadow, which 

 was unprotected except by a common hedge. Those 

 persons of the village who were fond of wall-fruit, who 

 had none of their own, and who were young enough to 

 climb walls, used to leave him a very undue proportion 

 of his fruit, and that not of the best quality. He, there-
