3*2 FENCES. [March* 



the quantity properly prepared, than the whole 

 unfit. 



When the objeft is merely to procure a fence* 

 it is a matter of fmall moment what fort or varie- 

 ty of ftones be ufed, provided they be durable. 

 But where the wall is to be ufed alfo as a fruit- 

 wall, we would prefer a dark- coloured tvhinstone,* 

 of clofe texture, built with black mortar, even in 

 preference to any brick wall. The mortar for 

 fuch a wall can eafily be made black, by mixing 

 foot in working it, or when the lime is in a pow- 

 dery flate. 



Circumftances and tafte muft regulate the height 

 of the wall. A fix-feet wall will, however, be 

 found the mod complete fence. The thicknefs 

 of a fix-feet wall, at the foundation, ought to be 

 twenty-four inches, and at the top eighteen. The 

 fame thicknefs at foundation and top, will anfwer 

 for a wall twelve or fifteen feet in height ; but, 

 when the wall is below fix feet in height, the 

 thicknefs may be reduced in proportion. 



In the building of the wall, care muft be taken 

 that the ftones be laid upon their beds, and fo a 

 to take band in the moft perfect manner that the 

 materials will allow. The plan of fetting ftones 

 on edge ; of building up, as it were, two fkins, 

 and filling in probably loofe ftones, with a dafh 

 of a trowel-full of mortar on their top, cannot be 

 too much execrated or guarded againft ; and no- 



thing
