248 TREATISE 



If the field is difpofed in the wildernefs way, let every quar- 

 ter be bounded by a row of Poplars, at two, or two and a half 

 feet afunder ; in the heaviell: and wetteft places, let them be of 

 the Lombard kind, and in the thinner and lighter, of the white, 

 which, of all the fpecies, will make the quickeft progrefs in fuch 

 foils ; and, in order to make them yield a fpeedier fhelter, by 

 growing clofe, let them be pruned or clip'd in the lides for two 

 or three years. Thefe Poplars ought to be planted, either root- 

 ed, or from cuttings four or five feet high, if fuch can conveni- 

 ently be procured, or as near that lize as you can. If the whole 

 ground is to be planted, without being divided by walks, after 

 going round it as mentioned for the quarters, let lines of Pop- 

 lars, running from fouth to north, be planted at about a hun- 

 dred, or, in very cold expofed fituations, at eighty feet afunder. 



Th e next thing to be adverted to, is the difpofition of the 

 Planes in fuch a manner as will beft promote the growth of the 

 -other more valuable trees ; to efFecfl: which, I think every fecond 

 line ought to be of them not next the Poplars, which will fuffi- 

 ciently flicker whatever is immediately near them, but amongfl 

 the trees intended for a longer continuance. 



Th e diftance of the trees over the whole plantation, (the 

 bounding and dividing lines of Poplars excepted), I think, as a 

 jufl medium, ought to be five feet every way ; for whatever the 

 advocates for very thick planting may advance, the confequen- 

 ces arifing from it, are generally more fatal, than erring in the 

 oppoiite extreme. Plants may be too much crowded, or, what 

 the gardeners call draivn, as well as too much expofed ; and the 

 flielcer of the Plane and Poplar trees, (for the time fhall here be
