If it be an old Walk, that only 

 w.nrs coitirg over, it will be fuf- 

 ticicnt to lay it two or three Inches 

 thick: But where there is Plenty 

 of this ilrong reddifli Loam, then 

 you may lay it the full Depth. 



Some skreen the Gravel too fine, 

 tut this is an Error ; if it be caft 

 into a round Heap, and the great 

 Stones only rak'd off, it will be the 

 better. 



Some are apt to lay Gravel Walks 

 too round j but this is likewife an 

 Error, becaufe they are not Co good 

 to walk upon, and befides, it makes 

 them look narrow ,• an Inch is 

 enough in a Crown of five Foot, 

 and It will be lufficient, if a Walk 

 be ten Foot wide, that it lies two 

 Inches higher in '.he Middle than it 

 does on each Side j if fifteen Feet, 

 three Inches; if twenty Feet, four; 

 and fo in Proportion. 



For the Depth of Gravel Walks, 

 lix or eight Inches may do well 

 enough j but a Foot thicknefs will 

 be fufiicient for any. 



The Month of March is the pro- 

 pereft Time for laying Gravel; it 

 13 not prudent to do it fooner, or 

 to lay Walks in any of the Winter 

 Months lefore that Time. 



Some, indeed, turn up Gravel 

 Walks in Ridges in December^ in 

 order to kill the Weeds, but this 

 is very wrong ; for beiidcs that it 

 deprives them of the Benefit of 

 them all the Winter, it does not 

 aniwer the End for which it is 

 done, but rather the contrary; for 

 tho' it does kill the Weeds for the 

 prefent, yet it adds a Fertility to 

 them as to the great future Increafe 

 of both them and Grafs. 



If conftant rolling them after 

 Rains and Froft will not effectually 

 kill the Weeds and Mofs, you fhould 

 turn the Walks in Afr'il, and lay 

 them down at the fame Time,

In order to dcftroy Worms that 

 f o i the Beauty of Gi avel or Grally 

 Walks, fome recommend the water- 

 ing them well with Water in v/hich 

 Walnut -Tree Leaves have been 

 fteep'd and made very bitter, efpe- 

 cially thofe Places moft annoy'd 

 with them ; and this, they fay, as 

 foon as it reaches them, will make 

 them come out haftily, fothat they 

 may be gather'd ; but if in the firft 

 laying ot the Walks there is a good 

 Bed of Lime-rubbifh laid in the 

 Bottom, it is the moft effectual 

 Method to keep out the Worms i 

 for they don't care to harbour near 

 Lime. 



Grounds that are gravelly and 

 fandy, ealily admit both Heat and 

 Moifture ; but they are not much 

 the better for it ; becaufe they let 

 it pafs too fbon, and fb co'ntrad: no 

 Ligature ; or elfe, if they have a 

 clayey Bottom, they retain it too 

 long, and by that Means either 

 parch or chill too much, and produce 

 nothing but Mofs or cancerous In- 

 firmities ; but if the Bottom be a 

 Gravel, and there are two Feet of 

 good Earth upon the Surface, it is 

 preferable to moft other Soils for 

 almoft any Sort of Fruit ; for tho' 

 this Soil will not produce the Fruits 

 planted thereon, fo large as a loamy 

 Soil, yet they will be much better 

 tafted, and earlier ripe.
