The PraBice P a^tt^II. 



the &me Line^ which we call the Line of Aim, or Viftial 



It happens, that if the Eye be applied too near the Stick, 

 a Defea in' the {landing of the others can't be fo well per- 

 ceived, becaiife the ViiiialRay is always apt to deviate j 'tis 

 better,' therefore, to place yourfelf tliree or four Foot be- 

 yond the Ranging-Stick ; and {looping to its Height, with 

 one Eye flwt, aini with that which is open, and dire<a all 

 the other Stakes according to the Range of the fir{l, with 

 that in the Middle, and at the other End, fothat they be all 

 eover'd, and appear as one only, were there thirty of them 

 ftandmg in the fame Line. 



'Tis no way nece{rary, that the Ranging-Sticks llionld 

 ftand of equal Height in this Cafe; that is required only in 

 Leveling ; for if one Stick fland half a Foot higher than 

 another in this Work, it matters not, fo they range direft- 

 ly, and cover one another as they ought. 



In drawing upon the Ground, there is likewife need of 

 an In{lrument, called a Tracing-Staff^ which is a long flrait 

 Stick tipt with Iron at the lower End, having the Point 

 triangular, or Batted like a Cat's Tongue; with this Tracing- 

 Staff you ftrike out and deiign all the Figures of a Garden ; 

 in a Word, 'tis the very Pencil-Cafe of him that traces 

 Things upon the Ground. 



In tracing, you muft ftrain the Line from Stake to Stake^ 

 and follow ix with the Tracing-Staff, fo as not to force it, 

 one way or other : In great Lengths, it would be well to- 

 drive fmall Spikes in the Track, at proper Diftances, both 

 for fear it fliould be defaced, and alfo that it may be the 

 better diflinguifli'd at a Diflance. 



When you trace, the Earth fliould be broke up a little 

 before the Tracing-Staff, to make the Track fliew larger and' 

 deeper : You pafs the Tracing-Point feveral times through 

 the fame Track, and fometimes your Hand fide-ways, to- 

 mark it the more diftinftly, left the Wind an<i the Rain. 



Ihould deface it. , ,1 



You ought never to take up the Stakes till the Track be- 

 fcored out very plain upon the Ground, and two, at leaft,. 

 fliould be conftaxitly left in each Line, as well to be of ufe;
