THE FOURTH PRACTICE. 



T'o drefs a Piece of Ground upon a Hanging or Slope-Line. 



When you meet with Ground naturally fiauted upoK 

 an eafy Rife, and would not be at the Charge of removing 

 T I G. IV. all the Earth, to reduce it to a perfed Level j you may drefs 

 it upon its natural Slope^ in fuch Manner, however^ that the 

 Rife may be fo eafy and imperceptible, as not to be difcern- 

 ed in Walking, as it may be half an Inch or an Inch in a 

 Fathom^ according to the Length of the Side ; to perform 

 which, you do thus : Fix a Stake about four Foot high out 

 ©f Ground, upon theupperm<il Part of dxe Piece, as at z^,, 

 leveling a little 



Spot for that « 3> FIG. IV- 



Purpofe ^ and 

 fix another of 

 the like Height 

 at the End B*, 

 which, is-fuppo- 

 fed ta be the 

 loweft Part of the Ground ; then plant as many Stakes as are 

 neceffary betwixt thefe two, keeping their Heads in a Line 

 with the Heads of ^and that they exceed notthe Vifual 

 Ray D D.. After which, take a Gage-Stick, or portable 

 Meafure of four Foot long, and apply it to^ all the Stakes^ 

 reducing them to the proper Height of four Foot, by earth- 

 ing them up, or digging away the Ground^ as Occafion re- 

 quires- Tnis done, make a fLopirtg Pattern-Line from to- 

 as is taught in the fecond Pradice ; and by that you 

 take away the Serpentine Surface, and correit the Inequali- 

 ty of the Ground, which fliould be laid very fmooth, accor^ 

 ding to the Slope-Line CC. 



The First Observation- 



If you would lay out the whole Ground upon a gentle 

 Slope, you perform the fame Work feveral Times through" 

 the whole Extent of it^ andfinifii it by Pattern-Lines and
