The PraEtice Part II 



Bafe cut the two Poles EE', and prolong, by Stakes, alfo 

 the middle Line GGj then turning yourfelf about to a 

 Square, and fetting the Alhidade upon 90 Degrees, accor- 

 ding to the fifth Pradice, range feveral Stakes from one End 

 to the other, which fhall give the Line FF. Meafurc again, 

 upon the Plan, what Length the Parterre C ought to have, 

 which is 18 Fathom 5 take alfo half the Breadth of the great 

 Crofs-Walk HH, which being five Fathom wide, will be 

 two Fathom and a half ; this added to 1 8, the Length of the 

 Parterre C makes in all twenty Fathom and a half. Mea- 

 fure out this Length by tlie Fathom upon the Middle Line 

 GG, beginning at D, where the Liftrument was firft fetj 

 and having fixed a Point at 20 Fathom and a half beyond 

 it, as in 7, drive a Stake there ; and from this, which is cal- 

 led the Center-^Poinc, you are to fet out all your principal 

 Lines, chief Walks, and Circles about the Bafon, as alfo, 

 the Bafon icfclf. Remove the Inftrument again from D to 

 the Center 7, over which fet it very plum, and let the Bafe 

 cut the two Poles EE which are next the Building, and the 

 Stakes upon the middle Line GG, and plant divers Stakes, 

 in the fame Lin^ beyond, to the veiy End of the Garden, 

 as far as K ^ then fetting the Alhidade of the Inftrument 

 upon 90 Degrees, turning yourfelf fquare for the Crofs- 

 Walk H H, and drive Stakes in the Line of it from End to 

 End> Thefe Ranges give you the Middle Lines of your 

 great Walks, and fetting off at both Ends two Fathom and 

 a half on each Side of thefe Middle Lines, drive Stakes 

 there, and by them plant others, by which means your 

 Walks will be five Fathom wide, according to the Plan. 



This being done, take away the Inftrument, and in 

 the Center 7 fix a Pole, which you may fet a little deeper 

 into Ground, in the Place where the Stake was ; meafure, 

 with the CompafTes, upon the Plan, the Diameter of the 

 Bafon, which is fix Fathom > and taking a Cord of three 

 Fathom long, which is the half Diameter, make a Loop 

 about the Pole 7, and trace the Circle, according to the fe- 

 venteenth Praftice. After which, from the fame Center 7, 

 trace out the Walk L, which compafles the lower Part ot 

 the Bafon^ and makes the circulax Part of the Parterre C
