GARDEN MANAGEMENT. 



better method of forming curved lines than that described by Mr. Alexander 

 Forsyth, in the first volume of the London Garde7iers' Magazine. To form 

 a volute with numerous spaces .-—Make a circle around the centre of your 

 intended volute, as much in circumference as you intend the breadth of your 

 circuitous border to be. Stick the circumferential line full of pegs, and tie 

 one end of a garden-line to one of them ; then, taking the other in your 

 hand, go out to the point where you intend the volute to begin, and, as you 

 circumambulate, holding the line strained tight, you will delineate on the 

 ground the figure required. To form the spiral line where the border is 

 narrower, towards the centre, like the shell of a snail :— Make a circle as 

 before, and, instead of driving the pegs upright, let them form a cone ; or, 

 instead of pegs, use a large flower-pot whelmed, and, if necessary, a smaller 

 one whelmed over it. Measure the radius of your volute, and wind that 

 complement of Hne round the cone in such a manner as to correspond with 

 the varying breadth of your intended border, and commence making the 

 figure at the interior by unwinding the line. 



267. The following description of how to form an egg-shaped figure is from 

 Mcintosh's "Book of the Garden." The lineal 

 being given, divide it into two equal parts ; from 

 the point c, where these lines intersect each other, 

 construct a circle with the radius ca or cb ; draw 

 the line cd perpendicular to ab ; taking a and b as 

 centres, describe two arcs ; draw a line from b 

 through d, till it cuts the arc at/; then, with d 

 as a radius, complete the figure. The following groups frequently met with 



in gardening are given, 

 with their centres indi- 

 cated, to facilitate their 

 easy transference to the 

 ground. They are copied 

 by Mr. Mcintosh from a German work entitled " Handbibliothek fiir Gartner," 

 by Ligilir, of Berlin. 



368. The plan, of which the design is a quarter, 

 I would lay down by describing the entire circle 

 a, drawing the double lines inclosing the space for 

 turf or gravel at once ; then, with th^ stake still 

 at the centre, describe the circle b, and halve 

 the distance ab. Now divide the circle a into eight 

 equal parts, and draw the diagonal and straight 

 lines as in the plan, marking out the circle b, 

 and describing the elliptical and central figure ; 

 remove the compasses to the point where th© 

 diagonal lines cut the circle a, and describe the 

 semicircular lines c and d, repeating the operations on the four points, and the 

 chief part of the figure is constructed.
