After you have decided upon the size of your council grounds, drive two stakes A and B (Figs. 363 and 365) firmly into the ground; then take a cord, clothesline, or some kind of twine (Fig. 362), and tie the ends together, thus forming a loop (Fig. 363); put the loop over the two stakes A and B; next make a marker stake C (Fig. 366), and with it draw the slack of the line taut as in Fig. 364. The ellipse is marked out as in Fig. 365. This is done by taking firm hold of the top of the stake and using care to keep the line taut while the marker walks around the ground scratching the earth with the point of the marking stick, and allowing the cord to slip smoothly across the stick while the marking is being done (Fig. 364).
