This point, whichyou mark with a wooden peg where these two linescross each other, is an exact right angle from you have a peg at A, and another where thescratched lines cross. You go to A and stand behindit, and make that peg come in a line with the one at D,and this gives you the measuring line, so that you canstick pegs straight with these two, or set the gardenline, and make as long a line as youplease. This is Euclid too, andyou can also practise it at homewith pins and thread, and easiest ofall on paper on the drawing-board,with the T-square and is another way of doing it ° THE BUILDERS SQUARE. o
