Draw any line k /, at right angles to a e, the bafe of the hip rafter, to cut it in any point h, put the.foot of your compafs in h, as a centre, and with the other defcribe a circle to touch af the hip rafter, to cut the bafe line a e, at g; then draw g i and g k; then the angle k g i will be the backing of the hip, as is ihevvn by the bevel at; but the belt way to work the hips is to apply a bevel to the parallel fides of the hips, as is ihewn at C, by making the other fide of the bevel parallel to a e, the bafe of the hip. Note. The fame lines will extend to any iky-light, whatever may be the form of its plan; Jf it be any polygon, to find the length of the hip rafter, draw a line through any point in its bafe at right angles to it, fo as to cut the two contiguous fides to that bafe, and on the faid point as a centre defcribe a circle to touch the hip rafter from the point where this circle cuts the bafe line, draw two lines to-meet the ends of the perpendicular line at the fides of the polygon; then the angle formed by thefe two lines will be the backing required: bat perhaps a few more examples will make it plainer than many words can. Fig. J? is a fky-light, ilanding upon a rectangular bafe, having a ridge in the middle; make d upon the ridge line equal to half the width of b; then the angle b da will be a right angle; every other requifite is the fame as directed for fig. A if thefe hips are to be mitred, the bevel at ihews the mitre. Fig. is another fky-light, ftanding alfo upon a rectangular bafe; but the hips all meet over the centre of the plan at e, and confequently the diagonals...
