or by overlapping lines, any outside bits being cleared away with India rubber.
These exercises will test the drawing power and try the patience of the pupil, but they are worthy of all the care which can be bestowed, which in future efforts will meet with its full reward.
[Fig. 76]: Draw first the square as directed in the previous lesson, join the points A, B, C and add the short lines at E and F, proceed with the curve A B, drawing it with faint lines at first, and adding stroke upon stroke until the required depth is obtained; the curve A C is more difficult to produce, in consequence of the formation of the hand; it should, therefore, be drawn in shorter pieces, joining them together afterwards by over strokes.

[Fig. 77]: Draw the square and straight lines first, then add the curves, taking care to give the greatest fullness at the right place.
[Fig. 78]: Draw the square and straight lines, proceed with the curves, taking care to make each of the same proportion.
[Figs. 79] and [80]: The ovals contained in these figures are simply foreshortened circles, and as such forms are of frequent occurrence in sketching from objects, in bridges, wheels, ends of timber, etc., they should be carefully studied; the greatest difficulty is to turn the narrow ends, and prevent their looking like corners. For this purpose it is better to draw the short curves first, thus:
