Description

This historic book may have numerous typos and missing text. Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1872 edition. Excerpt: ...touching or crossing over each other, as in Fig. 3, but of small pieces, which in themselves form portions of the line to be drawn (Fig. 4). The work having proceeded thus far, is called the rough sketch; but the term rough must not be taken to mean coarse--it merely implies that the first delineation of the required form is more broad than accurate--that it gives the general form rather than the detail. This will, however, be gradually improved, and, therefore, it is necessary that the sketch should be done as lightly as possible. The sketch is now to be converted into a drawing. To do this, pass your india-rubber lightly over the pencil lines, so as to remove as much lead as possible without entirely erasing the form. In using india-rubber, it is better to rub in the direction of the lines than across them; and when there is much lead upon the paper, it is better that the friction should be rapid and light, rather than slow and heavy. The rubbing should not be backward and forward, by which the lead rubbed off the lines by the one stroke is rubbed into the paper by the next, but the action should be like planing or filing--namely, in one direction, the rubber being raised in the backward motion. The paper should at this stage present a perfectly clean appearance, with a very clear but slight trace of the form. Now, with a very fine, cleanly-cut point to your pencil, trace over the outline, avoiding all raggedness and endeavouring to get each line of the same thickness throughout. This process is called "lining-in." Having thus practised the method of drawing simple curves inclined towards the right and left sides, the example may be copied as presented in the plate, the great object to be kept in view being that the curves must...show more
