Lettering for draftsmen, engineers and students; a practical system of freehand lettering for working drawings . e top is nearlyfinished in one stroke when the down-stroke is assumed,which, beginning at the initial point of the ellipse andcompleting the latter, terminates with a somewhat fullercurve then that employed in lower case g. Though Roman numerals are seldom employedon working drawings, they may sometimes be re-quired. The chief requisite is to so form them thatthey are neat in ap- ^ ^ ^^ ^^ distinguished from the Fig. 21. rest of the text. They should be of the same height as the Arabic numerals, and short horizontal strokes 14 should be used with them, as indicated in Fig. the modified forms shown in Fig. 22 it will benoticed that all the letters and numerals are based uponthe general form of the letter o, modified to suit de-mands. The second stroke of the . r is really a part of the elemen-tary ellipse, as are also the secondstroke of the n and the secondand third strokes of the m. The u is here made in two strokes— ^ the first, a down-stroke with the curve attached, and the. second a Straight down-stroke, tangent to and touchingthe curve. The numerals follow similar lines of 2 begins at the upper part in an ellipse and endsin a down-stroke, laid at an angle of 45°, turning sharplyto the right in a horizontal line. The 3 is formedwith one stroke, with its lower curve, as also that of the 5 and 6, encircling somewhat more than half of theellipse. In the 6 and 9 care must be taken to havethe curved down-strokes only tangent to the respectiveellipses, and not cutting off a portion of the latter. UPRIGHT LETTERING. Upright lettering is employed most advantageouslyfor:;reference letters, designating lines of section, andfor captions. In some instances however, it may bedeemed advisable to use uprights also for such descrip-tive matter, dimensions, etc., to which some prominence is to be given, though, as a rule, the slanting letteri
