Elements of plane and solid free-hand geometrical drawing, with lettering; and some elements of geometrical ornamental design, including the principals of harmonic angular ratios, etcIn three parts ..for draughtsmen and artisans; and teachers and students of industrial and mechanical drawing . 10 FREE-HAND GEOMETKICAL DEAWING. PAIRS OF AT EIGHT ANGLES. The Pairs Horizontal and Vertical. Many variations can be made, and should be, in the order ofdrawing each of the following figures. Thus the vertical linescan both be begun at top or bottom, or one in each way; also,the horizontal lines may both be begun at the left end, or rightend, or one in each way. Again, both of the vertical linesmay be drawn first, or both of the horizontal ones, or one ofeach in succession. Ex. 39. To give a more ornamental character to these simpleelements, after seeking truth pf representation, only, in the pre-ceding elementary figures, they may consist in combinations offaint and heavy lines, as shown in a part of the following fig-ureSj all of which should be made of lines from a half inch tothree or more inches long.
