Measuring in this waywill assist greatly to correct results. The above are the direct tests for proportion, and if carefullytaken should give the correct mass of the drawing ; but for the direc-tions of lines other tests are better. It is natural to compare directions with vertical and horizontallines. A horizontal line whose ends are equidistant from the eyeappears horizontal, and is represented by a horizontal line. A ver-tical line appears vertical, and is always represented by a vertical a ruler is held horizontal, with its ends equally distant from the eye,it illustrates the appearance represented by a horizontal line in thedrawing. By looking over the ruler thus held, the apparentdirections of lines of the object may be compared with Fig. 15. TESTS. 47 A thread with a weight attached serves as a plumb-line. Byholding the plumb-line in front of the object, the lines of the objectmay be compared with the vertical. The thread may also be used,and is often better than the ruler or pencil, for the horizontal line, asit hides none of the object. Care must always be taken to hold thethread perpendicular to a line from the eye to the object. Thisposition is easiest obtained by directly facing the group, extendingthe arms equally, and holding in each hand one end of a piece ofthread about two feet long. More care must be exercised to have the thread horizontal. Thisposition can be obtained by looking only at the thread until it islevelled, when the student may look beyond it at the group. If thereare horizontal lines in the subject which are parallel to the pictureplane they will appear horizontal and will place the thread correctly;but if the horizontal lines of th
