The linesnecessary to complete the drawing will represent edges which areparallel to those which have already been represented and will be drawnto converge toward the same vanishing this lesson we exemplify the law that Parallel horizontal edges receding tothe left appear to converge to a vanishing point at the left of the object; thosereceding to the right appear to converge to a vanishin^g point at the right of 3U0 AET We have found also, in the drawing of the euliieal model at an angle oi iortv-five degrees, that When ike faces of a rectanyular object are turned away equally,the vanishing points are equally distant from the point nearest the observer. That pui)ils may see the convergence to left and right just as clearly as thevsaw the lines converging to a point directly in front in the avenue of trees and alsoin tlie hook witli the string, a large wooden or pasteboard cul)e may be two strings attached to each end of the near vertical edge and a single string-to each top corner to the right and left of the near vertical edge. It will requiretwo pu])ils. one at each side of the cu1)e, to liold the strings, so that another pupil]nay stand in front of the cuhe and direct the holding of the strings in such a waytliat the actual convergence to a point on eitlier side can 1)e seen 1)yhim. This exercise is merely recommended as l)eing one in which the ]mpils wouldtake great in
