386, PERSPECTIVE. 



centre of the picture j then, to find the other side, 

 lay off F G equal to the distance of the picture, 

 which, as before, depends upon taste only; draw 

 BG and G A perpendicular to BG, cutting the 

 horizontal line in A, the other vanishing point. 

 Draw now E A for the other side. To cut off the 

 several widths of the two sides of the house, which 

 as yet are only drawn to an indefinite extent, two 

 distance-points must be laid down, viz. one for each 

 vanishing point. To do this, extend the compass 

 from B to G, and lay the distance taken in it from 

 B to H, which will give H for the distance-point of 

 B, and which is to cut off all the divisions on the 

 side E B. Also extend the compasses from A G,, 

 and lay down A I. I is the distance-point of A, 

 and is used for transferring all divisions upon the 

 side E A, from the ground-line C E. These points 

 and lines being adjusted, the process is not much 

 different from parallel perspective ; only here, equal 

 divisions on each side of the building, as doors, win- 

 dows, diminish as they recede, in the same way as 

 on the side B E F C, PL 6. Fig. 1. Take the real 

 length of the side E L, from the same scale used for 

 laying down the horizontal line, and lay it down on 

 the ground-line from E to C, and draw C I, cutting 

 off E L for the perspective length of the building. 

 For the other side of the house, lay its width down 

 in the same manner, from E to D, and draw D H, 

 cutting off E N for the perspective width. Raise 

 the perpendiculars EM, LK, and NO, for the 

 three angles of the house. Lay the height of the 

 building upon the corner that comes to the ground- 

 line, as E M, and draw MK and M O to their several 

 vanishing points. Also lay all the heights of the 

 doors and windows, and other divisons, upon E M, 

 and draw them to the vanishing points A and B.
