The eye is given. The ground-line we draw through point A horizontally.

If theground-line were through the lowest (nearest) cornerof the raised plane, its distance below the wouldbe the same in fact, but less ia the drawing. Hence the 186 Perspective length in feet of the ( to eye) will be ableto yary. Compare Fig. 55, p. 81. No scale is stated. We are, therefore, quite free, anddraw the through A. The two we find by continuing the lines toright and left till they meet on the horizon. It will bebest to see that the yanishing parallels from these the eye enclose a right angle, as they should. The problem requires us to construct at h} a towerprecisely similar to the one shown above A. It is to bethe same in its dimensions, yet, being evidently furtheraway, we must expect diminution of size on the drawing. EY6.
