Should the pupil ever extend the practice of the art beyond the simple lessons we have given her, she will find, in delineating the outlines of numerous subjects presented her, the vast utility of the "practice" which we have placed before her in the foregoing examples.

Fig. 17 is half of the base of an architectural order frequently met with, called the "Doric."
