But before attempting either, the student should have gone over all the preceding classes several times on the slate, then with a lead pencil on paper, and lastly, with a pen and ink. Very young children may draw all the preceding figures, but it requires some maturity to draw the rest, and to apply the arithmetick.

At first the pupils should not draw the details of the frieze, capitals, &c. but merely the large and more important parts, giving them their just proportions, upon which their graceful appearance depends.

There are four modes of arranging the parts of a building, commonly called the four Orders of Architecture, viz. the Tuscan, Dorick, Ionick and Corinthian Orders.

Each has three principal parts, the Column, the Entablature which surmounts it, and the Pedestal which supports it. The pedestal is often omitted, and its place supplied by a plinth only. The order is then reduced to two parts only. Indeed, sometimes the
