uring or gaging on it with the thumb, and comparing the length of one point with another, as shown in the accompanying diagram.
To insure accuracy the pencil must be held at arm's length and at right angles to the line of vision.
Hold the pencil so that the end comes between the eye and some certain point on the object to be drawn; for in-
stance, in drawing a house, the height of the chimney might be taken as a standard of measurement. Hold the pencil upright, the top on a line with the chimney top. Now move the thumb downward until the end of the thumb comes between the eye and the bottom of the chimney. Then draw the chimney. Repeat the measuring operation, finding where the length of the chimney corresponds to other parts of the building.
That is to say, the pencil may be moved between the object and the eye and by using the chimney length as a standard, corresponding length and width thereof may be estimated.
The Scale on Which Drawings Should Be Made
One of the greatest faults of the beginner, and a very natural fault, is to draw on too small a scale. In copying from printed pictures, taken from periodicals of any kind, the beginner very naturally imitates the pictures as he sees them, not knowing that in ninety-nine cases out of a hundred the picture is the reduced reproduction of a drawing which was originally much larger than it appears in print.
It is well to vary the size of the drawing. A pupil working long on a very small scale would in time acquire a cramped style; on the other hand, a pupil working for an extended period at the blackboard would find it difficult to draw on a more minute scale.
Drawing from Models. Material for models is found in many of the familiar objects which surround us, such as balls, oranges, apples, potatoes, and small paper boxes. These should be drawn singly at first and in groups as the study progresses. Such objects present fairly dull surfaces and are therefore recommended. Objects having very glossy or shiny surfaces are to be avoided in all early practice. Models with dull surfaces present only light and shade in varying degree and cast simple shadows. Shiny surfaces receive and reflect complex lights and shades, hence the objection to their use.
Avoiding Confusion. In order not to confuse the eye of the pupil objects of a single color are best. The eye is centered then on form and outline rather than color. The simplest way to effect this when plaster casts are not available is to prepare a basin one-quarter full of whiting to which a small quantity of glue has been added and mixed with water until the consistency of cream is obtained. Then dip
