PLATE 17

Whenever I have made a sketch of this kind it has always given great

pleasure to the children, and proved of more or less value in history,

or in story-telling in the lower grades.

Stroke 1 illustrates the treatment for the sky and the horizon. A few

soft touches with the side of the chalk will indicate clouds. Blend

the white tone into the gray of the blackboard. The chalk is held

vertically and drawn across the board horizontally.

Next erase a spot or two for the sails and hull of the ship, and apply

stroke 2. This stroke is made by placing the chalk in an oblique

position and drawing a curving stroke downward, the end of the chalk

giving the outline of the sail. In the drawing at the left a graded

stroke was used, the eraser making the edge of the sail at the left and

the chalk at the right.

Stroke 3 is desirable in representing the ocean. It is made by placing

the chalk vertically upon the board and making a long, sweeping stroke,

accented with the upper end of the chalk. In these sketches charcoal

was used for the dark streaks in the water.

In drawing the hull of the ship, try stroke 4, using a short piece of

chalk or charcoal. The chalk is placed vertically and a curving stroke

is used with no particular accent. Add details with touches of chalk or

charcoal.
