This plate was
planned especially for arithmetic lessons, as it shows in the sketches the
various processes through which the cotton passes before reaching the retailer,
thus suggesting a number of practical problems. It may be used quite as well in
geography, history, and nature study.
1 is produced by massing a bit of chalk and then rubbing it into the desired
shape by the use of the finger tip. The pod is drawn with a short stick of
charcoal, used in the same manner as the chalk.
No. 2 shows the
stroke for the sky and horizon, and has already been described in many other
To produce the
effect shown at No. 3 use the side of a short piece of chalk, and with a rather
irregular stroke draw the twigs and stems. Accent the spots for the cotton
In the other small sketches the strokes are so
evident that they hardly need description. A white, smooth sky, erased where
the mills and chimneys appear, will produce the effect in the lowest drawing. A
little charcoal may be added for the darkest tones, a stroke of the eraser for
the smoke, and little touches of chalk for the windows.
