No. 14. Try the poplar tree. Again the vertical line is characteristic. Indicate this. Mass the foliage as before, using a vertical rather than a horizontal stroke. Do not remove the chalk from the board until the mass of foliage is represented and remember to give a light pressure for the grays and a strong one for the whites.
It is not the greatest quantity of chalk which gives the best drawing any more than the greatest quantity of pigment in our color work which gives the best painting. Represent trunk and branches as in No. 13.

No. 15. A bit of landscape indicated by a few strokes of chalk often renders the drawing much more pleasing and at the same time suggests the environment of the tree. The lines used here are those given in No. 1, No. 9 and No. 11, and are easily represented.
