TEXTBOOK OF LANDSCAPE GARDENING 
Equipment 
For practice in reading contours any contour map may be 
used. The sheets of the United States Geological Survey are es- 
pecially interesting. The pupil should go over such maps until the 
form of the land presents itself to his mind quickly and clearly as 
soon as he sees a set of contour lines, just as ideas come readily from 
reading a printed page. . 
For practice in drawing contours the pupil will require the 
usual drawing equipment, viz., drawing board, T-square, triangles, 
scales and pencils. He should also have a book of level notes, 
preferably of his own taking. 
Exercises 
Reading exercises may be given at first, but these should be 
readily understood by the pupil. At any rate the reading of con- 
tours will be more easily grasped after the pupil has had some drill 
in drawing them. 
Accordingly several exercises should be assigned in drawing 
contours on maps of various scales and kinds.
