r should always be used as erasures
will be frequent. A specially prepared paper that has the appearance
of oiled paper can be obtained commercially and is excellent for
sketching in damp weather. It has considerable resistance to rain.
Sheets of celluloid prepared for sketching are invaluable in sketching
in the rain. These are a part of the equipment of the case of
sketching instruments supplied battalions in the regular army. These
sheets may be procured at most any dealers.

Points for Beginners to Remember

=1893.= 1. Always keep your pencils sharpened and have an eraser
handy. No one but an expert can sketch with a dull pencil.

2. Use hard pencils when learning to sketch--4H to 6H--and go over
your work afterwards with a softer pencil--2H.

3. Do not try to put down on your sketch a mass of small details that
are too small to be shown on the scale at which you are sketching. For
example, if you are making a sketch on a scale of 3 inches = 1 mile,
do not try to show each house in a row of houses; simply indicate that
there is a row of houses, by putting down several distinct
conventional signs for houses in a row; nor should you try to show
every little "cut" through which the road may run. Only use about one
sign to the inch of telegraph or telephone lines, for wire fences,
etc.

4. When first practicing sketching only plot the route over which you
walk, indicating it by a single line. When you can do this with
facility, go back over one of these plotted routes and fill in the
woods, houses, streams and the other large features.

5. The beginner should sketch the same ground several times over--at
least three or four times. Practice alone will make perfect.

6. Always try to compare your finished sketch with an accurate map of
the ground, if one is obtainable. Try to practice on ground of which
you can obtain a map.

7. Make each course (the distance you go between points where the
direction of your route changes) as long as possible.

8. Do not try to contour until you are expert at making a sketch
showing all the flat details (roads, streams, woods, houses, etc.).

9. Never try to "sketch in" the contours until you have plotted the
stream lines or the direction of the valleys, ravines, etc. The
contours are fitted to or sketched around the drainage system; not the
drainage system to the contours.

10. Always "size up" ground before you sketch it; that is, take a
general view of it, noticing the
