2. Broad lines can
be made, as shown in Fig. 3, or unequal widths as in Fig. 4.
[Illustration: Pencil Points and Their Work]
In Figs. 2, 5 and 6 are shown lines especially adapted for the
bookkeeper or draftsman. If one lacks the ability to draw old
English letters with a pen, the letters may be first drawn with a
carpenter's pencil (Fig. 7) and the outlines marked with ink and
finally filled in. Narrow lines are made with points cut as in
Figs. 8 and 9. A little practice with the carpenter's pencil in
making these letters will enable the student to finally produce
them with the pen used for the purpose.
** Insulating Aluminum Wire [306]
Aluminum wire plunged hot into a cold solution of carbonate of
soda becomes coated with a strong layer of oxide which forms an
excellent insulator to electricity.
** How to Build an Ice-Yacht [307]
Condensed from an article by H. Percy Ashley in Rudder.
The plans and specifications shown in the illustrations are for
making a 400-ft. class ice-yacht, having a double cockpit to
accommodate four persons. The weight of the persons in the forward
cockpit keeps the boat from rearing when in a stiff breeze.
