Make the copy to be reproduced on ordinary paper with aniline ink; using a steel pen, and making the lines rather heavy so they have a greenish color in the light.  A good ink may be made of methyl violet 2 parts, alcohol 2 parts, sugar 1 part, glycerine 4 parts, and water 24 parts.  Dissolve the violet in the alcohol mixed with the glycerine; dissolve the sugar in the water and mix both solutions.

When the original copy of the writing is ready moisten the surface of the hectograph slightly with a sponge, lay the copy face down upon it and smooth down, being careful to exclude all air bubbles and not shifting the paper.  Leave it nearly a minute and raise one corner and strip it from the pad, where will remain a reversed copy of the inscription.

Immediately lay a piece of writing paper of the right size on the pad, smooth it down and then remove as before.  It will bear a perfect copy of the original.  Repeat the operation until the number of copies desired is obtained or until the ink on the pad is exhausted.  Fifty. or more copies can be obtained from a single original.

When through using the hectograph wash it off with a moist sponge, and it will be ready for future use.  If the surface is impaired at any time it can be remelted in a water bath and poured into a tray as before, if it has not absorbed too much ink.

** How to Make a Sailomobile [326] By Frank Mulford, Shiloh, N. J.

I had read of the beach automobiles used on the Florida coast; they were like an ice boat with a sail, except they had wheels instead of runners.  So I set to work to make something to take me over the country roads.

I found and used seven fence pickets for the frame work, and other things as they were needed.  I spliced two rake handles together for the mast, winding the ends where they came together with wire.  A single piece would be better if you can get one long enough.  The gaff, which is the stick to which the upper end of the sail is fastened, is a broomstick.  The boom, the stick at the bottom of the sail, was made of a rake handle with a broomstick spliced to make it long enough.  Mother let me have a sheet, which I put down on the floor and cut into the shape of a mainsail.  The wind was the cheapest power to be found, thus it was utilized; the three wheels were cast-off bicycle wheels.

I steer with the front wheel, which was the front wheel of an old bicycle with the fork left on.  The axle between the rear wheels is an iron bar which cost me 15 cents, and the pulley which raises and lowers the sail cost 5 cents.  Twenty cents was all I spent, all the rest I found.

A saw, hammer, and brace and bit were the tools used.  Slats made the seat and a cushion from the house made it comfortable, and in a week

everything was ready for sailing.

Once it was started with only my little cousin in it and I had to run fast to catch up.
