m of the pan by the standards T and T. These may be
made of two short pieces of a roller fitted into the holes bored
in the base; A is a block of l-in. pine with a piece of leather
tacked on one side. Four nails should be driven in the base just
outside of the edge of the pan to keep it from sliding off the
pan.

Bore a hole in the base between the two spools and pass the wire
through this hole, under the spool in the paraffin, then through a
small hole in the leather and a notch in the block A, and a notch
between the base and the pan. Tie a string around the wire between
the leather and the paraffin, making the knots so they will not
pull through the hole in the leather. This makes the wire smooth,
and by making the string tighter or looser you can regulate the
thickness of the paraffin, says Electrician and Mechanic. Place
the pan on the stove; when the paraffin is melted, pull out the
wire as needed. To keep the pan from sliding place a flatiron or
some other weight on it.

** Uses of Peat [161]

Peat is used in Germany for bedding, fodder, filter, fuel and
packing purposes.

** Scientific Explanation of a Toy [162]

In a recent Issue of Popular Mechanics an article on "The Turning
Card Puzzle" was described and illustrated. Outside of the
scientific side involved herein I describe a much better trick.
About the time when the expression "skidoo" first began to be used
I invented the following trick and called it "Skidoo" and
"Skidee," which created much merriment. Unless the trick is
thoroughly understood, for some it will turn one way, for others
the opposite way, while for others it will not revolve at all. One
person whom I now recall became red in the face by shouting skidoo
and skidee at it, but the thing would not move at all, and he
finally, from vexation, threw the trick into the fire and a new
one had to be made. Very few can make it turn both ways at will,
and therein is the trick.

Take a piece of hardwood 3/8-in. square and about 9 in. long. On
one of the edges cut a series of notches as indicated in Fig 1.
Then slightly taper the end marked B until it is nicely rounded as
shown in Fig. 2. Next make an arm of a two-arm windmill such as
boys make. Make a hole through the center of this one arm. Enlarge
the hole slightly, enough to allow a common pin to hold the arm to
the end B and not interfere with the revolving arm. Two or thr
