Such a one may thus be made on rainy days or
in the long winter evenings. Procure some thin boards and construct a
small box. If it can be made pointed at one end, with two little towers
to it, so much the better. Make a glass door to it, and paste upon the
lower part of this a picture representing a scene in Spanish Germany.
Paint a rose just under the scene. Then get a lot of brass cog-wheels,
and put them together inside of the box. Arrange them so that they shall
fit into each other and wrap a string around one of them, to the end of
which a lump of lead or iron should be attached. Then put a piece of
tin, with the hours painted thereon, on the upper part of the box,
behind the door, and get two long bits of thin iron, one shorter than
the other, and connect them, by means of a hole in the middle of the
tin, with the cog-wheels inside. Then shut the door, and if this
apparatus has been properly made, it will tell the time of day. Any
thing more convenient cannot be imagined, and the cost of the brass, by
the pound, will not be more than fifteen cents, while the wood, the tin,
and the iron may be had for about ten cents.
