F', to swing, through the aid of a crank, J, and rod, K. Upon the two
carriers, B B', are firmly attached two hooks, M M', which move with
them. When the hook, M, approaches the extremity of the lever, F, the
latter raises it, pushes against the spring, E, and sets free the
shuttle, which, at the same moment, meets the opposite hook, _a'_, and,
being caught by it, is carried over to the other side. The same thing
happens when the carrier, B', is on its return travel, and the hook, M',
mounts the lever, F', which is then raised.

As will be seen from this description, the woof does not undergo the
least strain, and may be drawn very gently from the shuttle. Neither
does this latter exert any friction on the chain, since it does not move
on it as in ordinary looms. In this apparatus, therefore, there may be
employed for the chain very delicate threads, which, in other looms,
would be injured by the shuttle passing over them. Looms constructed on
this plan have for some time been in very successful use in Switzerland.

HOW VENEERING IS MADE.


The process of manufacture is very interesting. The logs are delivered
in the mill yard in any suitable lengths as for ordinary lumber. A steam
drag saw cuts them into such lengths as may be required by the order
