Machinery is now made for the manu-

them, where lumber is cheap, might be
profitable, if the cost of shiI ment was
paid by the purchaser.
A Norwegian farmer has invented a
curious lock in which the bolt is released
by stroke from pendulum bob. The
pendulum, invisible from the outside, is
moved sufficiently by blowing sharply
several times through hole in the door,

proper time only by swinging key pen
dulum, previously adjusted, to vibrats in
unison with the lock pendulum.
Air rlows, V-shaped contrivauces, to
be placed on the front of engines of fast

front of the locomotive. The plow ex-
tends from few inches above the track
to the top of the smokestack, the sharp
edce, of course, in front. "Shoveling
fog" is common expression among rail-
road men, but piowing wind is a new
