this relates entirely the stufng or filling with straw.
The leather being previously sewn is attached 10
the machine and the wisps of straw are forced IN WIN
regularity and with any degree of force required; the
great advantage lying in the fact that the bght OF

surface of the collar being underlad entirely by the
soft, smooth ends of the straw, all pointing regularly
In one direction. II is decidedly useful INVENTION
and is not expensive necessarily to throw the
manufacture into much fewer hands than Mt present

The Boston Railtcoy Times has figured out the result
of locking the wheels at various speeds and finds that

drags under the wheels could do to prevent It, ms
assuming that every wheel is braked or locked, which
is never the case in practice-the locomotive, the
heaviest mass in the train, being without brakes,

for about $ls each.
