One of Maine's interesting indus
tries is at Orneviue. where one concern
makes twenty different kinds OF log aud

A thermographic printing press,
capable of turning of four hundred im-
pressions an hour from hot type on
wood. is new French production. II
is said TO yield results equal TO litho.

About nine tenths OF all the clay
pipes manufactured in the United
States are made in Brooklyn, n. Y,
where three factories are located that

Two German cXperimcntcrs have
discovered that there is "A heat-centeI
located in the brain. II is found at the
front and upper part OF the brain.
When the heat-center is irritated in
rabbit, the temperature sometimes rises
several degrees, and with wonderful
quickuess.
A process, called the Cooper pro-
cess, Of lining iron pipes with glass,
is reported, which is said 90 have stood

damaging the glass. II the invention
should prove equal TO such changes OF

are faced with vitreous tile, slate OF

In the Galician forests. electric
power has been adopted Tor Telling
trees. In steam machinery for telling
trees the trunk is sawed, but in this case
il is drilled. When the wood is OF
soft nature. the drill has sweeping
motion, and cuts into the trunk by
means OF cutting edges on its sides.
The drill is actuated by an electric
motor mounted on carriage, which Is
brought up close TO the tree and
shackled TO IL. The electrical current
is conveyed 20 the motor by insulated
leads, brought through the forests from
generator placed in some convenient
site.
The manufacture of what are
termed vcneered diamonds is nota-

cut, and OF the clippings taken from
diamonds during the process Of shap-

particles Of diamonds that heretofore
have been regarded as comparatively
worthless can, by means of this in
genicus process, be made Of service 90
