saws that Mr.. J. Chellew, of Gladford, Peoria
e,nn'y. is at work on machine for producing
beat bv mechanical means. Mr. Chellew
said: "Thai il is we'll know that heat was a

VS. a mechanical effect" Starting with this
Llca he went to work to construct Il machine
which would produce heat.
His first attempt was success the machine

the vibrations WAS not regular hence the low

with better machinery more heat could be pro

and went to work on Il new machine which he
calls Il thermachion, 1t being the one the writer
discovered him at work upon previous Oc-

about two feet square and three feet high and
attached to one side, like an addition, was "a
box made out of thin boilerpIate, being the
same height and width az the wooden box, and
about foot deep; in the wooden box was the

generated. The essential part of the heatpro-

heat yet attained with it is about $50 degrees.

THE TALLEsT TREE IN THE WoRID-The

in the Calaveras Grove, near Stockton, Cali

was broken off, but the trunk at the fracture
was feet IN circumference, and the height of
the tree when growing was estimated to have
been more than 500 feet. This tree. however.
