The ashes recovered are used for

coal. It is estimated that in an
ordinary household from a ton To a
ton and half of coal can be thus re-
covered from the ashes in a year.
! While recent progress in radio
telephony-the transmission OF tel
| ephone talk without wire-has been
comparatively slow, there is promise
OF steady development in some recent
tests in Europe. Voice communica-
ton has been established between
Paris and Melun. sixty miles, and
later with Marseilles, eighty miles.
The French navy authorities have re-
| ported very satisfactory results in
| talking from the Eiffel Tower in
| Paris to Dieppe. ninety-three miles.
| The British admiralty. experimenting
| between Portsmouth and ships in the
| English Channel, found wireless con-
yersation quite distinct at a distance
OF sixty miles. As a test of accuracy
| during these demonstrations. long
| lists of numerals were read into the
transmitter on board one of the beet
ships aud written down at the re-
y
| four miles away A comparison of
the records showed that 9S per cent.
OF the figures had been correctly
| transmitted. The apparatus used for

grill an egg poacher, toaster, and

cents per hour. for each grill. boiling

The flavor OF meat electrically cooked
is said to excel that of meat treated
by any other method.
For the caterpillar plague which is
having such a disastrous effect on
many of the forests of this country a
remedy is suggested by the action of
the municipal authorities of a Ger
man town. The brown nun moths
had been ravaging the trees of the
valley in which the town is situated
and many OF the densely planted
sections were threatened with de-
struetion. All ordinary measures
having proven useless 10 stem the in
vasion of the moths that lay the eggs
from which the eaterpillars We're
Matched in enormous quantities, an
electric light tap was constructed.
Lights of high power were fixed in

fans. were two powerful reneetOrs.
The whole was installed on the top
of the municipal electric plant

streams of light are thrown from the
renectors on the woods on the side
of the mountains half a mile a way.
The moths drawn by the shining
radiance. come futtering in myriads
along the broad lanes of light. As
they reach the rehectors they are
caught by the swirl of the exhaust
fans and carried down on the grip of

night the trap was put into operation
three tons of moths were caught.
Other traps of the kind are TO be

Europe whose trees are threatened
