CAN UTILIZE COAL WASTE

sary Patents.

Rutland, Oct. 1i.-It has been known TO
few Rutland people for some tome that
Capt Henry X. Dorr of this city had in
vented a process by which coal dust and
waste from the hard coal mines is con-
vertcd into a fuel which answers all the
purposes to which the anthracite coal of
commerce is put.
f. 5. Alberger of Buffalo, n. Y, a fuel
expert Of long experience has been sent
to Rutland to test Mr.. DORIS fuel and

named carbon fuel. was burning bright

have now been granted.
Mr.. Dorr has been at work on his in

which had accumula Ted about the mouths
Of the mines. some Of them being fully a s

product and the success OF the invention
Is now assured.
After porf"cting the anthracite fuel
Captain Dorr applied the same theory to
the bituminous coal screenings and the
result was equally successful. BY this
process bituminous fuel was produced
which gives less smoke than wood fires
and burns so completely and SO freely
