An important question has lately been dis
cussch before one OF the societies Of engineers
in England. namely. the economic possibilities
oil the generation Of electro motive force in
the coal fields and its application to industrial
centres. In defining the most economic and
practically ideal method of converting heat
into work. with the mechanical facts ut present
available. such realization must depend it is
declared, on the conversion OF the solid fuel
into gaseous condition as first prerequisite:
the abstraction Of the heterogeneous value from
the fuel and its conversion into a condition
suitable for agricultural fertilization: the direct
combustion Of such gaseous fuel in the CONF

sion or the thermlc into dynamic energy. and
finally. the TRANSFORMATION " trnnsmutation Of
this dynamic into electric energy or into cleo

A new and effective machine. working auto
mntically, has been invented for the manufac-
ture OF link betting made from sheet steel, and
is adjustable for all the different sizes. The
steel is fed from the roll or coil by an auto
matte roll feed bringing the end OF the coil
about midway on the die, when the first stroke
OF the press comes down and periorates the

At a recent meeting Of the Engineers Society
OF Western Pennsylvania. q paper was read
and discussion had on tho subject OF nickel.
from which 1t appears that the nickel deposits
at various places In the United States which
may be valuable arc in Oregon. Nevada. and
North Carolina. A trial OF the North Carolina
orc is reported as showing an average Of about
per cent Of nickel although some samples
were obtained running up to 10 per cent; the
Nevada ores are abundant in quantity and
comparatively rich. but they are arsentdes of
ores are OF the silicato class. and have not
been developed In commercial quantities; In
regard to the Welding OF nickel and steel; an
examination OF rolled sheets thus treated Is
said to reveal no evidence at the edges as TO
where the nickel ends and the steel begins,
