In experimenting on the produc-
ton of electric currents by bending
metal wires, it is proved that the
greatest development OF current is
produced by the elongation or compress
sion of nickel wire wound in the form
Of spiral spring.

Of storage battery for similar
amount of work is $1,000. And the
latter can be maintained for about one
half the cost of keeping the horses.

Much interest is felt in the success
of the new invention of Mr.. Allen, of
Tuscaloosa, Ala, which, it is claimed,
will spin cotton from the seed, without
going through the process of ginning,
arranging the fiber, etc. 1t is apparent
that if this invention proves successful,
it will not only be an important and
valuable one in reducing the expense
of manufacturing cotton. but it will
hasten the transfer of the cotton mills
of the country to the cotton-producing
region. journal.
