The Investigations of Weber have
shown that the curliness of hair varies
with its fiatness. The hatter it is the
more it curls. Curling irons flatten the
hair.
The total length of railroad in
Iowa is S,490 miles The number of
employees in the state is 20,30S, falling
off of nearly 1000 from the previous
year The average yearly compensa-
ton has fallen from 1891 to $3.50, the
latter figure being lower than that for
my year since 1888.
TO prevent potato eyes from shoot
ing. one of the chief obstacles in pre-
serving the vegetables, M. Schraiban,
of the French Ins.itut Agronome,
treats them with two per cent. solu-
ton of sulphuric acid. The potatoes
are kept in this for twelve hours and
then dried; this kills the power of
termination and the acid used can do
no harm, as it does not penetrate the
skin, and the amount is less than that
contained in settler water.
The Albany railway was one of the
first street railroads of the country to
adopt the freight car service. The
cars were put on the road last Sep
TENDER, and run over the line between
Albany and Troy, q distance Of seven
miles. There is a storage warehouse
at each end of the line, into which the
cars run. The freight business is
growing. and there is every reason to
suppose that it will be q very profit
able branch of the service. Trips are
made during the day every two hours,
with q couple of extra trips between
times. The two competing steam lines
have been forced to reduce their
fieight and passenger rates

Cats can get along perfectly well
without stomachs, according to expert
ments recorded in the Archives dc
| Physiologie. In one cat, which died
| forty-eight hours after its stomach had
been cut out, the esophagus was found
to have been completely united with
| the intestine. Another cat, which
weighed four pounds when It lost its
stomach, was alive and well and
weighed four pounds and half three
| months and half after the operation.

milk. but got along nicely when the
milk was mixed with yolk of egg and
