Experiments on an extensive scale
have been made by the Dutch Govern
ment to ascertain the relative strength
of iron and steel girders. The
soft steel girders proved to be twenty
two per cent. and the hard steel orders
sixty-six per cent. stronger than the
iron g1rders. 1t was pretty well estab-
lished that the strength of steel girders
is about the same for the two tianges if
they are made alike in section.
The great trouble in making can
non is that if flaw occurs the entire
cannon is lost, with all the time and la
Dor spent on it TO obviate this, ma
tive of Idlewild, Allegheny County,
Pa, has patented this method: he
first bores steel tube the size of the
gun desired. Ii this tube is defective
then only that much time and labor IS
lost If it is notdesect We steel breech
is put on and then about the tube and
breech is run molten cast-iron Of STEEL
to complete the gun. The patentee
has received an offer from, the Dyna-
mite Cannon Company, in which the
is interested. He has also
been offered o.. 900 for the right to cell

A single human hair indicates
whether the air supplied in the VEN
,ilation at the Capitol at Washington is
100 moist or too dry. A PEI ectly dry
sir is put st zero. Saturated air, that
s, air carrying all the moisture it will
1old, is put at 100. The human hair
absorbs moisture, and, like rope, be-
comes shorter when wet. The differ,
.nce in length between a hair six inches
inches long when wet and the same
lair when dry is made to represent the
hundred degrees of moisture on the
lial; and the hand and pointer moves
backward, or forward as the moisture
n the air varies. Ii it becomes too dry,
more steam is thrown in; If too moist,
ess steam is allowed to escape. And
hus the atmosphere is regulated at q
wholesome point. Washington Post.
