The adoption Of steel ties in place
Of wooden ones seems to be one Of the
coming reforms in railroad building in
the country. The Delaware i HudsoA
Company has decided to lay sections of
this description, and it is expected that
other roads will follow suit. 1t is said
to be more economical and permanent
and prevents the spreading of the rails,
which is now one of the leading causes
of railroad accidents.
According to English statistics there

2, 480, 900. Since the time when these
figures were taken the number of spin
dies has increased very greatly. Cotton
is becoming more and more in demand

The average level of the solid earth
has been calculated by DR.. John Murray
to be 400 fathoms below mean sea-level;
but more recent explorations show
greater ocean depths, according to DR..
H. r. Mill, and a mean sphere-level at
depth of 100 fathoms. That is,
all the land above the level, Of
1,700 fathoms beneath the sea
would have to be filed into the. greater
depths in order to give equal height to
all parts of the solid earth.
A correspondent of the American
Machinist sent to the Office OF that pub
LEGATION pair of'spectacies worn by an
operative In factory, whose task was
grinding on an emery. wheel. These
glasses show the force which particles of
emery are apt to strike the eye, and ex-
plain clearly why it is 50 difficult for the
same to be removed when once imbedded
in the eye. A trifle spent for such glasses
would prevent an immense amount of
trouble and pain, besides saving the eyes
Of the workmen. The pair here referred
to were not only cut and ground as if
subjected to sand blast, but particles of
emery seemed to have imbedded them
selves immovably in the glas&
