measure. There are hour glasses
three-minute glasses, and so on; and
these several glasses are used for
many different purposes, The hour
glass is mostly used in the sick room
and in the music room. In the sick
room it is used as a guide in admin
istering medicine, With it there is no
need Of watching the clock, no doubt
about when the last dose was given, OF
anything of that sort; but when the
sand in the glass has run out the
medicine is given and the glass is
turned, and so on. In the music room
it is used for the convenience of the
teacher, and also for the guidance OF
the pupil. In the first case there is no
occasion for consulting watch or
clock. The hour glass stands there
on the piano, and it is simply turned
and set going at the beginning of the
lesson, to mark the hour with GER
tainty. 1t is used for pupils to prac1
tice by. With an hour glass in plain
view, there is no occasion for running
off to see the time, or for turning to
look at a clock in the same room.
Here, again, started at the beginning
of the lesson, the hour glass marks
the time without any doubt or uncer-
tainty, and, though the pupil may be
glad to see the last of the sand run
through, the hour glass is a time
keeper that cannot be disputed.
Half-hour glasses are put to the
same uses as hour glasses, and these
and hour glasses as well + occa-
sionally used by teachers in school or
classroOms.
Fifteen-minute glasses are used to a
limited extent for medical purposes;
and, marking this division of time, the
sand glass goes into the kitchen as
an aid to exact cooking. There are
also made ten-minute glasses, of
which a few are used for medical Pur-
poses, and this glass is also used in
the kitchen. There is a fve-minutc
glass which is largely a kitchen glass,
used to boil eggs by and for other Pur-
poses: and the three-minUte sand
glass is called an egg boiler.
Besides the sand glasses used for
these various household or domestic
purposes, there are sand glasses used
for scientific and other purposes. A
sand glass is used, for instance, when
the. log is cast from a ship; a sand
/ glass is attached to a machine made
for indicating and registering the We
locity of the wind, this method of
marking off a period of time being in
such uses more convenient than hold
ing a watch would be.

of the other large sizes, while articles
of regular sale for the purposes for
which they are used, are scarcely ar
ticles of common sale. OF these larger
sizes, there are sold in this country
some thousands annually. OF the
small glasses, such as the egg boilers,
large numbers are sold. The three
minute glasses would be found for sale
in many stores, and at wholesale they
are common articles of sale by the
gross. Of the sand glasses used for
scientific and other purposes, the num-
Der sold is again limited.
Sand glasses are made in this coun-
try, but much the greater number of
those sold here are imported from
Europe, where they are produced in
Germany, France and England. The
sand used in sand glasses is specially
prepared by thorough cleaning, in
Guiding boiling; it is baked dry and
: perhaps ground into the requisite fine
ness and uniformity, as sharp sands
a would be likely to become wedged in
! the opening between the two parts of
. the glass. The sand is introduced into
the glass through an opening left for
that purpose in the end of one of the
bulbs, that opening being then sealed.
= The right quantity in each sand glass
is secured by the very simple method
\ of timing the flow from one part of
Il the glass to the other. In glasses of
; the same size the opening between the
two bulbs, as the glasses are produced
> by the glass blower, would be approx
I imately the same, but it wouldbe prac-
tically impossible to get them abso-
> luteIy the same, and sands might vary
more or less; so each glass is filled ac-
= cording to it's requirement. There is
|, put into an hour glass, for instance,
through the opening left for that
purpose, sand enough to run through
y the opening between the bulbs in that
. particular glass one hour, as indi,
:, Gated by a clock or other timepiece;
and every glass is Individually treat

! Hour glasses and sand glasses OF
smaller sizes are manufactured in pre-
: ciseIy the same form in which they
have long been familiar to the mind
if not from actual use, at least from
pictures, as, for instance, the draw
ing of Father Time with his scythC
l. and hour glass. Many of the smaller
l. glasses for various uses are now mad,
a with cylindrical metal frames OF
/ holders, having large openings in the
a sides. through which the glass car
k be seen and the run of the sanC

a one size and ANOTHER are in fact pu

& and finish.
While the sand glass in it's variou
forms is thus commonly made to serv
some useful purpose, it is also some
times used for decorative or orna
