orousy in the manufacture of salt, both
by boiling and by solar evaporation; and
at this time, have sent TO market 1900
bushels of salt of the purest quality
This Company have sunk another well
during the past summer, under the same
roof, to the depth Of SOC IT,, butt have not
vet been able to learn with what results.
Numerous other enterprises have bern
started along tho Saginaw River, aud
one at Saginaw City, and one at
Carrollton, one at Portsmouth, and one
at Bay City. According to information
received from WIN. Walker, the strength
of the brine at various depths in the Bay
City well, was as follows at 223 IT,, 3 : !;
at 289 f., 2 at 285 It., II . at 245
it,, If 9; at 256 IT,, l6 c ; at 270 it.,

IT,, 20 Q; at 480 it,, 7S9; at 4S7 IT,,
S5 2 ; at 400 IT,, 90. From this point to
the depth of 5l3 it,, it varies between
SS9 and 92 Q.

10 the foregoing brief Stateme ent Of
local facts, selected from the large stock
on hand, it may be useful, in view of the
general interest felt in the salt manuiac-
ture of our State, to append some gen
eral and comparative statements, for the
purpose of consultation and reference.
AS the addition of common salt to
pure water increases its weight, bulk for
bulk, it follows that the strength of any
brine may be known by comparing its
weight with the same bulk of pure water.
This comparative weight is It's specific
gravity. The most exact method of
asccrtaining the specific gravity of brine,
is by weighing a definite bulk of it with
q delicate balance. The most convenient
method, however, is by means Of hydro
meter, aud this is sufficiently accurate
for most practical purposes. \ hydro
meter is an instrument, generally made
Of glass, in the shape Of tube closed at
both ends with a large bulb blown in it,
and q weight attached to the lower end.
The tube is graduated above the bulb in
such manner, that, when the instru-
ment is placed in pure water, it sinks to
a mark designated 0, and when placed in
q LIQUID heavier than water, it sinks to
some mark below the first against which
is the figure which de>iQnates the true
specific gravity Of the fluid. In Beaumes
hydromcter, which is the one most used
for general PURPOSES, the figures on the
scale do not designate the specific grayl-
ty directly. The scale j, graduated from
. to some arbitrary point which reads
30 or 40 , - the intervening space
being equally or ueacly divided, so that
the specific gravity can only be known
from 1t by calculation.
The hydrometer, however, which is
most convenient for experiment, 0t4
brine, is one which marks 0 > vhrn Uu-
mcrsed in pure water, and 100 Nhou
immersed in saturated brine. ihs .u-
strument is called a salometer The
number Of degrees indicated upon the
salometer, therefore, is the percentage Of
saturation, possessed 10y the brine. We
rlav speak Of - on the salometer, or
% per cent of satuIation. IL must be
distinctly uuderEtood chat p per cent of
satuation does not mean that % per
cent Of the brine is composed OF salt
twenty-five per cent OF salt produces
zoe per cent Of saturation - and this is
25 on Bcaumc's hylromcter.
1t is apparent, therefore, that the spe-
cifc gravity of brine, the readings of
the hydromoter and salomcter, and the
per centago Of salt, are all different ex-
pressions for the same thing, which may
also be expressed by the number of gal
Ions of brine required for bushel Of salt
of 5G lbs. Here follow elaborate dcmon-
strations, tables, &C., which we omit

year 1859: Massachusetts, II, ,0Q0 bushels;

vania, 100000; Virginia, 100000;
Kentucky, 100000; Ohio, 100000

The receipts of salt at Detroit fo
1889, were 2,203 barrels, and in 1860
58,2l2 barrels. The receipts at Chicag,
in 1859 were 3l6,S91 barrels; shipments
$50 ,467, of which 4,507 barrels wer
brought into Michigan by the Southern
road, and 5, ,25S by the Central road.
