To the Editors Of the APPEAL:

To the Editors Of the Appeal:
NEWARK, N. j., MAJ lin your
issue of April oath, last, appeared a
communication from joseph Wadly
of Greenville, Misc, on the Memphis
water question, doing great injustice,
both by reference and direct assertion,
to the Hyatt system of water purifica-
ton. Your correspondent expresses
surprise that Gen. Greene suggests our
system, because filtration removes
nothing more than the suspended
matter, and the organic matter is still
in solution. II that is true OF filters,
ii is none the less 30 OF settling basins.
The injustice OF this is not in the
statement per Sc, but in connecting it
with the Hyatt system, which is not
filtering apparatus merely, but sys-
tenn based on natural laws and scieD-
ti6c principles, and especially adapted
to removing the very organisms in
solution and microsopically minute
suspension, which Mr.. Wadly Gays
are mo- removed by ordinary filtra.
ton. We beg leave to briefly explain:
IT. firt prepares The water for filtra-
ton by process in all essential re-
spects like that bywhich nature purifes
every drop of spring or we'll water.
As water passes naturally through the
surfuce layers Of soil, it takes up more
or less OF the earth salts found every
where. These act on the impurities
in suspension and solution, changing
their forms and causing them to sd-
here to each other in fiocculent masses,
which are strained out as the water
percolates through the strata. In pre-.
cisely the same manner the Hyatt sys-
tenn, by aningenious and delicately sd.
justed apparatus, subjects the water to
similar treatment, precipitating organ
isms in solution, massing the minute
particles Of clay, and entirely tiltering
out both by mean5of a bed OF sand
a1d comminuted coke that lis not
allowed to become clogged or foul, but
is as clean aud good after years OF use
as il was when first put in.
Your correspondent further says
that "there is no advantage gained by
the process, and it is impracticable for
such quantities, while thesettling pro-
cess has proved success and at
much less ost."
Ia this statement he is diametri-
cal'y opposed to scientific men
throughout the world. Even filtra-
ton alone will take out great many
impurities that settling tanks will not.
For instance, such things as are OF
small specific gravity and never set
tie. Filtration is rapid. Settling
tanks are slow. 1t takes months for
the finest particles of clay to settle,
aud meantime the water is not i'm
proved by sanding in en- impure
state, as this is just the condition
most favorable to vegetable growth
and the production OF animalcule
In the second place, there is no ne
cessary limit to the capacity Of our
of our system. No mater how great
or how muddy the supply, we can
purify it all without interruption.
In the third place, our system is far
less expensive and far more effective
than the basins suggested. In the city
OF st. Louis in March, 1883, there were
100000 gallons of water practically
clarified as fast as it entered, by the
chemist Of the New Orleans Water
Company, for the nominal cost of less
than one-half cent per 100 gallons,
or between $40 and $50 per 100000
gallons.
We will give any reasonable and
sufficient guarantee that our system
will do the work perfectly and tatisfsc-
torily, for about one-tenth Of that sum,
including the interest on the first cost
OF our plant and all the running ex-
p,nses.
ksto the relative expense of clean
ing our filters, and keeping two or
three reservoirs clean, we need only
say that in ours this work requires no
mechanical labor. 1t is perfectly
done by the force OF the water, about
! per cent. being used for that purpose.
We do not desire to take up too
great space to set ourselves right in
this natter, bat would like to say that
we will send TO any one who desires it
a COPY OF our large circular, giving
full descriptions OF our system in all
its details, with testimonials from we'll
known and honored citizens using our
plants in your section Of the country.
Respectfully yours,
