The letter reads: The cut on the opposite
page, representing the diluvial deposit in
which Water is obtained for the supply of the
inhabitants of this city and vicinity,
illustrates the manner by which ordinary
wells become vitiated. Such Wells being
stoned up in a stratum of gravel, in which, at
no great distance, may be found receptacles
of filth, more or less in number, the whole
stratum in process of time becoming
impregnated, first renders the water hard
and then offensive to smell and taste, as is
always the case, in all thickly-populated
towns and cities.

The advantage of boring through an
impermeable stratum into a lower bed of
gravel which affords good water must be
apparent to everyone as such wells are
permanent, and if properly constructed,
cannot be reached by any of the impurities from
above.

The undersigned having for several years been engaged in constructing such wells, (upwards
of 100 of which are in this city) and feeling the increased importance of supplying his fellow
citizens with that priceless element, "Pure Sparkling Water," and having improved tools of
his own invention for boring and drilling is confident, that with his improved FLUSH PIPE he
can made such prices as to meet the wants of all such as may call upon him for that purpose,
either at his residence, No. 215 Eastern Av., between Bond St. and Broadway or at Wells and
Miller's Iron Foundry, Cor. of President St. and Canton Avenue or who may address him
through the Post Office.

Joseph Ruppert, Baltimore Jan. 1, 1857
