TW tHc ~ tmHSth"'tSt,
Ii would be well for those who put Themselves
forward as smouth for the people" to be more
particularly careful Of what they do say, than
persons who do not occupy as conspicuous Sta
tons in the public eye.
IN 'Yal8h's paper N the litl, read an extract
from the "historical and statistical account OF
BALTIMORE in which the author OF the paragraph
remarks, that the manufacturing interest is taking
deep root in the vicinity Of that city, and it is
said "that there is no equal space Of ground IN
tie u,,;oa, that has so much natural water power,
united with rs many local facilities as the circle
round Baltimore Of thirty miles radius." Then
follows Il description Of the power employed, as
follows. sIhc mill streams now drive II cotton
factories; 6 iron works; carding factory; ? pa
per mills; l chocolate mile q saw-mils, and a
large amount of mllpower unemployed" This
gives us AS mill powers employed within cir
cult of THIRTY miles radius, to which let us add
50 per cent for the mill power yet unclnp Logged
and compare it with some other parts of the
United States, where mill powers may be even
more obvious than in the vicinity Of Baltimore
engaged i'll ascertaining the amount of water
power then employed in the vicinity of Whining
ton, including the fall of water unemployed
which he found to amount to ainety-$i,r water
powers equivalent to what is usually required to
drive one pair of m-stones, of - feet diameter.
1t is to be remarked, and tits is important,
that all these ioafer po,oers aoihn ten miles Of
| Wilmington, and embraced by scn,i-crcle in
cludcd from the South West to the North East
points, going around by the North--as all the op-
posite Prints are cut off from water falls, by the
low grounds lying between the town and the
Delaware.
Here then is much greater water power with
in less space; as in the one case we have As
water powers employed, and "a unemployed,
within circle whose cord is thirty miles in
length; but near Wilmington we have 96 water
pewers, within q semi-circle whose cord is but
ten miles in length. We however have small
cause to boast, either at Baltimore or Whining
ton compared with other places in the United
States. AS for instance, the western part of the
state of Ncw-York, where on the Genesec river
alone, the fall Of water within few miles, GER
tany less than thirty inlength, along the stream,
is equivalent to $50 watcr-whcels Of Is feet di-
ameter The Gcnescc descends from the same Ia
Bile land to the Lake Ontario 334ft. i'll 36l miles,
and if the stream is equivalent in power to ten
mills (say at Rochcster) the whole number OF
mill powers on that stream alone will exceed 200.
And beside these, there are many places
,,.l,a al,unIn,,t falls Of
dependant of the immense water power OF
Niagara, which shall not attempt to calculate;
but certainly it is equivalent to some thousands.
I The following interesting table Of calculations
is extracted from the account of Major Longs
expedition to the head waters OF st. Peters Ri
cr, and to the head waters of the Mississippi
1t is but rarely that common readers meet with
document OF this kind, and therefore it is dcsi-
rable to have it preserved, and the knowledge
of it extended by publication in such way as to
render it more general.
In the opinion of the writer it would add to the
value of the maps Of the United Statcs hereafter
to be published, if some proper part of the mar
Gin was made use of 10 insert tables OF this kind,
!, Gas is the case in some instances) and doci'
ment of this nature is now the more important
and is likely to become more 50, as the desire TIC
improve ourcountry by means OF canals increases
