We have no doubt AN error has been
committed, in levelling, either OH the
river or for the canal but as the disa-
greemenl was not discovered until we
had gone over the whole ground, and
made the final comparison, we had not

Having carried dwelling along Craig s
creek, from lis mouth TO the mouth OF
Johns creek, then across the mountains,
and down Sinking creek TO its mouth, 90
miles, we left Bench mark on the bank
OF kana"lla. In carrying from the mouth

crossing the mountains, the vane was put
lnto new hand, and before we arrived
again al the mouth of Sinking creek. as
we passed down Greenbrier and up Ka-
nawha, | suspected that an error had
been committed at a certain place. When
we arrived again, by distance of 1873
miles, at and compared with, the mark
ut the termination OF our former dwelling,
there was disagreement. On our return
across the mountain, the suspected place
WAS examined, the error was found there,
and when this correction was applied 10
the notes, the difference of levels was but
81 inches. This proves the excellence
OF our instrument.
Finding that we had collected large
mass of materials, and that, for detail
ed exposition of The whole, many calcu-
latloms, merely technical, but of coilsi-
derabie labor, would be necessary, il was
arranged between The principal engineer
and myself, that should make most OF
the calculations which were equally es-
sential Tor both and that, as this would
OF course consume much of my time,

The canal commissioners of the state OF
New York have, in their Report of the
year 1912, exhibited calculations of the
cost OF transportation on an independent
canal the result is one cent per ton per
mile.
The laie lamented Robert Fulton, i'm a
letter TO Gouverneur Morris, now also
deceased, remarks, on those calculations
as follows:
In the Report of March, 1912, page o, the
commissioners gave calcula tions OH the ex-
pense of conveyance by canals, which calcu-
latlons were drawn from experience acquired
Oh canals i'll England as TO the quantity OF
work that two horses and three men conld do

the boat and the wages, which are higher in
this country than in England, il is shewn that
Tie total expense amounts TO NO more than

years at various canals in Eng and, TO obtain
