| and are being now CONSTRUCTED ia our country
aud also "the advantages ascribsd 10 Mr.. GilbertS
balance dock CAMEL are lndispuably due also 10
the sectional dock, attached and secured The tanks
ss."
Opinion of c. E. DtLn0id, esq.
This able engineer, in letter to Mr.. Allen, speak
ing Of this plan, says: "Your exposition of the
'ure and advantages of the sectional dock Is 80 lucld
ana complete thar only express nay entire con
c"en@e IN everything you have said on the sub
Jeeti' and, further, "the sectional floating dock,
combined with basin in the manner you indicate,
may Jusuy oe viewed as one Of The trumPhs 9t mod
srn science and mechanical skin over the ruder and
more simple contrlsRnees of those who have gone
before US; and make no doubt but what il will
long receive as general prsree Oper the Stone docks
as steamships over sailing vessels and railroads
and locomotives over the primitive turnpike and
horse teams"
Opinion Of b. H. Latto6s, esq.
This able engineer in letter TO Mr. Alleu.
speaking Of this subject, says: "Your Arguments a.
show the superiority Of the sectional dock IN every
point OF view are 10 my mind, quite conclusive"
Opinion Of r. s. Broom, esq.
This able engineer, now chief engineer of the
New York and Erie Railroad, speaking Of this
plan, IN connexion with several other civil eng
neers lee. known 10 the public,) says: I'VE cheer.
iuily express our sntire confidence IN the utility
convenience, simplicity, and perfect safety OF thI5
PLAN and do not hesitate To recommend 1t TO the
government for the use Of the navy, IN our judg-
ment superior 10 an excavated stone oT any other
plan ofdock known to u.s."
Opinion Of H. a. Norris, esq.
This able engineer, in a letter to one Of the prC-
Prietors, speaking Of this plan, says 81 have exam
med the extensive floating sectional dock in thir
city, and take great pleasure in adding my humble
testimony TO the powerful array of merchants and
ship-~r'ghts who have already spoken on the sub
jeet."
The opinion Of the chief engineer of bureau Of
yards and docks has been given above.
Against this vast array Of testimony n favor OF
the sectional dock, stands almost a0nt the opinion
Of Walter X. johnson, professor Of chemistry, &c,
N favor Of the balance dock, interested in 1t.
Commodore Stewart, and very few others, who
arc evidently ignorant Of the sectional plan, aud
have probably been mised by the advocates Of the
balance dock, speak favorably Of the latter.
We WeresPectfully ask whether there is any sufficient
ground for another commission to investigate this
subject, when such helming majority Of the
scientific intelligent, and practical men Of the coun-
'ry have already given IN their testimony in favor Of
the sectional dock preferable IN all others' Where
and how could any commission be formed at all
comparable to the above Is it any reason be-
cause professor Of chemistry, &c, gets together
parcel Of glass and tin cups and boxes and lee
lures on their stability, that a commission
should be appointed, when the fact Is proved that
the two plans of dock in operation together
IN New York; that the sectional dock is preferred
by all the persons who practically dry-docksj
and that the sectional dock gets the choice of the
business, although the balance dock offers an ad
vantage OF 20 per cent. in price Of docking OF
what account are Professor Johnson's false theo-
res stability against the facts illustrated in the
sectional dock in New York, in its practical opera
tion in raising over ZOO vessels; and also against
The fact that the balance dock in Nurseries, in
France, has actually nk 10 the bottom and is totally
Ioay The most conclusive evidence from several
sources that such u disaster has occurred, can be
produced; one is contained in the following letter
from the mate OF the ship Castor, just arrived in
New York from Marseilles, viz:
Sinking and total loss Of the balance dock in Mar
seiLies.
"NEw YoRK, June 90, 1886.
"SIR In reply to your inquiries respecting the
balance floating dock lately constructed at Mar
seilIes, in France, / would briefly state that am
the mate Of the ship CASTOR, and have Just
tended to have placed our ship in this balance dock
but upon arrival at Marseilles the dock had
sunk and they were unable to raise il; and it
the opinion there that the dock would be aban-
doned without any attempt 10 raise 1t.
Respectfully yy.HYGY YGgI', corr, rppn
Marseies is confirmed by tue su,..,nva. =. L~A.-~
Morse, esq.,, merchant of that city, lately arrived
in this country in the ship Arcole Of the new liuo
of packets from New York to Marseics
We apprehend that hereafter there can be rea-
son for a commission the question Of dry-docks,
so far at least MS the balance dock is concerned.
In behalf Of the Sectional Floating Dry-dock Com
