blowing engines and one steam pump. The general
plan aud specification Of this engine can be examined
at the Bureau of Steam Engineering.
The material, workmanship, and finish of all the
engines be the described In the spe-
cihcations for the machinery Of the soops of
the Juniata class copies of which in possession
of all the principal marine steam engine building
adjustments in the United States.
All the provisions embraced in the contracts for
that machinery to apply TO the contracts which may
be made under this advertisement. The same num-
Der of duplicate pieces; and the same quantf Of
tools instruments outfits etc. proportonaliy. 10 DO
supplied that is called for in those specifications.
The proposals TO be Endorsed proposals for Steam
Machinery" to distinguish them from other busi-
letters.
Parties are requested TO offer for any of the
above engines. or for many as they may consider
themselves able TO execute
The contract will embrace the usual conditionsa
payments will be made in the usual manner the
work progresses.
The Department reserves the right to reject any
all of the proposals that may be made under this adj
yertisement IT, in its opinion, the public interest re-
quires.
The proposal will state the name names of the
Navy-yards at which the parties intend TO furnish
the machinery; the number of engines they propose
to build the names of the parties In full and of their
sureties; the gross sum for which they propose 70
furnish the machinery erected in the vessel complete
and ready for steaming; and the time nom date OF
contract in which they will guarantee to complete
the work.
The proposals of parties win also be considered
who NAV choose 10 offer for machinery of equal
power on plans and specifications Of their own In
place of those above described. je6 eodtd
