Der of duplicate pieces: and the quantii of
tools, instruments, outfits, ETC. proportionaly to be
supplied, that is called for in those specifications
The proposals TO be Endorsed Proposals for Steam
Machinery" to distinguish them from other bust
ness letters.
Parties requested TO offer for any one of the
above engines or for as many as they may consider
themselves able to execute.
The contract will embrace the usual conditions and
pay ments viii be made in the usual manner as the
work progresses.
The Department reserves the right to reject any or
all of the proposals that be made under this adj
vertisement it, in its opinion, the public interest re-
qures.
The proposal will state the name or names of the
Navy-yards at which the parties intend TO furnish
the machinery; the number of engines they propose
TO build, the of the parties in full and of their
sureties the gross sum for which they propose to
furnish the machinery erected in the complete
and ready for steaming; and the time from date of
contract in which they will guarantee to complete
the work.
The proposals of parties will also be considered
who may choose to offer for machinery of equal
power on plans and specifications of their own in
