Brig. Gen. THOMAS JORDAN, Chief of Staff :
GENERAL: The work on torpedo ram has nearly come to a stand for
the want of iron. I have exhausted every private source of supply,
and unless the Government comes to my assistance the work must
stop. The whole sponsiug of the boat is ready for the iron plating.
The engine is in place, and the shield is finished as far as my supply of
iron for bolts will permit. I have requested Commodore Ingraham to
assist me, but he is unable to do so. I hope the practical demonstra-
tions of the efficiency of torpedoes borne by vessels may remove any
objections arising out of the novelty of the device and the departure
from long-established custom. I would respectfully suggest that if
row-boats may carry torpedoes and sink large vessels with them with-
out damage from their own weapons, whether larger vessels may not
use them more effectually and with greater security. The naval officers
of this station, after witnessing the trial in the harbor, warmly approved
of and adopted this terrible weapon of offense.
In proof of it, the iron-clads, together with every available steamer
and small boat in the harbor, are now being prepared for their use. One
thing has been clearly and fully demonstrated, and that is that ves-
sels may be constructed impenetrable by shot and shell. There is a
limit to the power of missiles ; there is no limit to the means of resist-
ing them. If six inches of wrought iron or even steel be not a sufficient
protection nine inches may be, and so on to any thickness. Such is the
resisting strength of iron-clads above the water-line in the rare and
elastic medium of air, where comparatively little resistance is offered
to the expansive force of gunpowder. But below the water-line, in a
medium incompressible, where, consequently, the power of gunpowder
becomes far more tremendous, the iron-clad vessels are undefended, for
the reason that ordinary missiles cannot reach them. It is here, then,
with a new weapon, that they must be attacked with hope of success ;
and I believe that the one satisfactory experiment with the spar torpedo
has opened to us clearly the way to the attainment of this end. I may
appear visionary, but after the most thoughtful consideration of the
subject am free to confess that with one powerful vessel, strongly iron-
plated, modeled for great speed, and with enormous motive power, with
propellers so arranged as to enable her to turn quickly, without guns of
