Ordered, by The House of Commons, to be Printed,

COPY of CORRESPONDENCE between John Clare, Junior, and
the Admiralty.

No letter, dated 22d June 1854, is in the public archives at the Admiralty.

Mr. John Clare, Junior, to the Right Honourable M. F. F. Berkeley, M.P., First Commissioner of the Admiralty.

Sir,

21, Exchange Buildings, Liverpool, 23 June 1854.

THIS day is forwarded per railway, carriage paid, to your address at the Admiralty, a small box, containing models relating to improvements in shipbuilding, in conformity with Patent No. 2042, and Patent 2662 relates to the machinery for rolling and forming metal for shipbuilding purposes.

The entire frame being made of T iron, both longitudinally and vertically, will possess sufficient strength in itself, though covered with only light plates, to enable a vessel of large tonnage to carry a heavy cargo without straining, and to resist the effects of heavy weather to an astonishing extent; then the plates when tolerably light, but having either single or double flanges or ribs on them, must obtain great strength at the top and bottom.

The first thickness of planking is of teak, which, from the oleaginous nature of that description of timber, will preserve the iron from oxidation; this, bolted downwards through the flanges, also through the vertical framing, becomes one solid mass, and the frame, not having joints like timber-built ships, must unquestionably give great stability; then a layer of cork put on the teak, and diagonal planking or sheathing over that, secured with wood screws or nails, and in some places bolted right through to the longitudinal framing; then a layer of cork again, and longitudinal planking secured through vertical framing, with copper bolts, or screwed to the inner planking of teak. The joints all through may be caulked or not, and felt placed on the outside of the planking, coppered.

The thickness of planking, cork, &c., and the number of layers of cork, must be regulated according to the amount of power of resistance to shot required. The inside may be either ceiled with timber, or diagonally laid with T iron. The flanges of the plates at the joints may be riveted together longitudinally, and the sides riveted through the vertical framing, or a longitudinal and vertical frame of iron; the plates jump-jointed with the flanges, on the outside of the plates, for the timber, &c. &c.

There are various methods of carrying out this principle of shipbuilding. Of course, it must resolve itself into a question between the expense of this mode and its enhanced efficiency and serviceableness, as regards the superior resistance to shot, and much greater facilities for plugging, in case of a shot going through the vessel's side.

I have, &c. (signed) John Clare, Junior.

Mr. John Clare, Junior, to the Right Honourable M. F. F. Berkeley, M.P., First Commissioner of the Admiralty.

Sir,

21, Exchange Buildings, Liverpool, 6 November 1854.

THE loss to Her Majesty's ships' masts and spars, &c., at Sebastopol, induces me to bring under your notice the principle of the metallic spars, &c., patented by me.
