      PLAN OF A TEMPORARY RUDDER, FITTED AND SHIPPED AT SEA,

       ON BOARD THE H.C. STEAM-VESSEL NEMESIS.

      A Main Rudder.

       B Side view of temporary rudder, made double, (out of six spare float-boards,) so as to clasp the main rudder on each side.

       C Pigs of ballast between the floats, resting on the heel-piece.

       D Lower chain guys, which pass round the heel of the rudder, crossing it at the fore part, and leading up on each quarter, with a tackle attached to each side.

       E Chain-head guys, passing through bolts in the main rudder, and set up over the stern.

       F Strengthening pieces of iron.

      The whole apparatus was found to answer remarkably well, and, during the remainder of the voyage to the Cape, (and that a trying one,) it never got out of order, or required additional support. Indeed, it was remarked by every one, that the vessel was more easily steered than it had been before.

      But the difficulties which the Nemesis had to encounter were not yet ended. Strong breezes from the southward still prevailed, without any prospect of a speedy change; her progress was slow, and there only remained on board thirty-two tons of coal, with a little wood; nor was there any place at hand to which she could run for fuel. It was therefore resolved to stand out to sea, trusting to her canvas only. Thus her remaining fuel would be reserved for any emergency, and would suffice to ensure her being able to get into port when within a reasonable distance. A reference to the map will shew her position at this time.

      As much sail was set as she could carry, and her course was altered according to the wind. Away stood the fearless Nemesis, disdaining the land, and boldly venturing out to dare the stormy seas of those regions in the depth of winter. The heavy winds from the southward, which had so long prevailed, had baffled all the usual calculations.

      On the first day of their standing away, it became more than ever apparent that, being very light, and in fact scarcely drawing five feet and a half of water, as she was really flat-bottomed, the vessel fell so much to leeward, that she made very little progress on a wind and in a heavy sea; and, in short, that her deep moveable keels were far from sufficient to counteract this tendency. It therefore became of the utmost importance to endeavour to invent some additional means of remedying this inconvenience.

      Calling to mind his former experience on the coast of Holland, and remembering the great advantage which the flat-bottomed Dutch vessels derive from the use of their lee-boards, when sailing in light winds or close hauled, with a head sea, it occurred to the commander that something of a similar kind might be adopted on the present occasion. The officers concurred in this suggestion; and when all are animated with the same cordial and enterprising spirit, few things are found to be so difficult as they at first appear. It is the mutual reliance upon each other, in the moment of difficulty, which enables British seamen boldly and successfully to brave many perils which a moment's doubt or hesitation might render insurmountable.

      PLAN OF A LEE-BOARD USED ON BOARD THE NEMESIS.

      1 Main piece, made of birch, 4 inches by 12.

       2 Nine floats, 7 ft. 8 in. long, 11 in. broad, and 2½ thick.

       3 Two-inch plank.

       4 Iron braces, 1½ in. thick, to strengthen it.

       5 Ring-bolt to get it in and out with.

       6 Beam covered with iron, for lee-board to work on.

       7 Iron clamp, extending two feet,½ in. thick.

       8 After-guy, for tricing up.

       9 Fore ditto, to steady heel.

       10 } Upper guys.

       11 }

       N.B. The chain guys were all set up with a rope and tackle.

      The above diagram will sufficiently explain the nature of the contrivance adopted on this occasion, without the assistance of minute and tedious description. It is only necessary to remark, that in addition to the four chains which are seen in the plan, a fifth was found necessary, to keep the lee-board close to the side of the vessel. It was secured to the lower end of the lee-board at its centre, and, having then been carried across the vessel's bottom, was fastened to the opposite side by a rope and tackle.

      Gradually the breeze freshened on the subsequent days, until, at last, about the 18th, it amounted to a moderate gale, with that high and heavy sea which all who have visited the Cape will long remember, threatening, every now and then, to break on board or poop the ship; but the steady little vessel rose to it like a swan, and never shipped one heavy or dangerous sea.

      Confidence in all her qualities daily increased, and, with a strong breeze on the quarter, she was now sailing, under canvas only, at the rate of eight to nine and a half knots an hour. The lee-board was found at all times useful in making the ship stanch under sail, but as it was constructed in haste, and only with such materials as were at hand, it required to be repaired and strengthened several times.

      At length, on the 29th, being still two hundred and thirty miles from the Cape, but well down to the southward, and it appearing that there was sufficient fuel left to carry her into port, the steam was for the last time got up. On the morning of the 1st July, the remarkable land of the Table Mountain, and the conical peak to the southward of it, were well in sight. The Nemesis had made a long and tiresome voyage in the most unfavourable season of the year, and the anxiety which had been shared by all on board may well be conceived. The dangers of the Cape, at that time of year, have not been exaggerated. On the 1st July, much to the astonishment of every one at Cape Town, she was descried, late in the evening, quietly steaming into Table Bay.

      It may further be questionable, in the event of a smaller steamer being intended to be sent out, whether it would not be both safer and less expensive to send it in pieces, and have it put together, by the mechanics and engineers belonging to it, at the place where it might be destined for use, than to send it ready equipped, to make its own way to its destination by steam and canvas, with all the necessary risk.
