The lead-loaded board will act as ballasl even when housed in the canoe, and will not make the canoe roll, as the greater part of the weight is tnen within 5 inches of the bottom line of the keel.

For the tame reason, most valuable help is afforded in righting the canoe when capsized, even if the board should slip back into the box or had not been lowered. A button across the slot on deck will prevent the board being unshipped in the event of the canoe turning bottom up.

Wh(;n sailing in shallow water the whole weight of the lead can be got below the keel by lowering the centerboard Sin. only.

It is much easier to handle in removing it from the canoe or putting it on board. Instead of one heavy lift of 50 pounds, you first remove 13 pounds of lead, then lift another 13, and finish with a lift of 23 pounds.

When a light centerboard only is wanted, leave the lead at home. This will in some cases save the necessity of a man keeping two centerboards.

In the accompanying drawing, at figure 1, the board is shown with one side removed, so as to bring the internal economy to view. Starting at F, the frame is continued to E, thence to D and L. It is not continued up to the top comer at C, but is taken across to M, continuing to I, it doubles back in a sort of loop, and is welded at N. This gives doubled strength at M and Bb, where the greatest strain is. The dotted line A B shows the line of the keel when the board is lowered. The portion of the frame from E to about >[ is made of bar iron ^ deep by ^^in. thick. From E to L it is chamfered off to an edge, as shown by the line R R R, so as to cut the water easily. A hook is welded on at P, which hooks on to the king bolt. "Where the sheet iron is, the frame U 4in. thick; where not covered with sheet iron—G, I, A, and F to O—it is -f thick, so as to give a uniform thickness throughout."

The sheet iron is shown by the lightly shaded part. Starting at P, its outer edge passes H, and Aa to G where it is level with tho outer edge of the centerboard. It coa-
