SKATE SAILS.

The duties of the secretary, as defined in the constitution which Dutchy Van Syckel drew up, were to keep a record of all the acts of the society, the minutes of every meeting, and accurate detailed descriptions of all work accomplished. Therefore, while the rest of the society was busy cutting up old sheets, levied from the surrounding neighborhood, and sewing and rigging the sails under Bill's direction, I, with pad and pencil in hand, took notes on all the operations.

THE DOUBLE SWEDISH SAIL.

Bill evolved some new types of sails which differed materially from the type described in the first chapter. One was a double sail--"the kind they use in Sweden," he explained. One of the sheets which the foraging party brought in was extra large; it measured approximately two yards and a half square. This was folded on itself, making a parallelogram seven feet six inches long and three feet nine inches wide. The sheets we had were all rather worn and some were badly torn, so that we had to make our sails of double thickness, sewing patches over the weak spots. A broad hem was turned down at each end, and heavy tape was sewed on, leaving loops as before, to attach them to the spars. This reduced the length of our sail to seven feet three inches. The end spars were spaced apart by a light pole about ten feet long, to which they were tied at the points of intersection. The spars were also braced by halyards looped over the ends of the pole in the manner indicated in the drawing (Fig. 7). It took a crew of two boys to manipulate this sail. In use, the pole of the rig was carried on the shoulders, and the sail was guided by means of ropes attached to the lower corners of the vertical spars. These ropes in nautical language are called "sheets." The boy at the rear was the pilot and did the steering, because his position behind the sail gave him an unobstructed view in all directions. When changing tack the sail was lifted overhead to the other side of the crew.

THE SINGLE SWEDISH SAIL.

Another sail of similar form, but for use of one boy only, is shown in Fig. 10. This had a height of six and one-half feet at the forward end and three feet at the rear; and its length was five feet. This sail was very satisfactory in light winds, owing to its great area. In use we found that it was very important to keep the lower edge against the leg, as indicated by the arrow. The rig was manipulated just like the double Swedish sail, lifting it over the head when it was desired to change tack.

THE LANTEEN SAIL.

The lanteen sail we found to be a very good rig. It was made in the form of a triangle, measuring eight feet on one side, seven and one-half feet on another side and six and one-half feet on the third. The six and one-half foot side was secured to a boom, and the seven and one-half foot side to a yard. The yard and boom were hinged together by a leather strap nailed on as shown in Fig. 12, and to this hinge a rope was attached, which served as a sheet. These spars were secured to a mast erected perpendicularly to the boom and intersecting the yard a little above its center. We had had some trouble with the first sails we made in keeping the base of the sail against the body, and to overcome this difficulty Bill proposed tying the bottom of the mast to the leg. This was a rather risky thing to do, as we learned later, for in case of accident it would be difficult to get clear of the sail. It was Reddy who finally solved the problem by rigging up a step for the mast. It consisted of a leather tag tied to the leg, and provided with a hole into which the bottom of the mast was fitted. To prevent the mast from slipping too far into the step the lower portion of it was whittled down, leaving a shoulder which rested on the leather. Bill later devised another step, which consisted of a wooden block (Fig. 14) strapped to the leg and formed with a shallow socket to receive the end of the mast.

THE DANISH SAIL.

But the most satisfactory sail we found to be the Danish sail, though it was not until we had served quite a long apprenticeship and sustained many pretty bad falls that we mastered the art of manipulating these sails properly. Our ideas on this sail were obtained from a French illustrated paper which Dutchy Van Syckel picked up in his father's library. This sail was formed with a topsail so arranged that it could be lowered when the wind was too strong. The dimensions of the sail as we made it are given in the drawing (Fig. 15). The top of the sail was lashed to a spar, which was connected by a short stick to another spar tied to the mainsail about eighteen inches lower down. The sail was strengthened with an extra strip of cloth along the lower spar, and the tie strings were applied in the usual way. The connecting stick, or topmast we may call it, was hinged to the lower spar by means of a short piece of leather strap, which was passed round the spar in the form of a loop and its two ends nailed to the bottom of the topmast. The topmast extended above the upper spar a short distance, and to this we fastened the flag which our society had adopted. A couple of strong cords were secured to the center spar to provide for fastening the sail onto the skater. Tied to the lower corners of the mainsail were two sticks which were used for guiding the sail when in flight.

The different methods of sailing with this rig are shown in Figs. 17-20. When sailing with the wind the skater would stand very erect, bending backward in proportion as the wind blew fresher. By inclining the sail in one direction or the other, the skater could tack to port or starboard. When moving against the wind by skating in the usual way, the body was bent forward in such manner that the sail lay horizontal, so that it would not offer a purchase for the wind.

BAT'S WINGS.

One more sail deserves mention. It was Bill's idea, and it came near to ending his career the first day he tried it. It had no spars at all, but was merely a strip of cloth of somewhat triangular shape. The upper side was tied to the head, and the two corners to the wrists, while the lower portion was tied to the ankles. This converted him into a huge white-winged bat. Bill had to try it at once, even though the rest of the sails were not finished, and a very comical spectacle he made as he flapped his wings in his endeavors to tack. When the wind was too strong for him he had merely to drop his arms and thus lower sail. At length he became tired of holding his arms out at full length, and I got him a stick to put over his shoulders and rest his arms on. But that stick was Bill's undoing, for coming around a sudden bend in the canal he caught the full force of the wind, which knocked him flat on his back before he could disentangle himself from the stick and lower sail. It took us some time to bring him back to consciousness, and a very scared lot of boys we were for a while. However, the lesson was a good one, for after that we were very cautious in experimenting with sails that had to be tied on, such as the Danish rig and the lanteen rig, before Reddy invented the mast step.

It was not until the day after Christmas that the sails were all completed, but then there was scarcely any wind blowing and we could not attempt the expedition to the island.
