ICE BOATS, SLEDGES AND TOBOGGANS.

As our vacation was drawing to a close, we began to make plans for the Christmas holidays. Our previous Christmas vacation had been so completely taken up with preparations for the trip to Willow Clump Island that we had had no time for the trip itself. We resolved this time to have everything ready beforehand, so that we could spend the entire two weeks in solid pleasure. Our skate sails and snow shoes were stored in the attic, ready for use. If we were to make a trip in the snow we would need a sledge, and then, too, we wanted to make an ice boat. It would hardly pay to build these on the island and then cart them home, so it was decided to break up camp a couple of weeks before school commenced.

BREAKING CAMP.

Consequently, on the first day of September we gathered up our belongings, corraled our chickens, packed our goods, and the next day started for home. Mr. Schreiner, in response to a letter from the secretary, came down with a large wagon in which the majority of the things were packed. The rest of our luggage was stowed in the scow and the canoes, and these were towed down the canal, as before. We reached home late in the afternoon, tired and hungry. It was a treat to sit at the table again and eat some of Mother's appetizing dishes. And say, wasn't that pie great, though! My, how ravenous we were! And then a soft, comfortable bed with spotless white sheets and pillow cases. How soundly we did sleep that night! You can just bet we were all glad enough to get back to civilization, though, of course, no one could have dragged out the confession from a single one of us.

THE ICE BOAT.

School commenced on the 20th of September that year, so we hadn't much time to spare. Work was begun immediately on the ice boat. Our first ice boat was rather a crude one. A 2 by 4 inch scantling 14 feet long was used for the backbone of the boat. The scantling was placed on edge, and to lighten it and improve its appearance it was tapered fore and aft from a point 4 feet from the bow end. The thickness of the ends of the backbone was but 2 inches, as shown in Fig. 163. To the under edge of the backbone, 5 feet from the forward end, a crosspiece was nailed. This crosspiece was a 1-inch board 6 inches wide and 9 feet long. Braces were then run from the ends of the crosspiece to the forward and rear ends of the backbone, and at the rear end several boards nailed across the braces served as a seat for the boat.

Our next task was to rig up the runners. For these we used skates, which were so arranged that we could remove them whenever we wanted to. Three blocks of wood were used for the runner shoes. Two of them were cut from a 2 by 4 scantling and measured a foot in length. The third block was only 1 inch thick, but was otherwise of the same dimensions. The skates were laid face downward on the blocks with the clamping levers open; then we marked the places where the clamping jaws touched the wood and drilled holes at these points. The forward end of each block was also tapered off to fit flat against the face of the skate. Then by inserting the jaws in the holes and closing the levers, the skate was clamped to the block, just as it would be to a shoe. The two 2-inch blocks were bolted to the ends of the crosspiece, but the third block needed further attention, as it was to be used for the rudder or steering runner.

The rudder post was shaped from a block of hardwood 3 inches square and 10 inches long. Two inches from the lower end saw cuts were made in the side of the block to a depth of 3/4 inch. Then with a chisel the sides were split off, forming a large pin with a square shank 8 inches long. Next the corners of the shank were cut off, rounding it to a diameter of 1-1/2 inches. The runner block was fastened securely to the head of the rudder post with screws. A 1-1/2-inch hole was now drilled into the backbone at the stern end to receive the rudder post. A tiller was next cut out of a 1-inch board to the shape shown in Fig. 167. A slot was cut in the end of the tiller, and the latter fitted snugly over the top of the post, where it was held in place by screws threaded in through the sides.

The mast of our boat was a pole 8 feet long, tapering from a diameter 2 inches at the base to 1-1/2 inches at the top. A step for the mast was cut from a 2 by 4 block 8 inches long. A 2-inch hole was drilled into the face of this block. We had no drill large enough to bore this hole, but accomplished the same result by drilling eight 1/2-inch holes inside of a 2-inch circle (Fig. 168), and then used a chisel to cut off the projecting pieces. The mast step was firmly bolted to the backbone at its thickest part, that is, just four feet from the forward end. The mast was braced with stay ropes stretched from the top to the forward end of the backbone and to the ends of the crosspiece. A 9-foot pole, tapering from 1-1/2 inches to 1 inch in diameter, was used for the boom of the mainsail, and for the gaff we used a 6-foot pole of the same diameter.

The dimensions of the mainsail are given in Fig. 169. For mast hoops we used curtain rings. Five were attached to the sail along the luff, and one was fastened with a piece of leather to the end of the gaff. We used a different scheme for holding the boom to the mast. The forward end of the boom was flattened at the sides and a couple of cheek blocks were bolted on, forming jaws of the shape indicated in Fig. 170. The jaws were whittled out to fit nicely around the mast, and were kept from slipping off by a piece of rope passed around the mast and threaded through the ends of the cheek blocks. Half a dozen small pulley blocks were now procured, of the type used on awnings. A rope called the throat halyard was strung from the throat or forward end of the gaff through a pulley block near the top of the mast, and led down to the backbone, where it was "belayed," or wrapped around a cleat. The cleat, which was whittled out of a stick of wood, was made in the form indicated in Fig. 171. A short length of rope was strung through a pulley block and tied with some slack to the upper end and to the center of the gaff. This rope is called a "bridle," and to the pulley block on this "bridle" a rope was attached called the "peak halyard." The peak halyard was passed through a pulley block at the top of the mast, and belayed on a cleat at the side of the backbone. For the main sheet (that is, the rope used for guiding the mainsail) two pulley blocks were fastened to the backbone, one just in front of the seat and the other a few feet further forward, and two more were lashed to the boom, midway between these blocks. The sheet was fastened near the aft end of the backbone and then strung through the blocks in the order illustrated, the free end of the sheet being brought back to the seat, where a cleat was provided, to which it could be secured when desired.

The jib-sail was now cut out to the dimensions given in Fig. 172. The foot of the sail was lashed to a jib-boom 3 feet 4 inches long. The jib-boom was attached to the backbone at its fore end by means of a couple of screw eyes. The eye of one of these was pried open, linked through the other and then closed again. One of the screw eyes was now screwed into the head of the jib-boom and the other was threaded into the end of the backbone. The upper corner or "head" of the jib was tied to a jib-halyard, which passed through a block at the top of the mast, and was secured on a cleat on the backbone. On the jib we used two sheets. They were attached to the end of the jib-boom and passed on opposite sides of the mast through blocks on the crosspiece to the stern of the boat, where separate cleats were provided for them.

This completed our ice boat, and a very pretty little boat she was. It was with great reluctance that we furled the sails, unstepped the mast, and stowed away the parts in our attic until old Jack Frost should wake up and furnish us with a field of smooth ice.

THE SLEDGE.

Our sledge was patterned after a picture of one used by Peary in one of his Arctic expeditions. First we got four strips of hickory 1 inch thick, 1-1/2 inches wide and 8 feet long for the runners and side rails. Beginning 18 inches from the ends, each stick was tapered gradually to a thickness of 1/2 an inch. Then we made eight spreaders or spacing blocks, each 1-1/2 inches thick, 2-1/2 inches wide and 11 inches long. In each end a notch 1/2 inch deep was cut to receive the runners and side rails. In the edge of each block, midway of its length, a slot 1 inch deep was cut to receive the cross sticks of the sledge. First we nailed the runners and rails to the blocks, fastening them with screws, spacing the blocks 16 inches from the ends, and 20 inches apart from center to center. Then we bent the ends of the rails and runners together, fastening them with bolts, as in Fig. 175. Four crosspieces, or floor beams, were cut out of a 1-inch board, each 2 inches wide and 30 inches long. These were fitted into the slots in the space blocks and secured with screws. A cross stick was also fastened between the rails and runners at the forward end. On the floor beams we nailed a flooring of 1/2-inch slats, 2 inches wide and 6 feet long. At the rear end these slats projected 8 inches beyond the last space block and over them a cross slat was nailed. A stick of hickory 4-1/2 feet long was soaked in hot water, as described on page 39, and was bent to an U-shape. The ends were then fitted over the first cross stick, and under the first floor supports, and securely nailed in place. Another stick of hickory 6 feet long was similarly bent, and the ends slipped over the rear cross slats and fitted against the rear space blocks, in which position the stick was securely nailed.

It was our intention to shoe the runners with strips of brass, but these were not procurable in our village, and we had no time to go down to Millville. However, the village blacksmith came to our rescue and shod our sledge with sleigh runner iron.

We had planned to make two more devices for our winter sports--a toboggan and a peculiar looking contrivance called a "rennwolf," a picture of which Dutchy happened to unearth in one of his father's books. Unfortunately Bill and I had to return to school before either of these was completed. However, the work was entrusted to Reddy, who was quite handy with tools, and Jack, who was made secretary _pro tempore_, took notes on the work.

THE TOBOGGAN.

The toboggan was made of light flexible hickory boards, 1/4 of an inch thick, 6 inches wide and 8 feet long. Three of these boards were used, and they were fastened together with cross sticks or battens, about 3 inches wide and 1/2 an inch thick. There were six of these battens spaced about 15 inches apart, and secured to the floor boards with flathead screws introduced from the under side and countersunk so that the heads would not project below the bottom of the toboggan. At the forward end we screwed on a head piece of oak, 3/4 of an inch thick, 1-1/2 inches wide and 20 inches long. The head piece was fastened to the under side of the boards, so that when they were curved up into a hood it would lie on top. The ends of the head piece, which projected 1 inch each side of the boards, were notched to hold the rope, which was tied fast after the boards had been steamed. The boards were steamed by wrapping them in burlap for a distance of 2 feet from the forward end, and pouring boiling water over them, as was done with the snow shoes (page 39). Before bending the boards we had fixed screw eyes in the ends of each batten, except the forward one; a rope had been strung through these screw eyes and the ends were now tied to the head piece and drawn tight so as to bend the boards into a graceful curve. In this way the ropes were of service not only for curving the front end into a hood, but also for side rails, to hold on by when shooting swiftly around curves.

THE RENNWOLF.

The runners of the rennwolf were made of hickory strips, 1 inch thick, 2 inches wide and 8 feet long. At their forward ends these strips were tapered down to a thickness of 1/2 an inch and curved upward. About 30 inches from the rear end of each runner an upright post was nailed. The post was 3 feet long and was braced by a diagonal brace 24 inches long, as shown in Fig. 179. A tie bar was nailed to the post about 6 or 8 inches from the bottom and connected with the forward curved end of the runner.

The two runners were now placed parallel to each other about 18 inches apart, and connected by four cross bars, one at the forward end, and three on the upright posts, in about the positions illustrated. The upper cross bar was extended 6 inches beyond the posts at each side, and served as a handle for guiding the queer craft. An 18-inch square board was used for the seat of the rennwolf. It rested on the second cross-bar of the post about 12 inches from the runners, and the forward end was supported on legs nailed to the tie bars. On each runner back of the posts a loop of leather was nailed, large enough to receive the toe of one shoe.

When using this odd sled one foot would rest on the runner with the toe in the strap, and by kicking out against the snow or ice with the other foot the rennwolf would be made to spin along at a rapid rate. Of course, when coasting both feet would rest on the runners and the sled was steered by an occasional side push at the right or left. Owing to the great length of the runners the rennwolf would easily ride over uneven surfaces and thin spots in the ice.

ICE CREEPERS.

In order to provide a better hold for the propelling foot, we fastened around the toe a strap of leather, through which a number of long tacks projected. Their sharp points would stick into the ice, and prevent the foot from slipping. The seat of the rennwolf was convenient for carrying a coat or any light luggage, and it was often used to give a friend a very exhilarating ride.
