CHAPTER XIV.

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.

[Illustration: Fig. 166. The Rudder Shoe.]

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.

[Illustration: Fig. 167. The Tiller.]

[Illustration: Fig. 168. Drilling the Mast Step.]

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.

[Illustration: Fig. 169. The Mainsail.]

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.

[Illustration: Fig. 170. Jaws of the Boom.]

[Illustration: Fig. 171. A Cleat.]

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.

[Illustration: Fig. 172. The Jib-sail.]

[Illustration: Fig. 173. The Ice Boat Completed.]

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.

[Illustration: Fig. 174. A Spacing Block.]

[Illustration: Fig. 175. The Runners and Rails Spaced Apart.]

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.

[Illustration: Fig. 176. The Sledge.]

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.

[Illustration: Fig. 177. Tying Down the Head Piece of 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.

[Illustration: Fig. 178. The Toboggan.]

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.

[Illustration: Fig. 179. Dimensions of Rennwolf.]

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.

[Illustration: Fig. 180. The Rennwolf in Use.]

ICE CREEPERS.

[Illustration: Fig. 181. The Ice Creeper.]

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.
