Golden Days for Boys and Girls Part 4

The covering is best made of what is known as "crash," strong and close.

It must be wide enough to go completely under the canoe, and can be had about 5 ft. wide, which will be quite wide enough. Seven yards of it will be sufficient.

To put on the canvas, turn the canoe over. Lay the canvas with the centre line along the keel. Stretch it well by pulling at each end, and tack it through the middle at the extreme ends with a few tacks in a temporary manner. Put in temporary tacks along the gunwale at moderate intervals, stretching slightly, and endeavor to get rid of all folds.

Begin in the middle and work toward the ends, and always pull straight away from the keel, and not along the gunwale. Then put in a second set of tacks half way between the first set of tacks on one side, pulling fairly tight. Then, on the other side, put in tacks opposite to the latter, pulling as tightly as possible.

The best way to do this is to seize the canvas with a pair of pincers, so that on pulling you can get the head of the pincers just over the gunwale, when they can be used as a lever to give an extra pull. A tack may then be put in on the outside of the gunwale; half-inch galvanized tacks will do.

Now remove the temporary set of tacks. To get rid of folds, which will not occur along the keel, but along the gunwale, keep bisecting the distance between two consecutive tacks by another tack, so that the canvas is equally loose on each side of it, always now pulling the canvas as tightly as possible.

In this way the folds will disappear, and the canvas be stretched tight and well-fastened to the gunwale. Leave that portion within a foot of each end untacked.

Next cut away all that portion which projects beyond the stem and stern-post; turn the edges in, and tack along the edges at moderate distances.

Bisect these distances, and these again, till you have a very close row of tacks, as in Fig. 12. Pull fairly tight, but not too tight, and do not use pincers for this part; quarter-inch tacks will be best.

The ends may be cut out and put on, lapping the edges over the side, as shown in Fig. 12, and enough canvas will be left to fill the part along the sides of the well, into which the canvas should be tacked with a fine row of tacks, afterward being stretched over the gunwale. The canoe will now be completely covered in except the well.

Before putting on the top, however, give the lower part outside a good coating of boiled linseed-oil. This will be most of it absorbed into the canvas. The same may be done afterward with the top.

When this is dry--that is, after two or three days--give another good coating of the same. Then paint the canoe according to taste. Two coats for the bottom will be advisable, and paint which will stand water well should be used. It would be well to paint the framework with one coat before covering.

[Ill.u.s.tration]

Make a stretcher (Fig. 13) for the feet, of half-inch board, and slips to fit it into (Fig. 10), with stops on the floor. Also, a backboard of half-inch board, to correspond (Fig. 14). Each piece in the latter may be 18x4 inches. They should be nailed into two cross-pieces behind, so as to form a hollow for back, and should be placed two inches apart, to allow a s.p.a.ce for the spine.

I prefer myself to fit in the backboard by means of stops on the floor and back of the well, making it keep one position, and that at a considerable slope, and have not found a swinging backboard so comfortable as some appear to have done.

For the paddle, for which I think about 7 feet 6 inches long over all is a good length, take a light, clean piece of yellow pine, or fir, 1 x 1 inches, not more, and 6 feet long. In the ends of this cut slots 6 inches long, each to receive two pear-shaped pieces of very light half-inch plank, 1 foot 3 inches by 8 inches. Nail them through with copper nails, if possible. The blades should be at right angles to the thickest direction of the handle.

Before nailing in, shave down the handle from an oval of 1 x 1 inches for 2 feet of the middle to an oval of about 1? x ? inches near the beginning of the blades.

The handle should have its full thickness at the beginning of the blade, but should be well tapered off along the blade, so as to be quite thin at its middle, where it ends. It should have its full breadth across the breadth of the blade. The blade itself may be shaved off thinner toward the edges.

I do not think that for ordinary purposes any strip of copper or tin need be put round the blade, and the weight is increased by using.

The great thing about a paddle is that it should be as light as possible, and, if it appears able to stand it, it may be reduced still further. It may be painted or varnished, all but two feet in the middle.

I find no rings on the paddles necessary.

A short strip nailed outside the gunwale in the middle of the canoe is a good thing; it prevents wear from the paddle, and forms something to catch hold of in lifting the canoe.

A short outer keel is also a good thing at each end to prevent wear; but in making holes for the nails through the canvas into the keel care must be taken to turn in the edges round each hole, to tack with a close circle of tacks, and paint well, so as to render the place water-tight.

An ap.r.o.n is seldom wanted, but may be made of canvas rendered waterproof with boiled oil, if desired.

It is well to fasten some inflated bladders in each end, so as to make the canoe a diminutive lifeboat, in case of an upset or of a hole being knocked in her.

The canoe will now be ready for launching. The owner should learn to put her carefully into the water and take her out by himself--to carry her on his shoulder.

Superfluous wood may be cut from the central parts of the shapes, and also from along the keel toward the ends before covering. The floor forms a considerable item in the weight, consequently this should be made no wider or thicker than necessary. In paddling, learn to reach well forward and back, with a good swing of the body from side to side.

Such a canoe as described will be found to wear well, and one made by myself for a friend two years ago is now in use, and quite water-tight.

HOW THE PARTRIDGE DRUMS.

"When I first came to Canada," says a writer from that locality, "I found there were various opinions as to the method of making the sound. One man, who read a great deal, but rarely went into the woods, said that the sound was produced by the bird's voice. Some of the hunters told me that the bird struck its wings on the log, and others that it struck them together over its back.

"I did not give much heed to the bookman's explanation, for all the woodmen laughed at it. I soon learned to discredit also the idea that the bird thumped the log with its wings, because whether it stood on a stump or a stone, a rotten log or solid timber, the sound was always the same. Lastly, I did not believe that the wings were struck together, because, when a pigeon or rooster strikes its wings together, the sound is always a sharp crack. At length, after watching the bird carefully, I came to the conclusion that it drums by beating the air only.

"It is not an easy matter to get sight of a partridge when he is drumming, but I managed to do it by crawling on my hands and knees toward the bird, lying still while he was quiet, and only moving forward when he renewed his noisy courts.h.i.+p; for it is only to woo and win his mate that Sir Ruffled Grouse indulges in these musical exercises.

"In this way I contrived to come within twenty feet without alarming him. Through the alder thicket I could just see his shapely form, strutting about like a turkey c.o.c.k; then for a moment he stood upright, with his feathers lying close.

"Suddenly his wings flashed, and at the same moment I heard the loud thump. Then for a few seconds he stood looking about as though nothing had happened; but presently came a second flash and thump, and others followed at lessening intervals, until at last the serenade rolled a way like the galloping of horses or the rumbling of distant thunder."

FROGS AND TADPOLES.

BY E. S.

It is very interesting in the spring to watch the gradual development of a frog from the egg, through the tadpole stage of its existence, till at last it a.s.sumes its final form.

The old frogs emerge from their winter hiding-places in the mud, early in the spring, and during April their eggs may be found floating on almost every stagnant pond.

A group of these eggs in their early stages of development looks like a ma.s.s of clear white jelly, containing numbers of black specks, each of which is really the germ of the future tadpole.

In order to watch the development, a group of the eggs should be taken and put in a shallow vessel of water, which, if kept in the house, should have a bell-gla.s.s, or some other covering, over it, to keep out the dust.

The jelly-like ma.s.s which envelopes the future tadpole is so clear that all its changes can be easily watched.

First the head appears, then a flat tail, and in course of time the nostrils, mouth and large eyes, till at length the completed tadpole bursts open its gelatinous covering, and apparently not in the least embarra.s.sed by its new surroundings, begins swimming briskly about, looking for something to eat.

The time occupied in hatching varies in different countries, according to the climate, from four days to a month.

The following stages are even more interesting, especially for those who can take advantage of the transparency of the parts to watch the circulation of the blood through a microscope.

The body of the tadpole gradually gets broader, while the tail gets thinner and thinner, till it finally disappears altogether; but before that happens, its place has been taken by two hind legs, which first appear under the skin and then gradually push their way through.

The fore legs next appear, and so on through all the stages of development, till in a longer or shorter time, according to the amount of warmth, light and food it can obtain, the complete frog appears.

But woe betide the unfortunate tadpole which, first of the shoal, attains to the dignity of possessing limbs, for so ferocious are the later ones, and so jealous of their precocious little brother, that they almost always fall upon him, and not content with killing, never rest till every morsel of him is eaten.
