CHAPTER V.

PREPARING FOR THE EXPEDITION.

School closed on the 21st of June that year, just ten days before the

expected arrival of Uncle Ed. The first thing we did was to set up our

tent in the back yard and camp out so as to become acclimatized. It is

good that we did this, for the very first night a heavy summer shower

came up which nearly drenched us. The water beat right through the thin

canvas roof of our tent. Had we been able to afford the best quality of

canvas duck, such an occurrence would probably have been avoided. But we

solved the difficulty by using a tent fly; that is, a strip of canvas

stretched over the tent and spaced a short distance from it to break the

fall of the rain drops.

TENT FLY.

Again we had to visit the village storekeeper; this time we bought out

his whole remaining stock, sixteen yards of drill. This was cut into

four-yard strips, which were sewed together as before and the ends

turned up and hemmed. Tie strings were sewed to the ends of the strips

so that the fly could be tied to the wall ropes of the tent. At the

ridge the fly was supported about six inches above the tent rope by a

second ridge pole held by pegs in the top holes of the tent posts.

PROVISIONS AND SUPPLIES.

The ten days before Uncle Ed arrived were busy indeed. We had to gather

together the necessary provisions and supplies. Our personal outfits

were very simple. Each member supplied himself with a change of

underwear, a bathing suit, a blanket and a toothbrush. A single comb and

brush served for the entire society, and was used on Sundays, the only

day we really dressed up. All the rest of the time we lived in our

bathing suits, except, of course, on cold rainy days. Our kitchen outfit

consisted of a large cooking pot, two kettles, a frying pan, a coffee

pot, a small oil stove, a half-dozen each of plates, cups, saucers,

knives and forks, a dozen spoons, two tablespoons, and, in addition,

several large plates and bowls for pantry use. We also took with us a

dish-pan and several dish-towels. For our larder we collected the

following: A bag of flour, ten pounds of sugar, two pounds of salt,

three pounds of coffee, four pounds of oatmeal, four pounds of butter,

two pounds of lard, six pound of beans, six pounds of rice, three pounds

of bacon, six cans of condensed milk, a dozen eggs, box of pepper, and

several jars of canned peaches and pears, and also a half dozen glasses

of jelly.

It was Dutchy who suggested that we have a chicken yard, in connection

with our camp, to supply us with fresh eggs. It was a capital idea, and

by the dint of some coaxing we managed to secure the loan of a half

dozen hens and a rooster.

Our miscellaneous list included a spade, pick and shovel, an ax, a

hatchet, two large pails, a barn lantern, a can of kerosene, a dozen

candles, a cocoa box filled with matches, a pair of scissors, needles,

buttons, pins and safety pins, a spool of white and another of black

cotton, fishing tackle, a roll of heavy twine, a coil of rope, and a set

of dominoes and checkers. But most important of all was a chest of tools

belonging to Reddy. These were all collected when Uncle Ed arrived.

Dutchy also contributed a large compass, which we found very useful

later on, for surveying the island.

CROSSBOW.

Reddy had a shotgun which he wanted to bring along, but my father, and

Dutchy's as well, wouldn't let us go camping if there was to be any

gunpowder along, so we had to leave it behind. Of course we didn't miss

it at all when we got to the island, because there was so much else to

do; but we all agreed with Dutchy, that "it wouldn't be no sort of a

scientific expedition without takin' a gun along." As a substitute I

suggested a bow and arrow. They all laughed at such a "kiddish" idea;

all but Bill, I mean.

[Illustration: Fig. 53. The Umbrella Rib Crossbow.]

"It ain't such a bad notion," said he, "only a crossbow would be better.

I've seen them made out of umbrella ribs so they'd shoot like greased

lightning." Of course we had to have one of these wonderful weapons.

Down in the ash heap we found two broken umbrellas with 27-inch ribs.

Bill selected ten good ribs, from which he wrenched off the spreaders

with a pair of pliers. The ribs were then bound together by winding

stout twine around them. The winding was very evenly and closely done,

so that the cord completely covered the ribs, making a solid rod of

spring steel. But before winding we had laid in between the ribs a piece

of heavy twine, to which the bowstrings could be tied after the bow was

all wound. The stock of our crossbow was cut out of a board of soft wood

1 inch thick to as near the shape of a gun as we could get it. A hole

was drilled through the muzzle end to receive the bow, and then the

bowstring was tied fast. Along the upper edge of the barrel a V-shaped

channel was cut. The channel was not very deep, only enough to receive a

tenpenny nail with the head projecting half-way above the sides. A notch

was cut across the barrel, through this channel, at the trigger end, and

a trigger made of heavy iron wire, bent to the shape shown in Fig. 51,

was hinged to the gun by a bolt which passed clear through the stock and

through both eyes of the trigger. By using two nuts on the bolt, and

tightening one against the other, they were prevented from working loose

and coming off. When we wanted to fire the gun the bowstring was drawn

back, and held by slipping it into the notch, and a nail was laid in the

channel with its head against the bowstring. Then, on pulling the

trigger, the bowstring was lifted out of the notch, and sent the nail

off sailing. The long-grooved barrel insured a very good aim.

MEGAPHONE.

[Illustration: Fig. 57. The Mouthpiece.]

Another device we made in preparation for the expedition was a

megaphone. A sheet of light cardboard 30 inches square was procured. At

the center of one edge a pin was stuck into the cardboard, then a piece

of stout thread was looped over the pin and the two ends were knotted

together just 5 inches from the pin. Another knot was also made 29

inches from the pin. Now, with a pencil hooked into the loop, and

resting first against the inner knot and then against the outer one, two

arcs were drawn on the paper, one of 5-inch radius and the other of

29-inch radius. A line was now drawn from the pin to the point where the

longer arc met the right hand edge of the paper, and a dotted line was

drawn from the pin to a point 1-1/2 inches from the edge at the other

end of the arc. From a point 1 inch to the left of the pin we then drew

a line to the left end of the arc. With a scissors we cut the cardboard

along the arcs and straight lines, all but the dotted line, leaving a

piece of the shape shown in Fig. 55. This piece was rolled into a cone

with the right edge lapped over the left edge and lying against the

dotted line. In this position it was held by means of several brass

fasteners of the kind shown in Fig. 56.

A mouthpiece was formed out of a block of wood in which a large hole had

been drilled. The block was then cut away until the walls were quite

thin. The hole was reamed out at the top, as shown in Fig. 57, and the

outer surface was tapered so that the small end of the megaphone would

fit snugly on it.

We planned to reach our camping grounds by way of the canal, and had

provided for that purpose a large scow, which we expected to tow up to

Lumberville and drag over to the river.

THE SCOW.

[Illustration: Fig. 62. Thole Pin.]

[Illustration: Fig. 63. Nailing on the Decks.]

[Illustration: Fig. 64. The Oar.]

Our scow was made as follows: Two 3/4-inch pine boards, 12 inches wide

and 12 feet long, were selected from Reddy's father's lumber pile. These

were used for the side pieces of the boat, and we tapered them off at

the end to a width of 3-1/2 inches. This was done by making a straight

cut from the end to a point three feet back along the edge of the board

and then rounding off the edge with a draw-knife. When one board had

been shaped, it was used as a pattern for the other, which was thus cut

to exactly the same size. For the end pieces two strips, 4 inches wide

and 2 feet 10-1/2 inches long, were sawed out of a 1-inch board. Then

for the bottom we procured a number of 3/4-inch boards, 12 feet long and

8 inches wide, which we cut into 3-foot lengths. At Bill's suggestion,

before nailing the parts together, we secured some strips of flannel,

which were saturated with paint, and laid between the seams so as to

make the boat perfectly water-tight. The side and end boards were then

nailed together, with the strips of flannel between, the side boards

overlapping the end boards, as shown in Fig. 59. After planing down the

end boards until their edges laid flush with the edges of the side

pieces, the bottom boards were nailed on, strips of cloth being inserted

between them, as well as along the edges of the side and end boards. To

brace the bottom a 3/4-inch board was placed at the center, inside the

boat, and bent down against the floor, to which it was nailed with wire

nails. The nails were driven into the board from the outer side of the

boat and were clinched inside. Along the upper edges of the side boards

two strips 2 inches wide and 1 inch thick were nailed. Two notches were

cut in the inner side of each strip before it was nailed on. The notches

were 1/2 inch deep, 1-1/2 inches wide, 3 inches apart and about 5-1/2

feet from the stern end. When the strips were nailed in place these

notches formed sockets to receive the rowlocks. A strip was also nailed

across the stern of the boat and formed with two central notches, to

receive the rowlocks for a steering oar. This strip, however, was 3

inches wide, and projected 1 inch above the end board, so as to lie

flush with the deck boards, which were later applied. Six thole pins,

1/2 inch thick, 4-1/2 inches long and 2 inches wide, were cut out of an

oak board. The lower end of each pin was reduced to a width of 1-1/2

inches for a length of 2 inches. The thole pins were then fitted snugly

in the notches. Two cleats, nailed to the side boards inside, 7 inches

below the upper edge, served to support a seat board 1 inch thick and 2

feet 10-1/2 inches long. The aft edge of the seat was about 10 inches

forward of the rowlocks. The boat was completed by nailing on a couple

of deck boards at each end. The oars were made of 2-inch pine boards, 5

feet long and 5 inches wide. They were blocked out at Mr. Schreiner's

sawmill and then shaped and smoothed down with a draw-knife and

spoke-shaved. They were 1-1/4 inches at the handle and 2 inches

immediately below, tapering down to a diameter of 1-1/4 inches at the

top of the blade. The blades were 18 inches long, 5 inches wide, and

planed down to a thickness of 1/4 inch along the edges.
