If You Have an Auger and No Nails
the craft may be fastened together with wooden pegs cut somewhat larger than the holes bored to receive them, and driven in with blows from your axe.
If you have long nails or spikes the problem is a simple one; but if you have neither auger, nails, nor spikes you must bind the joints with rope or hempen twine.
If you have neither nails, auger, nor rope, a good substitute for the latter can be made from the long,
Fibrous Inner Bark
of a dead or partly burned tree. For experiment I took some of the inner bark of a chestnut-tree which had been killed by fire and twisted it into a rope the size of a clothes-line, then I allowed two strong men to have a tug-of-war with it, and the improvised rope was stronger than the men.
How to Make a Fibre Rope
Take one end of a long, loose strand of fibres, give the other end to another person, and let both twine the ends between the fingers until the material is well twisted throughout its entire length; then bring the two ends together, and two sides of the loop thus made will twist themselves into a cord or rope half the length of the original strand.
If you nail or peg the parts, use your axe to flatten the joints by striking off a chip, as in Fig. 4.
If you must lash the joints together, cut them with log-cabin notches, as in Figs. 5 and 6.
If you have baggage to transport, make
A Dunnage Crib
by driving four stakes in cuts made near the end of the centre log and binding them with rope or fibre (Figs. 7 and 8), or by working green twigs basket-fashion around them, or make the rack saw-buck fashion, as shown by Fig. 7, and this will keep your things above water.
A couple of cleats nailed on each side of the log will be of great assistance and lessen the danger and insecurity of the footing.
A skilfully made logomaran will enable you to cross any stream with a moderate current and any small lake in moderate weather. It is not an especially dry craft, but it won't sink or upset, and will take one but a short time to knock it together.
CHAPTER II
HOME-MADE BOATS
Birth of the "Man-Friday" Catamaran—The Crusoe Raft and Chump Rafts
Not so very many years ago I remember visiting, in company with my cousin Tom, a small lake at the headwaters of the Miami. High and precipitous cliffs surround the little body of water. So steep were the great weather-beaten rocks that it was only where the stream came tumbling down past an old mill that an accessible path then existed. Down that path Tom and I scrambled, for we knew that large bass lurked in the deep, black holes among the rocks.
We had no jointed split-bamboo rods nor fancy tackle, but the fish there in those days were not particular and seldom hesitated to bite at an angle-worm or grasshopper though the hook upon which the bait squirmed was suspended by a coarse line from a freshly cut hickory sapling.
Even now I feel the thrill of excitement and expectancy as, in imagination, my pole is bent nearly double by the frantic struggles of those "gamy" black bass. After spending the morning fishing we built a fire upon a short stretch of sandy beach, and cleaning our fish and washing them in the spring close at hand, we put them among the embers to cook.
While the fire was getting our dinner ready for us we threw off our clothes and plunged into the cool waters of the lake. Inexpert swimmers as we were at that time, the opposite shore, though apparently only a stone's throw distant, was too far off for us to reach by swimming. Many a longing and curious glance we cast toward it, however, and strong was the temptation that beset us to try the unknown depths intervening. A pair of brown ears appeared above the ferns near the water's edge, and a fox peeped at us; squirrels ran about the fallen trunks of trees or scampered up the rocks as saucily as though they understood that we could not swim well enough to reach their side of the lake; and high up the face of the cliff was a dark spot which we almost knew to be the entrance to some mysterious cavern.

How we longed for a boat! But not even a raft nor a dugout could be seen anywhere upon the glassy surface of the water or along its rocky border. We nevertheless determined to explore the lake next day, even if we should have to paddle astride of a log.
The first rays of the morning sun had not reached the dark waters before my companion and I were hard at work, with axe and hatchet, chopping in twain a long log we had discovered near the mill. We had at first intended to build a raft; but gradually we evolved a sort of catamaran. The two pieces of log we sharpened at the ends for the bow; then we rolled the logs down upon the beach, and while I went into the thicket to chop down some saplings my companion borrowed an auger from the miller. We next placed the logs about three feet apart, and marking the points where we intended to put the cross-pieces, we cut notches there; then we placed the saplings across, fitting them into these notches. To hold them securely we bored holes down through the sapling cross-pieces into the logs; with the hatchet we hammered wooden pegs into these holes. For the seat we used the half of a section of log, the flat side fitting into places cut for that purpose. All that remained to be done now was to make a seat in the stern and a pair of rowlocks. At a proper distance from the oarsman's seat we bored two holes for a couple of forked sticks, which answered admirably for rowlocks; across the stern we fastened another piece of log similar to that used for the oarsman's seat (Fig. 8½). With the help of a man from the mill our craft was launched; and with a pair of oars made of old pine boards we rowed off, leaving the miller waving his hat.
Our catamaran was not so light as a row-boat, but it floated, and we could propel it with the oars, and, best of all, it was our own invention and made with our own hands. We called it a "Man-Friday," and by its means we explored every nook in the length
