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,

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.
