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.
