wood, and of many other islands in the Pacific, which are truly canoes and propelled by paddles, and the same peculiarity of build extends to the Madras surf boats, which are more truly boats. Many of these are tied together through holes drilled or burnt through a ledge left on the inner side of the plank or log, a peculiarity noticeable as appearing even in the early vessels of the Northern Seas. The stitched boat has not a nail or a peg in her whole composition, but the structure, though liable to leak, is admirably suited for heavy seas and surf-beaten coasts, and owing to its pliability will stand shocks which would shatter a stiffer and tighter build. This being so, it is not surprising that vessels larger than canoes or boats were constructed (some authorities say even as large as 200 tons burden) upon this principle, which is certainly one of very great antiquity.
There is also a curious analogy in the progress of construction of these sea-going craft with the natural order in the construction of fishes, that is to say, if the ganoids are to be considered antecedent to the vertebrates among the latter. For in the.case of the stitched vessels the hull is the first thing in time and construction, the ribs and framework being, so to speak, an afterthought, and attached to the interior when the hull has been completed, whereas the later and modern practice is to set up the ribs and framework of the vessel first and to attach the exterior planking afterwards. But the invention of trenails and dowels must have preceded the later practice, and have led the way to the building of such boats as those described by Herodotus (ii. 96), the ancestors of the Nile ‘nuggur’ of modern times. Ulysses, as a shipwright well skilled in his craft, uses axe and adze and auger, and with the latter makes holes in the timbers he has squared and planed, and with trenails and dowels ties them together. The wooden fastenings, be it remarked, are in size and diameter severally adapted, the first to resist the horizontal, the second to resist the vertical strain to which the raft would be exposed upon the waves. All this, we may observe, points to a stage anterior to that in which the use of metal nails and ties in ship- and boat-building had been introduced. Trenails and
