as a man's thumb." Forecastle and poop were alike lofty, with a lower
waist for the use of sweeps if needful. But this was only exceptional,
sails being the usual motive power. And these were constructed chiefly
with a view to strength. Instead of canvas, they were formed of
untanned hides. And instead of hempen cables the Veneti were so far
ahead of their time as to use iron chains with their anchors; an
invention which perished with them, not to come in again till the 19th
century. Their broad beam and shallow keel enabled these ships to
lie more conveniently in the tidal inlets on either side of the
Channel.[70]

B. 2.--Thus equipped, the Veneti had tapped the tin trade at its
source, and established emporia at Falmouth, Plymouth, and Exmouth;
on the sites of which ancient ingots, Gallic coins of gold, and
other relics of their period have lately been discovered. Thence they
conveyed their freight to the Seine, the Loire, and even the Garonne.
The great Damnonian clan, which held the whole of Devon and Cornwall,
were in close alliance with them, and sent auxiliaries to aid in their
final struggle against Caesar. Indeed they may possibly have drawn
allies from a yet wider area, if, as Mr. Elton conjectures, the
prehistoric boats which have at various times been found in the silt
at Glasgow may be connected with their influence.[71]

B. 3.--Caesar describes his struggle with the Veneti and their British
allies as one of the most arduous in his Gallic campaigns. The Roman
war galleys depended largely upon ramming in their sea-fights, but the
Venetian ships were so solidly built as to defy this method of attack.
At the same time their lofty prows and sterns enabled them to deliver
a plunging fire of missiles on the Roman decks, and even to command
the wooden turrets which Caesar had added to his bulwarks. They
