as he was considered to be by the Moslems. The penalty for infraction of
this rule was death; otherwise, complete liberty of conscience was
accorded.

We have spoken of the two weapons held by the leaders of the Sea-wolves.
The first, as we have, said, was cupidity; the second was fanaticism, the
deadly religious hatred engendered, not only by the wholesale expropriation
of the Moslem population, but also by the persecution to which the
Moriscoes--as those Moslems were known who remained in Spain--were
subjected by their Christian masters. It requires little imagination to see
how these two weapons of avarice and intolerance could be made to serve the
purpose of those dominant spirits who rose to the summit of the piratical
hierarchy. Not only did they dazzle the imaginations of those who followed
in their train by promises of wealth uncounted, but they added to this the
specious argument that, in slaying and robbing the Christian wheresoever he
was to be found, the faithful Moslem was performing the service of God and
the act most grateful to his holy Prophet.

Could any rule of life be at the same time more simple and more attractive
to the beggared Mohammedan cast on the sterile shores of Northern Africa to

With the main stream of history, to which we have before referred, we have
no concern in this book. He who would embark thereon must sail a powerful
vessel which must carry many guns. Also for the conduct of this vessel many

separating the few precious grains of wheat from those mountains of chaff
