Except when there was a formal and actual state of war, the Moslem and Christian islands remained in a state of neutrality, trading with each other and avoiding all unfriendly proceedings that would lead to struggles which would be fatal to the prosperity of both. The Archipelago, and indeed the whole of the eastern portion of the Mediterranean, was infested by pirates, fitted out, for the most part, on the mainland. These, when in force, openly kept the sea, attacking the Christian merchant ships, but when cruising alone they hid in unfrequented bays, or behind uninhabited islets, until they could pounce upon a passing ship whose size promised an easy capture. The Order of St. John furnished a maritime police, earning thereby the deep gratitude of Spain, France, and Italy. They were aided occasionally by the Venetians, but these, being frequently engaged in quarrels with their neighbours, did but a small share of this work, only sending their fleets to sea when danger threatened some of their possessions in the Levant. “This is delightful, Ralph,” Gervaise said, as they stood together on the poop, looking back at the receding city. “What a pleasant change it is from standing in the broiling sun watching those poor wretches toiling at the fortifications! There is only one drawback to my pleasure. I wish that we carried sails, and were moved along by the breeze, instead of by the exertions of the slaves.” “Much chance we should have of catching a pirate under such circumstances!” Ralph said, laughing. “You might as well set a tortoise to catch a hare.” “I don't say that we should not be obliged to carry rowers, Ralph; but all the prizes that have been brought in since I have been at Rhodes carry masts and sails, as well as oars, and, as I understand, for the most part cruise about under sail, and only use the oars when chasing or fleeing.” “That is so; because, you see, in most cases the crew themselves have to row, and I have no doubt if we had no slaves to do the work we should soon take to masts and sails also; but for speed the rowing galleys are the best, for unless a brisk wind were blowing, the mast and sails would but check her progress when the oars were out, and at any rate constrain her to travel only before the wind. I know your weakness about the slaves, Gervaise; but as we could neither build our fortifications nor row our galleys without them, I cannot go as far as you do in the matter, though I own that I am sometimes sorry for them. But you must remember that it is the fault of their people, and not of ours, that they are here.” “All that is true enough, Ralph, and I cannot gainsay you. Still I would rather that we were gliding along with sails instead of being rowed by slaves.”
