demand of modern warfare is coal depots, and docks and machine-shops, established in ports easy of access, and protected by natural and artificial strength, and scattered at easy distances all over the commercial world. In short, men will appreciate better than they do now, that the right arm of naval warfare is not mail-clad steamers, but well-chosen colonies. * * * * * The sagacity of England was never more clearly shown than in the foresight with which she has provided against such an emergency. Let war come when it may, it will not find England in this respect unprepared. So thickly are her colonies scattered over the face of the earth, that her war-ships can go to every commercial centre on the globe without spreading so much as a foot of canvas to the breeze. There is the Mediterranean Sea. A great centre of commerce. It was a great centre as long ago as when the Phoenician traversed it, and, passing through the Straits of Hercules, sped on his way to distant and then savage Britain. It was a great centre when Rome and Carthage wrestled in a death-grapple for its possession. But England is as much at home in the Mediterranean as if it were one of her own lakes. At Gibraltar, at its entrance, she has a magnificent bay, more than five miles in diameter, deep, safe from storms, protected from man's assault by its more than adamantine rock. In the centre, at Malta, she has a harbor, land-locked, curiously indented, sleeping safely beneath the frowning guns of Valetta. But from Southampton to Gibraltar is for a steamship an easy six days' sail; from Gibraltar to Malta not more than five days; and from Malta to the extreme eastern coast of the sea and back again hardly ten days' sail. Take the grand highway of nations to India. England has her places of refreshment scattered all along it with almost as much regularity as depots on a railroad. From England to Gibraltar is six days' sail; thence to Sierra Leone twelve days; to Ascension six days; to St. Helena three days; to Cape Colony eight days; to Mauritius not more; to Ceylon about the same; and thence to Calcutta three or four days. Going farther east, a few days' sail will bring you to Singapore, and a few more to Hong Kong, and then you are at the gates of Canton. Mark now that in this immense girdle of some twelve or fifteen thousand miles there is no distance which a well-appointed steamer may not easily accomplish with such store of coal as she can carry. She may not, indeed, stop at all these ports. It may be more convenient and economical to use sails a part of the distance, rather than steam. But, if an exigency required it, she could stop and find everywhere a safe harbor.
