It could be seen now of what elements it was made—­a throng of tiny specks, moving like stately birds, which, even as the eye watched, seemed to spread their wings upon the breeze that followed; to expand their bulk, and to glow, as the distance lessened, into the separate colours of each. . . .

Then once again bellowed the guns, heard now like the voice of articulate thunder five miles behind, rolling up the river as if to welcome this fleet upon its way; and still he kept his eyes upon those who came so swiftly.

There in front moved the great guard-ships, monsters of polished steel, decked at prow and stern with the huge banners that stood out straight behind in the swiftness of their coming, but which, even as he looked, flapped and bellied to this side and that as the speed decreased.  Then, wheeling outwards, disclosing as they wheeled the insignia that each bore, the eagles of Germany, the lilies of France and the rest, the guard of thirty giants fell once more into line, half a mile apart, as those that followed came on, and waited; beating the air with the shimmer of their netted wings.

Then ship after ship came up, each wheeling in its turn and waiting, building now up with the speed of thought a vast semicircle, expanding ever more and more swiftly, as the watcher looked—­himself halted now, with the royal barge on his right and his train of boats behind.  There each in its turn passed the air-navies of the Great Powers, come to bring their Lord with honour on his progress through the world—­vast armaments of inconceivable war, enrolled at last in the service of the Prince of Peace.

Then when the movement was complete, and there lay there across the burning blue of the sky, five hundred feet in air, this vast curve of glittering splendour, ten miles from horn to horn, on came the great fleet that they had escorted.

There, then, the watcher saw two by two, first the barges of the Papal Orders, the Order of the Holy Sepulchre with its five-fold cross, and the Golden Spur, leading—­huge medieval galleons, carved at prow and stem, each bearing its insignia; then came couple after couple bearing the Papal Court, followed closely by great barges, each with its canopy and throne, and the coat of the Cardinal whom each bore flying overhead.

And then a glorious sight.

For, moving alone in a solid phalanx, each vessel separated only by the space necessary for close manoeuvring, came the royal barges of Europe, ranked on either side by a line of guard-boats—­France, Austria, and Germany, then Belgium and Holland, then the Scandinavian kingdoms, then a crowd of lesser States from the Balkan, Greece, and the Black Sea; then the black-eagled barge of Russia, and finally the great galleons of Spain and Italy:  and on each sat a royal figure beneath a canopy of state.  And last of all moved a huge vessel, in scarlet and white, with a banner of white and gold and cross-keys at the prow; scarcely seen at first through the crowding craft, with a squadron of guard-ships coming after.
