Wind and tide still favored them. In safety they passed the ugly shoals and ledges. Here Stern took the paddle, while Beatrice went to the bow and left all to his directing hand.
By three o'clock in the afternoon they were drawing past Blackwell's Island. The Queensboro Bridge still stood, as did the railway bridges behind them; but much wreckage had fallen into the river, and in one place formed an ugly whirlpool, which Stern had to avoid by some hard work with the paddle.
The whole structure was sagging badly to southward, as though the foundations had given way. Long, rusted masses of steel hung from the spans, which drooped as though to break at any moment. Though all the flooring had vanished centuries before, Stern judged an active man could still make his way across the bridge.
“That's their engineering,” gibed he, as the little boat sailed under and they looked up like dwarfs at the legs of a Colossus. “The old Roman bridges are good for practically eternity, but these jerry steel things, run up for profits, go to pieces in a mere thousand years! Well, the steel magnates are gone now, and their profits with them. But this junk remains as a lesson and a warning, Beta; the race to come must build better than this, and sounder, every way!”
On, on they sailed, marveling at the terrific destruction on either hand--the dense forests now grown over Brooklyn and New York alike.
“We'll be there before long now,” said Allan. “And if we have any luck at all, and nothing happens, we ought to be started for home by nightfall. You don't mind a moonlight sail up the Hudson, do you?”
It was past four by the time the banca nosed her way slowly in among the rotten docks and ruined hulks of steamships, and with a gentle rustling came to rest among the reeds and rushes now growing rank at the foot of what had once been Twenty-Third Street.
A huge sea-tortoise, disturbed, slid off the sand-bank where he had been sunning himself and paddled sulkily away. A blue heron flapped up from the thicket, and with a frog in its bill awkwardly took flight, its long neck crooked, legs dangling absurdly.
“Some mighty big changes, all right,” commented Stern. “Yes, there's got to be a deal of work done here before things are right again. But there's time enough, time enough--there's all the time we need, we and the people who shall come after us!”
They made the banca fast, noting that the tide was high and that the leather cord was securely tied to a gnarled willow that grew at the water's edge. Half an hour later they had made their way across town to Madison Avenue.
