Chapter III.

      The River.

      Mr. George and Rollo fell into the line of people that were pressing forward over the plank which led to the boat that the orange woman had directed them to embark in; and they soon found themselves on board. The boat was small and quite narrow. There was no saloon or enclosed apartment of any kind for the passengers, nor even an awning to shelter them from the sun or rain. There were, however, substantial settees placed around the deck, some forward and others aft. Some of these settees were on the sides of the steamer, by the railing, and there were others placed back to back in the middle. There were not seats enough for all the passengers; and thus many were obliged to stand.

      As the boat glided along swiftly over the water, Rollo gazed with wonder and interest at the various objects and scenes which presented themselves to view around him. The rows of dingy-looking warehouses dimly seen through the smoke along the shores of the river; the ranges of barges, lighters, and wherries lying at the margin of the water below; the bridges, stretching through the murky atmosphere across the stream, with throngs of people upon them passing incessantly to and fro; the little steamers, long and slender, and blackened by smoke, shooting swiftly in every direction over the surface of the water; and the spires and domes of the city seen on every hand beyond the nearer buildings,—attracted by turns the attention of our travellers, and excited their wonder.

      In a very few minutes, however, after the boat had left its first station, she seemed to be approaching another landing-place, and Rollo was very much amused to observe how the steamer was manœuvred in coming up to the landing and making fast there. The pilot who had the command of her stood upon the wheel house on one side, and gave his orders by means of little gestures which he made with his fingers and hand. The helmsman, who stood at the wheel in the stern, watched these gestures, and regulated his steering by such of them as were meant for him. There were other gestures, however, which were meant for the engineer, who had charge of the engine. This engineer, however, could not see the gestures of the pilot, for he was down among the machinery, beneath the deck; and so there was a boy stationed on the deck, near an opening which led down to where the engineer was standing; and this boy interpreted the gestures as the pilot made them, calling out to the engineer the import of them with a very curious drawling intonation, which amused Rollo very much. Thus, when the steamer approached the land, the boy, watching the fingers of the pilot, called out, with intervals of a few seconds between each order, in a loud voice to the engineer below, as follows:——

      “Ease—er-r-r!”

      Then, after two or three seconds,——

      “Stop—er-r-r!”

      Then again,——

      “Back—er-r-r!”

      The engineer obeyed all these orders in succession as they were thus announced to him; and the steamer was brought up very safely to the landing, although the person who controlled her motions could not see at all where he was going.

      When the steamer was thus, at length, moored to the landing, a number of the passengers stepped off, and a great many others got on; and, immediately afterwards, the cables were cast off, and the boy called out,——

      “Start—er-r-r!”

      The steamer then began to glide away from the landing again, and was soon swiftly shooting over the water towards one of the arches of the next bridge up the stream.

      “Now,” said Rollo, “how are they going to get this tall smokepipe through that bridge?”

      “You will see,” said Mr. George.

      Rollo looked up to the top of the smokepipe, which seemed to be considerably higher than the crown of the arch that the steamer was approaching. How it could possibly pass was a mystery. The mystery was, however, soon solved; for, at the instant that the bows of the steamer entered under the arch, two men, taking hold of levers below, turned the whole smokepipe back, by means of a hinge joint that had been made in it, not far from the deck. The hinge was in the back side of the smokepipe, and of course in bending the pipe back there was an opening made in front; and through this opening the smoke, while the steamer was passing through the bridge, came out in dense volumes. As soon, however, as the arch was cleared, the pipe was brought back into its place again by the force of great weights placed at the ends of the levers as a counterpoise. Thus the opening below was closed, and the smoke came out of the top of the pipe as before.
