"Why, in the mean time," said Mr. George, "the sailors in the boat have taken another anchor, and have gone forward with it to a new station; and so, when the ship has come up near enough to the first anchor, they shift the line and then proceed to warp to the second."
Rollo was much interested in these explanations; though, as most other boys would have been in his situation, he was a little disappointed to find himself mistaken in the opinion which he had advanced so confidently, that warping would be impracticable except in the immediate vicinity of the shore. Indeed, it often happens with boys, when they begin to reach what may be called the reasoning age, that, in the conversations which they hold with those older and better informed
than themselves, you can see very plainly that their curiosity and their appetite for knowledge are mingled in a very singular way with the pleasure of maintaining an argument with their interlocutor, and of conquering him in it. It was strikingly so with Rollo on this occasion.
"Yes," said he, after reflecting a moment on what his uncle had said, "yes; I see how they can warp by means of anchors, where there is a bottom which they can take hold of by them; but that is just the same as a shore. It makes no difference whether the line is fastened to an anchor on the bottom, or to a post or a tree on the land. One thing I am sure of, at any rate; and that is, that it would not be possible for them to warp a ship when it is out in the open sea."
"It would certainly seem at first view that they could not," replied Mr. George, quietly; "and yet they can."
"How do they do it?" asked Rollo, much surprised.
"It is not very often that they wish to do it," said Mr. George; "but they can do it, in this way: They have a sort of float, which is made in some respects on the principle of an umbrella. The sailors take one or two of these floats in a boat, with lines from the ship attached to them, and after rowing forward a considerable distance,
they throw them over into the water. The men at the capstan then, on board the ship, heave away, and the lines, in pulling upon the floats, pull them open, and cause them to take hold of the water in such a manner that the ship can be drawn up towards them. Of course the floats do not take hold of the water enough to make them entirely immovable. They are drawn in, in some degree, towards the ship; but the ship is drawn forward much more towards them."
"Yes," said Rollo; "I see that they might do it in that way. But I don't understand why they should have any occasion to warp a ship out in the open sea."
"They do not have occasion to do so often," replied Mr. George. "I have been told, however, that they resort to this method sometimes, in time of war, to get a ship away from an enemy in a calm. Perhaps, too, they might sometimes have occasion to do it in order to get away from an iceberg."
