THREE:As Frank expressed it, "something was up," but what that something was they did not see any prospect of ascertaining immediately. After a few moments devoted to wondering what could be the meaning of the movements of the mysterious stranger, they dropped the subject and resumed their conversation about Japan.Frank had his eye on a sampan that was darting about like an active fish, first in one direction and then in another. It was propelled by a single oar in the hands of a brown-skinned boatman, who was not encumbered with a large amount of superfluous clothing. The oar was in two piecesa blade and a handlelashed together in such a way that they did not form a straight line. At first Frank thought there was something wrong about it; but he soon observed that the oars in all the boats were of the same pattern, and made in the same way. They were worked like sculls rather than like oars. The man kept the oar constantly beneath the water; and, as he moved it forwards and back, he turned it partly around. A rope near his hand regulated the distance the oar could be turned, and also kept it from rising out of the water or going too far below the surface.
