'It is paper of native Indian manufacture,' he remarked. 'It has at some time been pinned to a board. The diagram upon it appears to be a plan of part of a large building with numerous halls, corridors, and passages. At one point is a small cross done in red ink, and above it is "3.37 from left," in faded pencil-writing. In the lefthand corner is a curious hieroglyphic like four crosses in a line with their arms touching. Beside it is written, in very rough and coarse characters, "The sign of the four—Jonathan Small, Mahomet Singh, Abdullah Khan, Dost Akbar." No, I confess that I do not see how this bears upon the matter. Yet it is evidently a document of importance. It has been kept carefully in a pocket-book; for the one side is as clean as the other.'
