The principal of these manoeuvres were the work of the man whom they called the Colonel. He had formed the plan, with another man, of secretly watching the operation of heaving the log every time it was performed, and making a note of the result. By doing this, he thought he could calculate very nearly how many miles the ship would make, while all the other passengers would have nothing to guide them but such general estimates as they could make from recollection. He accordingly arranged it with his confederates that one or the other of them should be on deck whenever the men were called to heave the log, and, without appearing to pay any particular attention to the operation, carefully to obtain the result, and make a memorandum of it. This plan was sufficient for the daytime. For the night--inasmuch as it might excite suspicion for them to be up at unseasonable hours to watch the operation--they resorted to another method. They bribed one of the seamen of each watch to find out the result of each trial during his watch, and to give them the answers in the morning. When the last time for heaving the log, previous to making up the accounts for the day, came, which was at ten o'clock, they took that result, and then, shutting themselves up in their state room, they made a calculation, and ascertained pretty certainly, as they thought, that the distance would be about 267 miles. It might possibly be 266, or 268; but they thought that they were sure that it would be one of those three numbers. The next thing was to circulate statements, and to express opinions in private conversation here and there among the passengers, in a careless sort of way, to produce a general impression that the rate of the ship would be not less than 270 miles. This was to lead the owners of the tickets, and the betters generally, not to attach a high value to the numbers below 270. By doing this, they expected to depress the value of these tickets in the general estimation, so that they could buy then easily. They calculated that, if their plans succeeded, they could buy 266, 267, and 268 for about a sovereign apiece--the holders of them being made to suppose, by their manoeuvres that those numbers would have very little chance of obtaining the prize.
