All along the starboard side of the ship in this part of her were stowed upwards of seven hundred boxes of tin-tacks, each box about twice the breadth and length of this book in your hand, and weighing pretty heavy. There was nothing else that I could think of that would so well answer the purpose of making a splash alongside, as one of these boxes, and which combined the same weight in so handy and portable a bulk. Anything in wood must float; anything in iron might be missed. All these things had to be carefully considered, for, easy as the job of dropping a weight overboard to counterfeit the sound of a human body fallen into the water may seem, yet in my case the difficulty of accomplishing it successfully, and without the chance of subsequent detection, was immense, and demanded great prudence and foresight. I conveyed one of these boxes to my cabin, and when four bells were struck (the hands kept the relief bells going for their own sakes, I giving them the time each day at noon), I smuggled it up in a topcoat, and stepped with an easy air on to the poop. The man who had been steering was in the act of surrendering the spokes to another hand, and I took advantage of one of them cutting off a piece of tobacco for the other, which kept them both occupied, to put my coat and the box inside it in the stern sheets of the port quarter-boat, as though it were my coat only which I had deposited there out of the road, handy to slip on should I require it. The boatswain observed my action without appearing to notice it; and as he passed me on the way to the cuddy, he said that his clothes would be ready by eight bells for the lady, and that I should find them in a bundle near the door. He would not stay to say more; for I believe that the carpenter had found something suspicious in our hanging together over the chart, and had spoken to this effect to his chums among the men; and it therefore behoved the boatswain and me to keep as clear of each other as possible. One stroke of fortune, however, I saw was to befall us. The night, unless a very sudden change took place, would be dark. The sky was thick, with an even and unbroken ground of cloud which had a pinkish tint down in the western horizon, where the sun was declining behind it. The sea was rough, and looked muddy. The wind held steady, but blew very fresh, and had drawn a trifle further to the southwards, so that the vessel was a point off her course. The motion of the ship was very uncomfortable, the pitching sharp and irregular, and she rolled as quickly as a vessel of one hundred tons would.
