"Where have they come from do you think, Master Lirriper?"
"Well, they may have come out from Burnham, or they may have come down from London and be going up to Burnham or to Bricklesey when the tide turns. There is a large ship anchored in the channel beyond the Whittaker. Of course she is going up when tide begins to flow. And there are the masts of two vessels right over there. They are in another channel. Between us and them there is a line of sands that you will see will show above the water when it gets a bit lower. That is the main channel, that is; and vessels coming from the south with a large draught of water generally use that, while this is the one that is handiest for ships from the north. Small vessels from the south come in by a channel a good bit beyond those ships. That is the narrowest of the three; and even light draught vessels don't use it much unless the wind is favourable, for there is not much room for them to beat up if the wind is against them."
"What is to beat up, Master Lirriper?"
"Well, you will see about that presently. I don't think we shall be able to lay our course beyond the Whittaker. To lay our course means to steer the way we want to go; and if we can't do that we shall have to beat, and that is tedious work with a light wind like this."
They dropped anchor off the beacon, and the captain said that this was the time to take breakfast. The lads already smelt an agreeable odour arising from the cabin forward, where the boy had been for some time busily engaged, and soon the whole party were seated on the lockers in the cabin devouring fried fish.
"Master Chambers," Geoffrey said, "we have got two boiled pullets in our basket. Had we not better have them for dinner? They were cooked the evening before we came away, and I should think they had better be eaten now."
"You had better keep them for yourselves, Master Geoffrey," the skipper said. "We are accustomed to living on fish, but like enough you would get tired of it before we got to London."
But this the boys would not hear of, and it was accordingly arranged that the dinner should be furnished from the contents of the basket.
As soon as tide turned the anchor was hove up and the Susan got under way again. The boys soon learnt the meaning of the word beating, and found that it meant sailing backwards and forwards across the channel, with the wind sometimes on one side of the boat and sometimes on the other. Geoffrey wanted very much to learn why, when the wind was so nearly ahead, the boat advanced instead of drifting backwards or sideways. But this was altogether beyond the power of either Master Lirriper or Joe Chambers to explain. They said every one knew that when the sails were full a vessel went in the direction in which her head pointed. "It's just the same way with yourself, Master Geoffrey. You see, when you look one way that's the way you go. When you turn your head and point another way, of course you go off that way; and it's just the same thing with the ship."
"I don't think it's the same thing, Master Lirriper," Geoffrey said puzzled. "In one case the power that makes one go comes from the inside, and so one can go in any direction one likes; in the other it comes from outside, and you would think the ship would have to go any way the wind pushes her. If you stand up and I give you a push, I push you straight away from me. You don't go sideways or come forward in the direction of my shoulder, which is what the ship does."
John Lirriper took off his cap and scratched his head.
"I suppose it is as you say, Master Geoffrey, though I never thought of it before. There is some reason, no doubt, why the craft moves up against the wind so long as the sails are full, instead of drifting away to leeward; though I never heard tell of it, and never heard anyone ask before. I daresay a learned man could tell why it is; and if you ask your good father when you go back I would wager he can explain it. It always seems to me as if a boat have got some sort of sense, just like a human being or a horse, and when she knows which way you wants her to go she goes. That's how it seems to me—ain't it, Joe?"
"Something like that, uncle. Every one knows that a boat's got her humours, and sometimes she sails better than she does others; and each boat's got her own fancies. Some does their best when they are beating, and some are lively in a heavy sea, and seem as if they enjoy it; and others get sulky, and don't seem to take the trouble to lift their bows up when a wave meets them; and they groans and complains if the wind is too hard for them, just like a human being. When you goes to a new vessel you have got to learn her tricks and her ways and what she will do, and what she won't do, and just to humour her as you would a child, I don't say as I think she is actually alive; but every sailor will tell you that there is something about her that her builders never put there."
"That's so," John Lirriper agreed. "Look at a boat that is hove up when her work's done and going to be broken up. Why, anyone can tell her with half an eye. She looks that forlorn and melancholy that one's inclined to blubber at the sight of her. She don't look like that at any other time. When she is hove up she is going to die, and she knows it."
"But perhaps that's because the paint's off her sides and the ropes all worn and loose," Geoffrey suggested.
But Master Lirriper waved the suggestion aside as unworthy even of an answer, and repeated, "She knows it. Anyone can see that with half an eye."
Geoffrey and Lionel talked the matter over when they were sitting together on deck apart from the others. It was an age when there were still many superstitions current in the land. Even the upper classes believed in witches and warlocks, in charms and spells, in lucky and unlucky days, in the arts of magic, in the power of the evil eye; and although to the boys it seemed absurd that a vessel should have life, they were not prepared altogether to discredit an idea that was evidently thoroughly believed by those who had been on board ships all their lives. After talking it over for some time they determined to submit the question to their father on their return.
It took them two more tides before they were off Sheerness. The wind was now more favourable, and having increased somewhat in strength, the Susan made her way briskly along, heeling over till the water ran along her scuppers. There was plenty to see now, for there were many fishing-boats at work, some belonging, as Master Chambers told them, to the Medway, others to the little village of Leigh, whose church they saw at the top of the hill to their right. They met, too, several large craft coming down the river, and passed more than one, for the Susan was a fast boat.
"They would beat us," the skipper said when the boys expressed their surprise at their passing such large vessels, "if the wind were stronger or the water rough. We are doing our best, and if the wind rises I shall have to take in sail; while they could carry all theirs if it blew twice as hard. Then in a sea, weight and power tell; a wave that would knock the way almost out of us would hardly affect them at all."
So well did the Susan go along, that before the tide was much more than half done they passed the little village of Gravesend on their left, with the strong fort of Tilbury on the opposite shore, with its guns pointing on the river, and ready to give a good account of any Spaniard who should venture to sail up the Thames. Then at the end of the next reach the hamlet of Grays was passed on the right; a mile further Greenhithe on the left. Tide was getting slack now, but the Susan managed to get as far as Purfleet, and then dropped her anchor.
"This is our last stopping-place," Joe Chambers said. "The morning tide will carry us up to London Bridge."
"Then you will not go on with to-night's tide?" Geoffrey asked.
"No; the river gets narrower every mile, and I do not care to take the risk of navigating it after dark, especially as there is always a great deal of shipping moored above Greenwich. Tide will begin to run up at about five o'clock, and by ten we ought to be safely moored alongside near London Bridge. So we should not gain a great deal by going on this evening instead of to-morrow morning, and I don't suppose you are
