"Starboard it is." "D'ye know the compass?" "No." "Well, stop till we get down to Deal. Now, stand by me, and keep your eyes wide open; for, d'ye see, you've plenty to learn, and you can't begin too soon. We must square the mainyard, captain, if you please," continued he as we entered Blackwall Reach. "What could make the river so perverse as to take these two bends in Limehouse and Blackwall Reaches, unless to give pilots trouble, I can't say." The wind being now contrary from the sharp turn in the river, we were again tiding it down; that is, hove-to and allowing the tide to drift us through the Reach; but as soon as we were clear of Blackwall Reach, we could lay our course down the river. As we passed Gravesend, Bramble asked me whether I was ever so low down. "Yes," replied I, "I have been down as far as Sea Reach;" which I had been when I was upset in the wherry, and I told him the story. "Well, Tom, that's called the river now; but do you know that, many years ago, where we now are used to be considered as the mouth of the river, and that fort there" (pointing to Tilbury Fort) "was built to defend it? for they say the French fleet used to come and anchor down below." "Yes," replied I; "and they say, in the History of England, that the Danes used to come up much higher, even up to Greenwich; but that's a very long while ago." "Well, you beat me, Tom! I never heard that; and I think, if ever they did do so, they won't do it again in a hurry. What water have you got, my man? Port there!" "Port it is." "Steady--so." "Shall we get down to the Nore to-night, pilot?" said the captain. "Why, sir, I'm in hopes we shall; we have still nearly three hours' daylight; and now that we are clear of the Hope, we shall lay fairly down Sea Reach; and if the wind will only freshen a little (and it looks very like it), we shall be able to stem the _first_ of the flood, at all events." I ought to observe that Bramble, as soon as he had passed any shoal or danger, pointed it out to me; he said, "I tell it to you, because you can't be told too often. You won't recollect much that I tell you, I daresay; I don't expect it; but you may recollect a little, and every little helps." The tide had flowed more than an hour when we passed the Nore Light and came to an anchor. "What lights are those?" inquired I. "That's Sheerness," replied Bramble. "We were talking of the French and Danes coming up the river. Why, Tom, it is not much more than one hundred and fifty years ago when the Dutch fleet came up to Sheerness, destroyed the batteries, and landed troops there; howsomever, as I said of the French and the other chaps, they won't do so again in a hurry."
