Not so very long after, I came to a place where another stream ran out of the wood into the one I had been following, and just below the place where the two joined there was--not a bridge, but a pole across, and another pole to serve as a rail, by which you could cross, without trouble. I did cross, not thinking much about it, but with some idea of looking at this new little stream, which went at a very quick pace and seemed to promise small rapids and waterfalls a little higher up. Now when I got to the edge of it, there was no mistake: it was saying "_Trickle-up_," or even "_Track-up_," much plainer than the old one. I stepped across it and went a few yards up the old stream. Before the new one joined it, it was saying nothing of the kind. I went back to the new one: it was talking as plain as print. Of course there were no two words about what must be done now. Here was something quite new, and even if I missed my tea, it had got to be looked into. So I went up the new stream into the wood. Though I was well on the look-out for unusual things--in particular the plant, which I could not help thinking about--I cannot say there was anything peculiar about the stream or the plants or the insects or the trees (except the words which the water kept saying) so long as I was in the flat part of the wood. But soon I came to a steepish bank--the land began to slope up suddenly and the rapids and waterfalls of the brook were very gay and interesting. Then, besides _Track-up_, which was now its word always instead of _Trickle_, I heard every now and then _All right_, which was encouraging and exciting. Still, there was nothing out of the way to be seen, look as I might. The climb up the slope or bank was fairly long. At the top was a kind of terrace, pretty level and with large old trees growing upon it, mainly oaks. Behind there was a further slope up and still more woodland: but that does not matter now. For the present I was at the end of my wanderings. There was no more stream, and I had found what of all natural things I think pleases me best, a real spring of water quite untouched.
