When we had made a ridge of stones we laid turfs against them--nearly across the stream, leaving about two feet for the water to go through--then more stones, and then lumps of clay stamped down as hard as we could. The industrious beavers spent hours over it, with only one easy to eat cake in. And at last the dam rose to the level of the bank. Then the beavers collected a great heap of clay, and four of them lifted it and dumped it down in the opening where the water was running. It did splash a little, but a true-hearted beaver knows better than to mind a bit of a wetting, as Oswald told Alice at the time. Then with more clay the work was completed. We must have used tons of clay; there was quite a big long hole in the bank above the dam where we had taken it out.
When our beaver task was performed we went on, and Dicky was so hot he had to take his jacket off and shut up about icebergs.
I cannot tell you about all the windings of the stream; it went through fields and woods and meadows, and at last the banks got steeper and higher, and the trees overhead darkly arched their mysterious branches, and we felt like the princes in a fairy tale who go out to seek their fortunes.
And then we saw a thing that was well worth coming all that way for; the stream suddenly disappeared under a dark stone archway, and however much you stood in the water and stuck your head down between your knees you could not see any light at the other end.
The stream was much smaller than where we had been beavers.
Gentle reader, you will guess in a moment who it was that said--'Alice, you've got a candle. Let's explore.' This gallant proposal met but a cold response. The others said they didn't care much about it, and what about tea?
I often think the way people try to hide their cowardliness behind their teas is simply beastly.
Oswald took no notice. He just said, with that dignified manner, not at all like sulking, which he knows so well how to put on--'All right. I'M going. If you funk it you'd better cut along home and ask your nurses to put you to bed.' So then, of course, they agreed to go. Oswald went first with the candle. It was not comfortable; the architect of that dark subterranean passage had not imagined anyone would ever be brave enough to lead a band of beavers into its inky recesses, or he would have built it high enough to stand upright in. As it was, we were bent almost at a right angle, and this is very awkward if for long.
But the leader pressed dauntlessly on, and paid no attention to the groans of his faithful followers, nor to what they said about their backs.
It really was a very long tunnel, though, and even Oswald was not sorry to say, 'I see daylight.' The followers cheered as well as they could as they splashed after him. The floor was stone as well as the roof, so it was easy to walk on. I think the followers would have turned back if it had been sharp stones or gravel.
And now the spot of daylight at the end of the tunnel grew larger and larger, and presently the intrepid leader found himself blinking in the full sun, and the candle he carried looked simply silly. He emerged, and the others too, and they stretched their backs and the word 'krikey' fell from more than one lip. It had indeed been a cramping adventure. Bushes grew close to the mouth of the tunnel, so we could not see much landscape, and when we had stretched our backs we went on upstream and nobody said they'd had jolly well enough of it, though in more than one young heart this was thought.
It was jolly to be in the sunshine again. I never knew before how cold it was underground. The stream was getting smaller and smaller.
Dicky said, 'This can't be the way. I expect there was a turning to the North Pole inside the tunnel, only we missed it. It was cold enough there.'
But here a twist in the stream brought us out from the bushes, and Oswald said--'Here is strange, wild, tropical vegetation in the richest profusion. Such blossoms as these never opened in a frigid what's-its-name.'
It was indeed true. We had come out into a sort of marshy, swampy place like I think, a jungle is, that the stream ran through, and it was simply crammed with queer plants, and flowers we never saw before or since. And the stream was quite thin. It was torridly hot, and softish to walk on. There were rushes and reeds and small willows, and it was all tangled over with different sorts of grasses--and pools here and there. We saw no wild beasts, but there were more different kinds of wild flies and beetles than you could believe anybody could bear, and dragon-flies and gnats. The girls picked a lot of flowers. I know the names of some of them, but I will not tell you them because this is not meant to be instructing. So I will only name meadow-sweet, yarrow, loose-strife, lady's bed-straw and willow herb--both the larger and the lesser.
Everyone now wished to go home. It was much hotter there than in natural fields. It made you want to tear all your clothes off and play at savages, instead of keeping respectable in your boots.
But we had to bear the boots because it was so brambly.
It was Oswald who showed the others how flat it would be to go home the same way we came; and he pointed out the telegraph wires in the distance and said--'There must be a road there, let's make for it,' which was quite a simple and ordinary thing to say, and he does not ask for any credit for it. So we sloshed along, scratching our legs with the brambles, and the water squelched in our boots, and Alice's blue muslin frock was torn all over in those crisscross tears which are considered so hard to darn.
We did not follow the stream any more. It was only a trickle now, so we knew we had tracked it to its source. And we got hotter and hotter and hotter, and the dews of agony stood in beads on our brows and rolled down our noses and off our chins. And the flies buzzed, and the gnats stung, and Oswald bravely sought to keep up Dicky's courage, when he tripped on a snag and came down on a bramble bush, by saying--'You see it IS the source of the Nile we've discovered. What price North Poles now?'
