There was that hot June day down by the river—little stream it really was—that ran through a copse about half a mile from the school. It was on Farmer Dawson’s land, down in the hollow of the valley, up one side of which lay his big range of hop-gardens.
The Doctor paid him a certain rent for the right of the boys going down to this place, where a great dam had been built up of clay and clinkers. It was not all new, but done up afresh after lying a couple of hundred years or so untouched. All round it, Farmer Dawson used to send his men in the winter to cut down the coppice, trimming the ash and eating chestnut trees down to the stumps to make the young growth into hop-poles; but when the Doctor offered to take it and repair the dam, the hop-poles were left to grow and form a beautiful screen round this dell.
I remember what interest we boys took in it during one winter, when the Doctor had set a lot of men who were out of work to dig and wheel the clinkers and clay, a barrowful of one, and then a barrowful of the other, along the dam; and with old Lomax to give orders, we all marched and counter-marched in our thickest boots over the top of the dam, to trample it all down strong and firm.
You will think, perhaps, that it was easy enough to get clay, and so it was, for a thick bed lay only a few yards from the stream; but what about the clinkers?
I’ll tell you. There was quite a mine of them, hard, shiny fragments, some of which had run just like so much black or brown glass.
How did they get there, looking like so much volcanic slag? Why, they were the refuse from a huge iron furnace that used to be in full blast in the days of Queen Elizabeth or King James, and the dam we were repairing, after it had been grown over with trees, and the water reduced to a little stream, belonged to one of the old hammer ponds whose waters were banked up to keep a sufficiency to turn the big wheel that worked the tilt-hammers and perhaps blew the iron furnace till it roared.
For that peaceful rural part of Sussex was in those days a big forest, whose wood was cut down and made into charcoal. The forest is gone, and only represented now by patches of copsewood saved for cutting down every ten years or so for poles; but the iron lies there still in great veins or beds, though it is no longer dug out, the iron of to-day being found and smelted north and west, where coal-pits are handy; and the ironmasters of Sussex, whose culverins and big guns were famous all the world round, have given place to farmers and hop-growers, where grimy men used to tend the glowing metal and send it running into form and mould.
I have mentioned before how there used to be a furnace by Sir Hawkhurst’s penstock pond, where the embankment was still firm, but there had been a far more extensive one here, and the refuse went, as I have said, to repair the dam.
When this was done, the Doctor had a long low shed built and thatched and supplied with form-like seats, and a diving-board arranged, beside steps down in the shallow part for the younger boys, and the whole when finished made a glorious long pool of about an acre in extent, very deep by the dam, and sloping gradually up to a few inches only of water where the stream trickled in. And there, on the hot sunny afternoons, beautifully shut in by green waving trees, and with the water when we came to bathe so clear that you could see every stone on the gravelly bottom, we boys used to collect for a regular water frolic. But, as you may suppose, the water was not so clean when we had done, the paddling of the little fellows in the shallows discolouring it from end to end.
That special hot June afternoon cricket had been voted too tiring, and we had all gone down to the bathing-place, the non-swimmers having strict injunctions not to pass a couple of posts about half-way between the stream and the dam.
