The Mapmaker's Road Under the Water
A chart-maker sounds a drowned road between the islands for the Admiralty, and each sounding he takes brings a little more of the road up through his lead line.
The Admiralty pays Osric Thale to make the chart of the Cala Mare shoals, and for two summers he has done it the way the old men taught him, with a lead line, a notebook and a skiff that smells of tar. The shoals are a cluster of rock and sand between three islands. The chart he has drawn so far is good. It is accurate to the fathom and it is ugly, with a crowd of soundings dotted across it like flies on a window.
In the third summer the soundings begin to line up.
He notices it first on the eastern run. He has been sounding a patch of sand for a week, dropping the lead, reading the mark where the line goes taut, writing the depth into the book. Four fathoms. Three and a half. Four. Then a sounding of nine feet where there should be none, a little hump of rock that the existing chart does not show. He marks it. The next sounding, a hundred yards farther on, is nine feet again. Then a third, at exactly the same depth, on a line running straight north.
Osric thinks it is a shelf. He takes the skiff further along the line and sounds every twenty yards. Nine feet, nine feet, nine feet, and then, where the line crosses a bay he has previously marked as open water, something that the lead cannot quite reach. He pays out the whole coil and it touches nothing. He hauls it back in and finds the bottom of the lead painted with a thin, pale grey, like the dust off old stone.
He goes back to the chart-house that evening and lays his soundings over the older survey. The older survey shows the bay empty. But when he traces his new line across it, and joins the nine-foot soundings with a pencil, the line runs straight through the middle of the bay and out again on the far side and makes, very clearly, the course of a road.
It is not a natural line. Roads are made. He knows this from the Admiralty's own maps, which show the old causeways of the mainland, but he has never seen one this straight, under this much water.
The chart-house clerk, a dry young man named Pell, looks over his shoulder and says the sea has no roads. Osric says he knows. He says he is only telling the chart what the lead says. Pell says the Admiralty will want a second survey before they print anything that looks like a road, and Osric agrees, and goes out again the next morning.
The road comes up through the lead a little more each day. By the end of the month he can follow it for nearly two miles between the islands, a long low ridge of nine-foot water with a pale grey dust on the bottom, and he has begun to see things in the sounding book that he did not write down. Small marks beside the soundings. Little crosses, in a hand that is not his, that show up where he has been, each one a yard from the last. Once, at the end of a long run, he finds a single word scratched into the notebook margin in a careful copperplate: *Mind.*
He does not remember writing anything of the kind. He does not remember the notebook leaving his coat. He closes it and sounds another two hundred yards, and by the time he gets back to the skiff his hands are shaking.
The fishermen of the outer island, when he asks them, say there was a village on the far side of the bay before the sea came up, and a road that went out to it on causeway stones, and a church with a bell that could be heard on the mainland on still days. They say the village went under in a storm that lasted nine days, and that the road is still there, and that you can walk on it at low spring tides if you know the way. They say nobody walks it now. They say the bell still rings sometimes, under the water, at the hour the storm began.
Osric does not walk it. He finishes the survey in the autumn, every sounding taken to the fathom, and he prints the chart with the bay marked as shallow, nine feet, a clear ridge running through it. The Admiralty objects to the ridge and asks for it to be removed. He puts it back in. He is paid in full, and the chart is issued the following year, and it is accurate. It is the only chart on the coast that shows the road, and every skipper who uses it, the old men say, takes the course along the ridge without ever quite knowing why he keeps to it.
