"Babuji! Pigji! Dogji! What do these fat slugs from Calcutta know? He draws and draws and draws, and talks and talks and talks, and his maps are all wrong. I, Janki, know that this is so. When a man has been shut up in the dark for thirty years, God gives him knowledge. The old gallery that Tibu's gang made is not six feet from Number Five." "Without doubt God gives the blind knowledge," said Kundoo, with a look at Unda. "Let it be as you say. I, for my part, do not know where lies the gallery of Tibu's gang, but _I_ am not a withered monkey who needs oil to grease his joints with." Kundoo swung out of the hut laughing, and Unda giggled. Janki turned his sightless eyes toward his wife and swore. "I have land, and I have sold a great deal of lamp-oil," mused Janki; "but I was a fool to marry this child." A week later the Rains set in with a vengeance, and the gangs paddled about in coal-slush at the pit-banks. Then the big mine-pumps were made ready, and the Manager of the Colliery ploughed through the wet toward the Tarachunda River swelling between its soppy banks. "Lord send that this beastly beck doesn't misbehave," said the Manager, piously, and he went to take counsel with his Assistant about the pumps. But the Tarachunda misbehaved very much indeed. After a fall of three inches of rain in an hour it was obliged to do something. It topped its bank and joined the flood water that was hemmed between two low hills just where the embankment of the Colliery main line crossed. When a large part of a rain-fed river, and a few acres of flood-water, made a dead set for a nine-foot culvert, the culvert may spout its finest, but the water cannot _all_ get out. The Manager pranced upon one leg with excitement, and his language was improper. He had reason to swear, because he knew that one inch of water on land meant a pressure of one hundred tons to the acre; and here were about five feet of water forming, behind the railway embankment, over the shallower workings of Twenty-Two. You must understand that, in a coal-mine, the coal nearest the surface is worked first from the central shaft. That is to say, the miners may clear out the stuff to within ten, twenty, or thirty feet of the surface, and, when all is worked out, leave only a skin of earth upheld by some few pillars of coal. In a deep mine where they know that they have any amount of material at hand, men prefer to get all their mineral out at one shaft, rather than make a number of little holes to tap the comparatively unimportant surface-coal. And the Manager watched the flood.
