From across the river came an almost continuous whistling of locomotives, backed by the rumble of stone. Hitchcock at the last minute was spending a few hundred more trucks of Tarakee stone in reinforcing his spurs and embankments.
“The bridge challenges Mother Gunga,” said Peroo, with a laugh. “But when she talks I know whose voice will be the loudest.”
For hours the naked men worked, screaming and shouting under the lights. It was a hot, moonless night; the end of it was darkened by clouds and a sudden squall that made Findlayson very grave.
“She moves!” said Peroo, just before the dawn. “Mother Gunga is awake! Hear!” He dipped his hand over the side of a boat and the current mumbled on it. A little wave hit the side of a pier with a crisp slap.
“Six hours before her time,” said Findlayson, mopping his forehead savagely. “Now we can’t depend on anything. We’d better clear all hands out of the river-bed.”
Again the big gong beat, and a second time there was the rushing of naked feet on earth and ringing iron; the clatter of tools ceased. In the silence, men heard the dry yawn of water crawling over thirsty sand.
Foreman after foreman shouted to Findlayson, who had posted himself by the guard-tower, that his section of the river-bed had been cleaned out, and when the last voice dropped Findlayson hurried over the bridge till the iron plating of the permanent way gave place to the temporary plank-walk over the three centre piers, and there he met Hitchcock.
“All clear your side?” said Findlayson. The whisper rang in the box of latticework.
“Yes, and the east channel’s filling now. We’re utterly out of our reckoning. When is this thing down on us?”
“There’s no saying. She’s filling as fast as she can. Look!” Findlayson pointed to the planks below his feet, where the sand, burned and defiled by months of work, was beginning to whisper and fizz.
