At first the headguard opposed the suggestion. The driver was under his orders, and he would not give his consent to the engine being touched. Then, giving way to argument, he said:

"If you take the responsibility, all right!"

Only it was a hard job. Stretched out beneath the engine, with their backs in the melting snow, Jacques and Pecqueux had to toil for nearly half an hour. Fortunately they had spare screwdrivers in the toolchest. At last, at the risk of burning themselves and getting crushed a score of times over, they managed to take the ash-pan down. But they had not done with it yet. It was necessary to drag it away. Being an enormous weight, it got jammed in the wheels and cylinders. Nevertheless, the four together were able to pull it out, and drag it off the line to the foot of the embankment.

"Now let us finish clearing away the snow," said the guard.

The train had been close upon an hour in distress, and the alarm of the passengers had increased. Every minute a glass went down, and a voice inquired why they did not go on. There was a regular panic, with shouts and tears, in an increscent crisis of craziness.

"No, no, enough has been cleared away," said Jacques. "Jump up, I'll see to the rest."

He was once more at his post, along with Pecqueux, and when the two guards had gained their vans, he turned on the exhaust-tap. The deafening rush of scalding steam melted the remainder of the snow still clinging to the line. Then, with his hand on the wheel, he reversed the engine, and slowly retreated to a distance of about four hundred yards, to give it a run. And having piled up the fire, and attained a pressure exceeding what was permitted by the regulations, he sent La Lison against the wall of snow with all its might and all the weight of the train it drew.

The locomotive gave a terrific grunt, similar to that of a woodman driving his axe into a great tree, and it seemed as though all the powerful ironwork was about to crack. It could not pass yet. It came to a standstill, smoking and vibrating all over with the shock. Twice the driver had to repeat the manœuvre, running back, then dashing against the snow to drive it away. On each occasion, La Lison, girded for the encounter, struck its chest against the impediment with the furious respiration of a giant, but to no purpose. At last, regaining breath, it strained its metal muscles in a supreme effort and passed, while the train followed ponderously behind, between the two walls of snow ripped asunder. It was free!

"A good brute, all the same!" growled Pecqueux.

Jacques, half blinded, removed his spectacles and wiped them. His heart beat hard. He no longer felt the cold. But abruptly he remembered a deep cutting, some four hundred yards away from La Croix-de-Maufras. It opened in the direction of the wind, and the snow must have accumulated there in a considerable quantity. He at once felt certain that this was the rock, marked out, whereon he would founder. He bent forward. In the distance, after a final curve, the trench appeared before him in a straight line, like a long ditch full of snow. It was broad daylight, and the boundless whiteness sparkled amid the unceasing fall of snowflakes.
