Then on a sudden the famous Tier de Barrage broke out—the deadly barrier of fire that crumbles a line of trenches as a child pokes in an ant hill: the fire that covers an advance and withers an enemy attack. Here was what I had been waiting for through twenty-one months of war. I had caught snatches of it at a dozen points along the line. I had eaten luncheon by a battery near Dixmude, but they were lazy, throwing a shell or two only for each course. But here, just before the sun came up, 200 feet from us, a battery of twelve 75s fired continuously for twenty minutes. Just over the hill another battery cleared its throat and spoke. In the fields beyond us other batteries played continuously. Some of the men put cotton in their ears.

We ran through a devastated wood. The green forest has been raked by high explosive into dead stumps, and looks like a New Hampshire hillside when the match trust has finished with it. The road is a thing of mounds and pits, blown up and dug out by a four months' rain of heavy shells. The little American cars are like rabbits. They dip into an obus hole, bounce up again and spin on. They turn round on their own tails. They push their pert little noses up a hill, where the road is lined with famous heavy makes, stalled and wrecked. They refuse to stay out of service.

We rode back through the partially destroyed city of Verdun, lying trapped and helpless in its hollow of hills. We drove through its streets, some of them a pile of stones and plaster, others almost untouched, with charming bits of water view and green lawns and immaculate white fronts. The city reminded me of the victim whom a professional hypnotist displays in a shop window, where he leaves him lying motionless in the trance for exhibition purposes.

Verdun lay seemingly dead inside the range of German fire. But once the guns are forced back the city will spring into life.

Then we returned to the ambulance headquarters and in an open tent shared the excellent rations which the field service provides for its workers. We were sitting with the French lieutenant and discussing the values of rhythm in prose when the boys shouted to us from the next field. An aeroplane was dipping over an anchored sausage-shaped observation balloon. The aeroplane had marked its victim, which could not escape, as a bird darts for a worm. The balloon opened up into flame and fell through thirty seconds, burning with a dull red.

The hours we had just spent of work and excitement seemed to me fairly crowded, but they were mild in the life of the field service. They pound away overtime and take ugly hazards and preserve a boy's humor. More young men of the same stuff are needed at once for this American Ambulance Field Service. The country is full of newly made college graduates, wondering what they can make of their lives. Here is the choicest service in fifty years offered to them.

Even a jitney wears out. Bump it in the carburetor enough times, rake it with shrapnel, and it begins to lose its first freshness. More full sections of cars should be given. The work is in charge of Piatt Andrew, who used to teach political economy in Harvard, was later Director of the Mint, Assistant Secretary of the Treasury and secretary of Senator Aldrich's Monetary Commission.

A. Piatt Andrew, who, as Director, has raised the American Ambulance Field Service from a small beginning to a powerful factor in rescue work.
