This board also had power to commandeer ships, when they had to—notably in the case of bringing shipments of coal from England, where it was fairly plentiful, to France, where there was almost none.

A second scheme for co-ordination put into effect by General Pershing was a board at which heads of all army departments could meet and act direct, without the necessity of going through the commander-in-chief. When the quartermaster's department made its budgets, the co-ordination department went over them and revised the estimates downward, or drafted work or supplies from some other department with a surplus, or redistributed within the quartermaster's stores, perhaps even granted the first requests. But there was a vast saving throughout the army zone.

The problem of America's "behind the lines," including as it did the creating of every phase of transportation, from trackage to terminals, and then providing the things to transport, not only for an army growing into the millions, but for much of civilian France, was one which, all wise observers said, was the greatest of the war. Just how staggering were these difficulties must not be told till later, but surmises are free. And the praise for overcoming them which poured from British and French onlookers had the value and authority of coming from men who had themselves been through like crises, and who knew every obstacle in the way of the Americans.

But if the preparatory stages must be abridged in the telling, there is no ban on a little expansiveness as to what was finally done.

Within a year American engineers and laborers and civilians working behind the lines had made of the waste lands around an old French port a line of modern docks where sixteen heavy cargo-vessels could rest at the same time, being unloaded from both sides at once at high speed, by the help of lighters. These docks were made by a big American pile-driver, which in less than a year had driven 30,000 piles into the marshy ooze, and made a foundation for enormous docks.

Just behind the docks is a plexus of railway-lines which, what with incoming and outgoing tracks and switches and side-lines, contains 200 miles of trackage in the terminal alone.

It is for the present no German's business how many hundred miles of double and triple track lead back to the fighting-line, and it is the censor's rule that one must tell nothing a German shouldn't know. But there is plenty of track, figures or no figures.

Equal preparation has been made for such supplies as must remain temporarily at the docks.

There are 150 warehouses, most of them completed, each 400 by 50 feet, and each with steel walls and top and concrete floors. When the warehouses are finished they will be able to hold supplies for an army of a million men for thirty days. They are supplemented by a giant refrigerating-plant, with an enormous capacity, which is served by an ice-making factory with an output of 500 tons daily, the whole ice department being operated by a special "ice unit" of the army, officially called Ice Plant Company 301. The ice department also has its own refrigerator-cars for delivering its wares frozen to any part of France.

To provide for gun appetites as abundantly as for human, an arsenal was begun at the same point, which, when completed, will have cost a hundred million dollars. This arsenal and ordnance-depot is being built by an American firm, at the request of the French Mission in America, who vetoed the American project to give the work to French contractors, because of the man-shortage in France.
