At first there were about one hundred buildings on the 1,800 acres of unfenced land, about two hundred men being engaged in guarding the place. An organization of proved men had been made, which went directly into Government service. Five strikes were settled and no serious labor trouble resulted. It seemed marvelous that no disaster occurred in this plant. Time and again enemies attached time bombs to powder cars on their way to the munition plant. These cars were all stopped on an outside siding and searched, sometimes as many as thirty in one night. One time a bomb was found and two sticks of dynamite. A great deal of oily waste was found, which was no doubt attached in the hope that it might be set afire and so cause destruction of the car. There were two hundred and ten arrests made under charge of disorderly conduct, and one hundred under charge of trespassing. In each of these cases a conviction was secured. About two hundred violators of the Selective Service Act were put under arrest, and, as has been stated, thirty-five members of the I. W. W. were removed from the premises. More than one hundred and ten Austrians and Hungarians were discharged, and about two hundred aliens sent to the Department of Justice for examination. Over 1,500 investigations of suspects were made by the League, largely of men whose names seemed to proclaim them of German extraction. The record of this plant is unique, it probably being the only plant that has had so low a record of fires, explosions and accidents in all the history of our war work. Guards often found people endeavoring to do damage. One such man had piled up scrap lumber and rags and was touching it off when fired upon by the guard. Two other attempts were made to destroy another one of the buildings. Not content with protecting the property from without, the A. P. L. even protected it from within. Charges were made of extravagant prices paid by the Government, a fact which strongly indicated graft somewhere. A corporation had made a bid to furnish boxes at $450 each, delivered. This bid was refused. Volunteer workers were called on to make these boxes. The work was done on Sunday, double time being paid—each man receiving $14 a day—and even with such labor charges, it was found the boxes could be turned out at $17.25! This particular expenditure of money was stopped by the artless Ordnance Department. One or two chiefs were dismissed on the strength of reports from the A. P. L. of inefficiency, graft and irregularities. This, then, all too briefly and lamely done in review, is the story of Philadelphia, which operated one of the very best amateur detective agencies the world has ever seen and which was a credit not only to Philadelphia itself but to every operative of the A. P. L. wherever he was located in the United States.
