Following the crowd, Tom and Jack came to a side street, and one look down it showed the havoc wrought by the German engine of death. The shell, of what kind or calibre could not be even guessed, had fallen on top of an establishment where a number of women and girls were employed. And many of these had been killed or wounded. There were heart-rending scenes, which it is not good to dwell upon. But, even in the terror and horror, French efficiency was at the fore.

Ambulances were summoned, a guard was thrown about the building, and the work of aiding the injured and tenderly carrying out the dead was begun. A vast and excited throng increased in size about the building that had been hit and there was much excitement for a time.

Tom and Jack managed to get to a place where they could get a view of the havoc wrought to the structure itself, and the first thing that impressed them was mentioned by Jack, who said:

"They didn't use a very big shell, or there wouldn't have been such comparatively slight material damage done."

"The force was mostly expended inside the building," suggested Tom.

"Even so, if it had been a big shell, the kind they fired at Verdun and Liège, there'd be a crater here big enough to put a church in. As it is, only the two top stories are wrecked."

"That's right," agreed Tom. "I wonder what sort of explosive they are using? Must have been one from a bombing aeroplane."

"No, monsieur," interrupted a gendarme who was standing near. "Pardon, for speaking," he went on, with a salute, "but there was no airship observed over Paris at all. The shell came out of the clear sky."

"But it couldn't have," insisted Jack, in reply to this policeman. "If the Germans are firing on Paris they must have some place from which to shoot their gun. Either on the ground or from an airship."

"It was not an airship," insisted the gendarme. "Excuse me for insisting this to one who is in the air service," and he pointed with pride to the uniform the boys wore, "but I have seen several air raids, and I know! There was no airship seen, or I would have blown the alarm," and he motioned to his whistle which he carried for that purpose.
