"Is that the way they are usually arranged?" inquired Drummond.
"Yes—the grille bars are of tempered steel and the openings between them are too small to permit anyone to put his hand through. Therefore, as we are somewhat pressed for space, we stack them up right along the outer wall of the grille and then work back. It saves time and labor in bringing them in."
"Is this the way the door of the grille ordinarily hangs?"
Bosbyshell inspected it a moment before he replied.
"Yes," he said. "It appears to be all right. It was purposely made to swing clear of the floor and the ceiling so that it might not become jammed. The combination and the use of the seal prevents its being opened by anyone who has no business in the grille."
"And the seal was intact when you came in yesterday afternoon?"
"It was."
"Thanks," said Drummond; "that was all I wanted to know," and he made his way upstairs with a smile which seemed to say that his vacation in the Maine woods had not been indefinitely postponed.
Once back in the director's office, the government operative asked permission to use the telephone, and, calling the Philadelphia office of the Secret Service, requested that three agents be assigned to meet him down town as soon as possible.
"Have you a record of the home address of the people employed in the Mint?" Drummond inquired of the director, as he hung up the receiver.
