"A mountebank!" from all.
"Yes."
"Did he have an ape with him?"
"No! He was quite alone. He did not come in to make merry, but to get a bill changed. While he was there he was observed to scrutinize the place very closely."
"But he did not go into your vault?"
"No! He took his change and went peaceably out."
"Then, why should you suspect him?" insisted Donald, casting a knowing glance at the other boys.
"Because, an hour later, he came in again and said that one of the bills we gave him as change was a counterfeit."
"Was it?"
"No, it was not, although it was an old issue. The teller who waited upon him had no recollection of ever having seen the bill before, but rather than have a scene, we gave him another bill for it."
