"But I hardly see how I am to——" began Mr. Holmes.
I told him what to do.
"But surely," he said, "they will know better than that."
"No, they won't," I said. "Neither of them knows anything about it, really. Come, Mr. Holmes, it is for a good cause."
"Very well," he said. "Perhaps the end justifies the means. We will see what we can do."
"Good man," I said. "Children unborn will bless your name for this day's work."
I took him to the dining-room, where Margery and John were sitting.
"Here is Mr. Holmes," I said.
They both made a dash at him.
"Mr. Holmes," said John, "we seek your aid. You have a wide and deep knowledge of geography—that is botany, and you shall settle a problem that is ruining my home."
