They crossed the island, passing the chestnut trees as they did so. Under one of the trees Dave picked up a letter. It was addressed to Nicholas Jasniff, General Delivery, Rockville.
"Jasniff must have dropped this when he was nutting," said Dave, as he and the others looked at the address.
"What is in it?" asked Phil. "It's open; read it."
"Would that be fair, Phil?"
"I think so. Jasniff is an enemy, not a friend. It may contain some clew to his doings, and if there is anything underhanded going on we can let the authorities know."
Dave took out the single sheet that the envelope contained. On it was written, in a sprawling, heavy hand, the following:
"My Dear Jasniff:
"I got your leter and I wil do all I can to help you pervided you wil help me on that bussines I meantioned to you. I know we both can make money and hardly anny risks. Beter not come to the office but meet me at Dunns on the River.
"Yours afectenately,
"Dr. H. Montgomery."
