"And what might be his name?"

George recognized Mrs. Mack's voice.

"I have forgotten," said the man; "but they say he was a handsome lad, and scattered his money as if he expected it to grow again."

Then followed some conversation about the milk, and the door was closed. Mrs. Mack started as she saw her guest approaching.

"You had better stay in your room, Mr. Frothingham," she said. "That is my neighbor, the milkman, an inquisitive blackguard."

"Mrs. Mack," responded George, "I am the young man who is missing from the City Arms. They must not find me."

"Shure you're safe here. But what are you doing with the bowl, sir?" inquired the woman.

"I am going to read with it," said George. "Will you fill it with water?"

Mrs. Mack looked at him as if she thought he had taken leave of his senses, but she complied, and brought the bowl up to his room. In a few minutes more George was easily able to decipher the despatch. It ran as follows:

"To you,—Your number is four; initial B. Observe. We are glad to hear from our brother in New Jersey, and that he approves of the plan. It can be done. We are not suspected, and your arrival is most opportune. You have been seen by us; you are the young man for our purpose. It must be done on Friday night. A dinner will be given at a place to which you will receive an invitation. It is but a few steps from the river. After the dinner, cards will be proposed. Tables will be arranged in such a way that he whom we wish will be seated near the door. A note will arrive requesting his presence with the fleet. There will be no moon. A man-of-war's boat will be waiting; once in mid-stream, he will never reach the ships, for we know who mans the boat. The only difficulty will be to disarm suspicion of those who accompany him. They must be detained. You and another, who will be made known to you, will be playing at the farther table. You back him heavily with gold and lose your wager. This will keep the officers' attention. They will endeavor to stay after he is gone. When we have ten minutes' start pretend to be enraged, upset the table. There will be great confusion. The party will break up at once. Leave through the alley behind the house; go to Striker's Wharf. There you will find an able skiff. New Jersey is to the westward. We leave the rest to you. If we can keep enough of his friends from following him, it will be easy to accomplish our end of the undertaking. To-morrow at five o'clock be walking down the left-hand side of Johnson's Lane. Some one will pass you who will strike three times on the lid of his snuff-box. Turn and follow him. We hold no meetings, but he will give you some instructions. Final orders at the limb. You are number Four of Seven. Remember."
