In the private bar of the tavern the boys were alone long enough to make the exchange, and then Dick sent Bob ahead and told him to wait in the churchyard for him or some one wearing his own uniform.

"You are the captain now, Bob," with a laugh, "but I don't know who will be the lieutenant yet. That will depend."

Dick then went over to Stone street, where he entered a little shop kept by a draper, to whom he said:

"I want an ordinary suit of clothes, Mr. Towns. I am watching a spy and I think it just as well not to be in uniform."

"I see, Captain. You are wearing the lieutenant's coat now."

"You are very observant," smiling. "I will leave it here and send one of the boys for it."

"Very good, Captain. Step into the wareroom and take what you wish."

The wareroom was no bigger than the shop, but the different suits were hanging about the sides, and Dick quickly selected one not likely to attract much attention, and put it on, leaving the uniform behind. On Whitehall street Dick met one of the boys, Phil Waters by name, and directed him to go to the draper's and put on Bob's coat over his own, the young lieutenant being of a heavier build. As Phil did not have his musket with him, the change was easily effected, and no one not knowing him would suspect that he was not the lieutenant.

"Go and meet Bob," Dick said, "and talk about anything but matters of importance. Do not recognize me and watch the man whom you see observing you and Bob."

"All right, Captain," and Phil went away to make the change.
