“Easy enough to explain,” laughed Dick Davis. “Port authorities at Rio were good enough to order six motor boats for harbor purposes. My dad got the chance of building the boats at his yard at Bath. The Rio motor boats 189 are on board, down in the hold, and Ab and I are sent along to deliver the motor boats, put them in running order at Rio, and, if necessary, teach the natives how to run such craft.”

“Did you fellows know we were signaling you by wireless?” Joe was asking Ab Perkins. “Did you know that you were going to see us?”

“Didn’t know a blessed thing about it,” admitted Ab Perkins, almost sheepishly. “Dick and I were asleep in our stateroom. We were getting ready to come out on deck when we felt the old tub slackening speed. Then we came out to see what was happening. We looked over the rail, and—wow!”

Ab again seized Joe Dawson’s hand, giving it another mighty shake. Then the irrepressible Ab reached out for Tom’s hand, but Dick Davis was drawing Halstead up on deck.

Readers of the first volume of this series will remember both Ab and Dick well. They, too, were boys born near the Kennebec River, and took part in the stirring adventures narrated in The Motor Boat Club of The Kennebec, just before Tom and Joe left for the next scenes of their activities, as related in The Motor Boat Club at Nantucket and The Motor Boat Club off Long Island. Ab Perkins and Dick Davis were two of the most valued of the early members of the Club. 190

All in a twinkling, Tom Halstead was seized by an idea. He looked about for Powell Seaton, saw that gentleman talking with Captain Rawley, and caught the charter-man’s eye.

“See here, Mr. Seaton,” whispered Halstead, as soon as he had gotten his employer aside, “there’s no great need for me to go to Rio.”

“No?”

“Of course not. Give the papers to Dick Davis, with exact instructions as to who is to receive them at Rio Janeiro, and those papers will get into exactly the hands for which you intend them.”

“You feel certain of that, Halstead?” demanded Powell Seaton, his voice tremulous with anxiety.
