es," "The Rover Boys in the Mountains,"
and now the volume before you, which relates the adventures of the
three brothers, and some of their friends and enemies, on the sea
and on a number of far away islands, where, for a time, all lead a
sort of Robinson Crusoe life.

In writing this tale I had in mind not alone to please my young
readers, but also to give them a fair picture of life on the ocean
as it is to-day, in distinction to what it was years ago, and also
to acquaint the boys and girls with some of the beauties of those
mid-ocean lands which are generally, so strange to all of us. The
boys see much that is new, novel, and pleasing--new fruits, new
flowers, new animals--and have often to use their wits to the utmost,
to get themselves out of serious difficulty and also to make
themselves, and those under their protection, comfortable.

Once again I thank my young friends for the interest they have shown
in my previous stories. I trust that all who peruse this volume will
find it equally to their liking.

Affectionately and sincerely yours, ARTHUR M. WINFIELD.

in the habit of taking care of ourselves."

"Sam is joking," came from Dick Rover. "Still we might get lost here
as well as in New York or any other large city."

"Boston is the place to get lost in," said Tom Rover. "Got streets
that curve in all directions. But let us go on. Where is the hotel?"

"I'm sure I don't know," came from Sam Rover.

"Cab! carriage! coupe!" bawled a cabman standing near. "Take you
anywhere you want to go, gents."

"How much to take the three of us to the Oakland House?"

"Take you there for a dollar, trunks and all."

"I'll go you," answered Dick Rover. "Come on, I'll see that you get
the right trunks."

"I think we are going to have some good times while we are on the
Pacific coast," observed Tom Rover, while he and Sam were waiting
for Dick and the cabman to return.

"I shan't object to a good time," replied Sam. "That is what we came
for."

"Before we go back I am going to have a sail up and down the coast."

"To be sure, Tom. Perhaps we can sail do
