The captain was a widower with one child, a girl of fifteen.

The girl, whose name was Viola, said she would like to go up the coast to new lands.

But she would like Mrs.Cromwell, or some other lady, to go along.
Persuaded by Bob, Mrs.Cromwell said she would undertake the trip, and before they knew it, all arrangements were made.
The _Dart_, as the yacht was named, was sent to San Francisco for stores, and three days later Bob and Mrs.Cromwell and Jack Larmore left Sea Cove, and left it forever! It is not the purpose of this tale to tell of all that happened ere the _Dart_ put to sea on that memorable voyage up the coast to Alaska.
For awhile all went well on board.

But one day there was trouble among the crew.

The trouble grew worse and three of the fellows had to be put into irons.
They were let go later on, but ever after they showed their ugliness only too plainly.
Bob and Jack were not idle while on board.
