"Ugh!" half grunted Walter, with no very cheerful heart, for the prospect before him, if Jack were to be ill. Jack was far from well, when the lights were turned aglow, and Cora came in to see him. It seemed to be a return of his old malady, brought on by an excess of work and worry.

There was little sleep for any of them the rest of the night, for Cora insisted upon sitting up to look after Jack, and Walter made himself up a bunk in the dining compartment, being ready on call.

Toward morning Cora's brother sank into an uneasy slumber under the influence of a sedative, but he awoke at seven o'clock and seemed feverish.

"We must have a doctor from the island," decided Cora, as she saw her brother's condition. "We can't take any chances."

The Danish physician who came out in the boat heartened them up a little by saying it was merely a relapse, and that Jack would be much better after a few days' rest.

"Just stay here with him, or anchor a little farther out," was his suggestion. "The sea breezes will be the best medicine for him. I can't give him any better. Just let him rest until he gets back his nerve."

This advice they followed. But there were anxious nights, and for
three of them Walter and Cora divided the task of sitting up with
Jack. Joe generously offered to do his share, as did Bess, Belle and
Inez, but Cora would not let them relieve her.

So they lingered off the coast of St. Croix until the fever left
Jack, departing from his weakened body, but making his mind at rest.
Then he began to mend.
