seven o'clock
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 ca n'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 .
