The latter was a young man of twenty-five perhaps, and, as we have said, was decidedly sallow and unhealthy-looking; in fact, natural good looks were marred not a little by his complexion. But with the one who had been addressed as Jim it was different. The young fellow was barely seventeen years of age, and his rosy cheeks displayed the fact that diving did not disagree with him. Then, too, his voice was so different. It was crisp and laughing, and anything but despondent; while, when he had rid himself of his diving weights and of his heavy boots, and was on his feet, one saw that he was of a good height, held himself well, and moved with the quick step that one might have expected from having seen him clamber from the depths of the ocean. But there was concern in his face when Sadie called him. "George don't feel over well, Jim," she called out. "He said a minute back that he was burning hot; now he's downright shivering." "Fever," said Jim promptly, taking his brother's hand. "Tom, there, just leave Sam and Ching to haul in the tackle. I want you." "Sah, what for? De master ill?" Even his smile was almost gone as he looked at George with eyes which were startled and wide open, for the happy-go-lucky Tom, so unused to sorrow or sickness, could tell at a glance that his young employer was anything but himself. "Get along and fetch a bed on deck," commanded Jim; "then rig a shelter over it. Best place it right aft; there's more room, and you'll be able to pull the awnings over better. George'll stay on deck; it's too hot down below." Pulling his diving suit off hurriedly, he helped his sister to disrobe the sick man; then, with Tom at George's head and Jim at his feet, they carried him aft and laid him on the bed already prepared. Sadie at once took her seat beside him, armed with a fan, while the negro, Tom, hastened to fetch water from the big canvas sack in which it was placed every day to cool. A strong dose of quinine was given to the sick man, and thereafter there was little to do but to watch him and tend to his immediate needs. "We'll get up anchor and make right off for Colon," said Jim, as he stood beside his sister, some little distance from the bed. "There's nothing down there to salve, and we're wasting time and money. Better get back and see if there isn't another job to be had. This salvage work ain't paying us at all. We're losing heavily. Guess we'll have to get back on to the land."
