WHO WAS THE HERO?
Bobby did not lose his head.

After his manner in emergencies, he thought quickly, and acted instantly, and now his bewilderment was for only a moment.
Seizing the harpoon which Jimmy had dropped upon the ice, he gave a yell that brought Skipper Ed to the water's edge in a hurry, and when Skipper Ed came running down Bobby had already thrown off his _netsek_ and his mittens and was knotting the loose end of the harpoon line around his waist.

Grasping the harpoon, he cast it upon the main ice, with the command: "Grab it, and hold it!" "My God!" gasped Skipper Ed.

"What has happened?
Where is Jimmy?
Where is Partner ?" "In there! Stand by and help!" directed Bobby, who had not taken his eyes off the dark water where Jimmy had disappeared, save for the fleeting instant when he cast his harpoon to Skipper Ed.
Presently Jimmy, hampered by his _netsek_, weakly struggled to the surface, already apparently overcome by the awful cold of the plunge.
Bobby saw him and instantly sprang after him, seized him about the waist and held him with the desperation of one who fights with death.

A moment's struggle followed and then both lads went down.
Skipper Ed now comprehended Bobby's suddenly formulated plan of rescue, and he pulled with all his strength upon the line, and as he pulled Bobby, still grasping Jimmy about the body, rose again to the surface, and Skipper Ed giving impetus to the line, drew them to him, seized them and quite easily drew them upon the ice.
Jimmy had already lost consciousness and Bobby was so overcome by the shock that he could scarcely speak, and Skipper Ed, lifting Jimmy into his arms, ran with him to the _igloo_, calling to Bobby as he did so: "Come! Run! Run, or you'll freeze!" Bobby tried to run--tried very hard--but he fell.
