"I have what I consider a better plan," continued Gridley. "There are twenty-seven of us left. In the event of absolute necessity, twelve men can operate the ship. That will leave fifteen to form a new searching party. Leaving me out, you would have fourteen, and after you have heard my plan, if you decide upon sending out such a party, I suggest that Lieutenant Dorf command it, leaving you, Captain Zuppner, and Hines to navigate the ship in the event that none of us returns, or that you finally decide to set out in search of us." "But I thought that you were not going," said Zuppner. "I am not going with the searching party. I am going alone in the scout plane, and my advice would be that you send out no searching party for at least twenty-four hours after I depart, for in that time I shall either have located those who are missing or have failed entirely." Zuppner shook his head, dubiously. "Hines, Dorf and I have discussed the feasibility of using the scout plane," he said. "Hines was very anxious to make the attempt, although he realizes better than any of us that once a pilot is out of sight of the O-220 he may never be able to locate it again, for you must remember that we know nothing concerning any of the landmarks of the country in the direction that our search must be prosecuted." "I have taken all that into consideration," replied Gridley, "and I realize that it is at best but a forlorn hope." "Let me undertake it," said Hines. "I have had more flying experience than any of you with the possible exception of Captain Zuppner, and it is out of the question that we should risk losing him." "Any one of you three is probably better fitted to undertake such a flight than I," replied Gridley; "but that does not relieve me of the responsibility. I am more responsible than any other member of this party for our being where we are and, therefore, my responsibility for the safety of the missing members of the expedition is greater than that of any of the rest of you. Under the circumstances, then, I could not permit anyone else to undertake this flight. I think that you will all understand and appreciate how I feel and that you will do me the favor to interpose no more objection." It was several minutes thereafter before anyone spoke, the four seeming to be immersed in the business of sipping their coffee and smoking their cigarettes. It was Zuppner who broke the silence. "Before you undertake this thing," he said, "you should have a long sleep, and in the meantime we will get the plane out and have it gone over thoroughly. You must have every chance for success that we can give you." "Thank you!" said Gridley. "I suppose you are right about the sleep. I hate to waste the time, but if you will call me the moment that the ship is ready I shall go to my cabin at once and get such sleep as I can in the meantime."
