"Yes; it won't be very pleasant," said Lamson, whose rather gentle and retiring nature had become completely transformed under the influence of the gigantic possibilities which were now at his disposal. "But suppose they get their ships up to Port Adelaide?--it's rather curious, by the way, that it should have the same name as that Frenchwoman, who, I suppose, is by this time about our most dangerous and determined enemy--but suppose they get them there, and begin knocking the works about with big guns. Suppose," he went on, with something like a shudder, "a shell bursts in the absorber, where are we? And, mind you, if they come they'll bring Fargeau with them; and if they took us prisoners or killed us, he would have material enough here to make another one--and he would know how to do it. No, no, Vandel; if I have to defend the works I'll do it. My whole life and soul are here now, and no Frenchman or Russian sets foot inside here while I'm alive, unless he comes as a prisoner." "But look here," said Austin; "couldn't you paralyse 'em? Why not set the engines to work, and mop up this world's soul, or whatever you call it, right away, so that their engines should break down long before they got here, and just freeze them out." "That, my dear Austin," replied the doctor, "is a rather more hasty remark than I should have expected you to make. Don't you see that if we were to start the engines, and cut off our American communications, as would be necessary, we should not only paralyse the expedition, we should also paralyse the whole of Canada and the United States, cut off our communications with England, and make it impossible for our friends to communicate with us, or for them to come here--as they are doing this month." "Guess I spoke a bit too soon," said Austin. "That's so; and, of course, we couldn't do it." The doctor continued his walk up and down the room for a few moments longer, then stopped and said suddenly, "No; but I'll tell you what we can and will do if there's going to be any of this sort of foul play about. The president and all our friends will be much safer here than in any other part of the world, for if we have to starve the world out they'll be all right here. Wire to your uncle; say that we have received his message and are acting upon it, and tell him to bring the whole party here with the utmost speed; call it a pleasure-trip or a tour of inspection, or what they please, but they must come at once, and, above all, they must get here before these so-called Polar expeditions." "That's the talk, doctor," exclaimed Austin; "you've got right down on to it this time. I'll fix that up in the code and send it right away."
