my family."

"That's all that really matters," a chorus of voices echoed.

"We'd better not bother about anything else unless we find we
can't get back. Concentrate on getting back," one man stated more
explicitly.

"Look here," said Arthur incisively. "You've a family, and so have a
great many of the others in the tower, but your family and everybody
else's family has got to wait. As an inside limit, we can hope to
begin to work on the problem of getting back when we're sure there's
nothing else going to happen. I tell you quite honestly that I think
I know what is the direct cause of this catastrophe. And I'll tell
you even more honestly that I think I'm the only man among us who
can put this tower back where it started from. And I'll tell you
most honestly of all that any attempt to meddle at this present time
with the forces that let us down here will result in a catastrophe
considerably greater than the one that happened to-day."

"Well, if you're sure--" some one began reluctantly.

"I am so sure that I'm going to keep to myself the knowledge of what
will start those forces to work again," Arthur said quietly. "I
don't want any impatient meddling. If we start them too soon God
only knows what will happen."
