at, time is not constant even in
the same individual. How many hours are shorter to you than others? How
many days have been almost interminable? No, instead of being constant,
there is nothing more inconstant than time."

"Haven't you confused two different issues?" suggested the Big Business
Man. "Granted what you say about the slightly different rate at which
different individuals live, isn't it quite another thing, how long time
seems to you. A day when you have nothing to do seems long, or, on the
other hand, if you are very busy it seems short. But mind, it only
_seems_ short or long, according to the preoccupation of your mind. That
has nothing to do with the speed of your progress through life."

"Ah, but I think it has," cried the Chemist. "You forget that we none of
us have all of the one thing to the exclusion of the other. Time seems
short; it seems long, and in the end it all averages up, and makes our
rate of progress what it is. Now if any of us were to go through life in
a calm, deliberate way, making time seem as long as possible, he would
live more years, as we measure them, than if he rushed headlong through
the days, accomplishing always as much as possible. I mean in neither
case to go to the extremes, but only so far as would be consistent with
the maintenance of a normal standard of health. How about it?" He turned
to the Doctor. "You ought to have an opinion on that."

"I rather think you are right," said the latter thoughtfully, "although
I doubt very much if the man who took it easy would do as much during
his longer life as the other with his energy would accomplish in the
lesser time allotted to him."

"Probably he wouldn't," smiled the Chemist; "but that does not alter the
point we are discussing."

"How does this apply to the world in the ring?" ventured the Very Young
Man.

"I believe there is a very close relationship between the dimensions of
length, breadth, and thickness, and time. Just what connection with them
it has, I have no idea. Yet, when size changes, time-rate changes; you
have only to look at our own universe to discover that."

"How do you mean?" asked the Very Young Man.

"Why, all life on our earth, in a general way, illustrates the
fundamental fact that the larger a thing is, the slower its
time-progress is. An elephant, for example, lives more years than we
humans. Yet how quickly a fly is born, matured, and aged! There are
exceptions, of course; but in a majori
