The excerpt represents the core issue or deciding factor on which you must meditate, and is drawn from Madam How and Lady Why by Charles Kingsley: steam is always strong. And if you look at a railway engine,
still more if you had ever seen--which God forbid you should--a
boiler explosion, you would agree with me, that the strongest
thing we know of in the world is steam.
Now I think that we can explain almost, if not quite, all that we
know about earthquakes, if we believe that on the whole they are
caused by steam and other gases expanding, that is, spreading out,
with wonderful quickness and strength. Of course there must be
something to make them expand, and that is HEAT. But we will not
talk of that yet.
Now do you remember that riddle which I put to you the other day?-
