230 SCIENCE SKETCHES. 
no man ever saw alive. But still Favosites lay in 
the ground and waited. 
And the long, long summer passed by, and the 
autumn and the Indian summer. At last the win- 
ter came, and it snowed and snowed, and it was so 
cold that the snow did not go off till the Fourth of 
July. Then it snowed and snowed till the snow did 
not go off at all. And then it became so cold that 
it snowed all the time, till the snow covered the 
animals, and then the trees, and then the mountains. 
Then it would thaw a little, and streams of water 
would run over the snow. Then it would freeze 
again, and the snow would pack into solid ice. So 
it went on snowing and thawing and freezing, till 
nothing but snow-banks could be seen in Wisconsin, 
and most of Indiana was fit only for a skating-rink. 
And the animals and plants which could get away, 
all went south to live, and the others died and were 
frozen into the snow. 
So it went on for a great many years. I dare 
not tell you how long, for you might not believe 
me. Then the spring came, the south winds blew, 
and the snow began to thaw. Then the ice came 
sliding down from the mountains and hills, and 
from the north toward the south. It went on, 
tearing up rocks, little and big, from the size of a 
chip to the size of a house, crushing forests as you 
would crush an egg-shell, and wiping out rivers as 
you would wipe outa chalk-mark. So it came push- 
ing, grinding, thundering along, — not very fast, 
you understand, but with tremendous force, like a 
plough drawn by a million oxen, for a thousand feet 
of ice is very heavy. And the ice-plough scraped
