The long summer was over. For ages a tropical climate had prevailed over a great part of the earth, and animals whose home is now beneath the Equator roamed over the world from the far South to the very borders of the Arctics ... But their reign was over. A sudden intense winter, that was also to last for ages, fell upon our globe.

The study of Nature is intercourse with the highest mind. You should never trifle with Nature. At her lowest her works are the works of the highest powers, the highest something in the universe, in whichever way we look at it... This is the charm of Study from Nature itself; she brings us back to absolute truth wherever we wander.

I hail with joy- for I am a temperance man and a friend of temperance-I hail with joy the efforts that are being made to raise wine in the country. I believe that when you have everywhere cheap, pure, unadulterated wine, you will no longer have need for either prohibitory or license laws.

Embryology furnishes, also, the best measure of true affinities existing between animals.

A smattering of everything is worth little. It is a fallacy to suppose that an encyclopaedic knowledge is desirable. The mind is made strong, not through much learning, but by the thorough possession of something.

In 1847 I gave an address at Newton, Mass., before a Teachers' Institute conducted by Horace Mann. My subject was grasshoppers. I passed around a large jar of these insects, and made every teacher take one and hold it while I was speaking. If any one dropped the insect, I stopped till he picked it up. This was at that time a great innovation, and excited much laughter and derision. There can be no true progress in the teaching of natural science until such methods become general.

When chemists have brought their knowledge out of their special laboratories into the laboratory of the world, where chemical combinations are and have been through all time going on in such vast proportions,-when physicists study the laws of moisture, of clouds and storms, in past periods as well as in the present,-when, in short, geologists and zoologists are chemists and physicists, and vice versa,-then we shall learn more of the changes the world has undergone than is possible now that they are separately studied.
