Autumn comes to the sea with a fresh blaze of phosphorescence, when every wave crest is aflame. Here and there the whole surface may glow with sheets of cold fire, while below schools of fish pour through the water like molten metal.

Nothing is wasted in the sea; every particle of material is used over and over again, first by one creature, then by another. And when in spring the waters are deeply stirred, the warm bottom water brings to the surface a rich supply of minerals, ready for use by new forms of life.

There is one quality that characterizes all of us who deal with the sciences of the earth and its life - we are never bored.

The 'control of nature' is a phrase conceived in arrogance, born of the Neanderthal age of biology and philosophy, when it was supposed that nature exists for the convenience of man.

Then the song of a whitethroat, pure and ethereal, with the dreamy quality of remembered joy.

We cannot have peace among men whose hearts find delight in killing any living creature.

Science is part of the reality of living; it is the what, the how, and the why of everything in our experience.
