Take a willow, or any like speedy growing plant newly rooted in a box
or barrel full of earth, weigh them all together exactly when the tree
begins to grow, and then weigh all together after the tree is increased
from its first rooting, to weigh a hundred pound weight more than when
it was first rooted and weighed; and you shall find this augment of the
tree to be without the diminution of one drachm weight of the earth.
Hence they infer this increase of wood to be from water of rain, or from
dew, and not to be from any other element; and they affirm, they can
reduce this wood back again to water; and they affirm also, the same
may be done in any animal or vegetable. And this I take to be a fair
testimony of the excellency of my clement of water.

The water is more productive than the earth. Nay, the earth hath no
fruitfulness without showers or dews; for all the herbs, and flowers, and
fruit, are produced and thrive by the water; and the very minerals are
fed by streams that run under ground, whose natural course carries
them to the tops of many high mountains, as we see by several springs
breaking forth on the tops of the highest hills; and this is also witnessed
by the daily trial and testimony of several miners.

Nay, the increase of those creatures that are bred and fed in the water
are not only more and more miraculous, but more advantageous to man,
not only for the lengthening of his life, but for the preventing of
sickness; for it is observed by the most learned physicians, that the
casting off of Lent, and other fish days, which hath not only given the
lie to so many learned, pious, wise founders of colleges, for which we
should be ashamed, hath doubtless been the chief cause of those many
putrid, shaking intermitting agues, unto which this nation of ours is now
more subject, than those wiser countries that feed on herbs, salads, and
plenty of fish; of which it is observed in story, that the greatest part of
the world now do. And it may be fit to remember that Moses appointed
fish to be the chief diet for the best commonwealth that ever yet was.

And it is observable, not only that there are fish, as namely the Whale,
three times as big as the mighty Elephant, that is so fierce in battle, but
that the mightiest feasts have been of fish. The Romans, in the height of
their glory, have made fish the mistress of all their entertainments; they
have had musick to usher in their Sturgeons, Lampreys, and Mullets,
which they would purchase at rates rather to be wondered at than
believed. He that shall view the writings of Macrobius, or Varro, may
be confirmed and informed of this, and of the incredible value of their
fish and fish-ponds.

But, Gentlemen, I have almost lost myself, which I confess I may easily
do in this philosophical discourse; I met with most of it very lately, and,
I hope, happily, in a conference with a most learned physician, Dr.
Wharton, a dear friend, that loves both me and my art of Angling. But,
however, I will wade no deeper into these mysterious arguments, but
pass to such observations as I can manage with more pleasure, and less
fear of running into error. But I must not yet forsake the waters, by
whose help we have so many known advantages.
