"But behold a very strange and new fashion of them [cucumbers] in Campane, for there you shall have abundance of them come up in forme of a Quince. And as I heare say, one of the channced so to grow first at a very venture; but afterwards from the seed of it came a whole race and progenie of the like, which therefore they call Melonopopones, as a man would say, the Quince-pompions or cucumbers"--Pliny, Nat. Hist., Holland's translation, book xix, c.5 The word cucumis used in the original of this passage embraces many of the cucurbitaceae, but the context shows that here means the cucumber. The physical revolutions thus wrought by man have not indeed all been destructive to human interests, and the heaviest blows he has inflicted upon nature have not been wholly without their compensations. Soils to which no nutritious vegetable was indigenous, countries which once brought forth but the fewest products suited for the sustenance and comfort of man--while the severity of their climates created and stimulated the greatest number and the most imperious urgency of physical wants--surfaces the most rugged and intractable, and least blessed with natural facilities of communication, have been brought in modern times to yield and distribute all that supplies the material necessities, all that contributes to the sensuous enjoyments and conveniences of civilized life. The Scythia, the Thule, the Britain, the Germany, and the Gaul which the Roman writers describe in such forbidding terms, have been brought almost to rival the native luxuriance and easily won plenty of Southern Italy; and, while the fountains of oil and wine that refreshed old Greece and Syria and Northern Africa have almost ceased to flow, and the soils of those fair lands are turned to thirsty and inhospitable deserts, the hyperborean regions of Europe have learnod to conquer, or rather compensate, the rigors of climate, and have attained to a material wealth and variety of product that, with all their natural advantages, the granaries of the ancient world can hardly be said to have enjoyed. Observation of Nature. In these pages it is my aim to stimulate, not to satisfy, curiosity, and it is no part of my object to save my readers the labor of observation or of thought. For labor is life, and Death lives where power lives unused. [Footnote: Verses addressed by G. C. to Sir Walter Raleigh.--Haklutt, i., p. 608.]
