Now, however, the peaks are in most cases only enormous rock-piles, the erosion having laid waste the country roundabout; or else they are mixtures of rock and earth rent by gorges through which furious torrents rush down immediately after each rainfall, submerging once fruitful plains with rock and infertile gully-dirt.
We did not see that place, although within half a day's journey, when we were at the horde of Syra, the court of their great emperor. Although otherwise infertile, this land is well adapted for the pasture of cattle.
From these facts; from the great difficulty of ascertaining the infertility of varieties in a state of nature, for a supposed variety if infertile in any degree would generally be ranked as species; from man selecting only external characters in the production of the most distinct domestic varieties, and from not wishing or being able to produce recondite and functional differences in the reproductive system; from these several considerations and facts, I do not think that the very general fertility of varieties can be proved to be of universal occurrence, or to form a fundamental distinction between varieties and species.
"If Darwin is right, it must be demonstrated that forms may be produced by selection, which, like the present sharply distinguished animal forms, are infertile, when coupled with one another, and this has not been done."
The soil was generally infertile, but the waters teemed with fish, while the high clay cliffs and the narrow promontories lent themselves readily to the Maori system of fortification. The safe anchorage which the Bay afforded early drew to it the whaling ships of Europe, especially as the harbour was accessible from the ocean in all weathers.
We admit the value of these arguments to their fullest extent; nay, we will go so far as to express our belief that experiments, conducted by a skilful physiologist, would very probably obtain the desired production of mutually more or less infertile breeds from a common stock, in a comparatively few years; but still, as the case stands at present, this "little rift within the lute" is not to be disguised nor overlooked.
To this class of troubles the only remedy is to breed from better stock. It is as much the trait of some birds to produce infertile eggs or chicks of low vitality as it is for others to produce vigorous offspring. The second class of ailments needs no discussion save that accorded it under the general discussions of the method of conducting the business.
He had tried the fertility of each ear, discarded those which proved weakly, or infertile, and his stand of corn for the four acres, which was now half hand high, was the best of any farmer between the Atterson place and town. But this corn was a hundred-and-ten-day variety.
The base idea of the attack and defence of trade may be summed up in the old adage, "Where the carcase is, there will the eagles be gathered together." The most fertile areas always attracted the strongest attack, and therefore required the strongest defence; and between the fertile and the infertile areas it was possible to draw a line which for strategical purposes was definite and constant.
Darwin's views, is quite unintelligible to me. As I have said in the seventh essay, the fact of evolution is to my mind sufficiently evidenced by palaeontology; and I remain of the opinion expressed in the second, that until selective breeding is definitely proved to give rise to varieties infertile with one another, the logical foundation of the theory of natural selection is incomplete.
