The wanderer who stands to-day in the desolate country of James Bay or Ungava is among the oldest monuments of the world. The rugged rock which here and there breaks through the thin soil of the infertile north has lain on the spot from the very dawn of time. Millions of years have probably elapsed since the cooling of the outer crust of the globe produced the solid basis of our continents.
On the other hand, there can be no doubt that the individuals of many natural species are either absolutely infertile if crossed with individuals of other species, or, if they give rise to hybrid offspring, the hybrids so produced are infertile when paired together.
We may be right, but we must be provably, demonstrably and overpoweringly right before we are justified in calling the dissentient a fool. I am one of those who believe firmly in the invincible nature of truth, but a truth that is badly put is not a truth, but an infertile hybrid lie.
In the occupation of focal areas the two ideas are even more inseparable, since most, if not all, such areas are on lines of communication that are common. It will suffice, therefore, to deal with the general aspect of the subject from the point of view of defence. It was in conformity with the distinction between fertile and infertile areas that our old system of trade defence was developed.
From a scientific point of view the results are quite striking. From the practical standpoint, however, the question is, whether the "Hawaii" and other fertile varieties are adequate to yield seedlings, which will surpass the infertile "Cheribon" cane.
But it is a very simple matter with which the reader, who is doubtless a better arithmetician than I am, may amuse himself, to estimate the number of married women of reproductive age in the community, and allowing anything in reason for illegitimate motherhood and nothing at all for infertile wives, to satisfy himself that the total cost which would be involved in the adequate care of motherhood, is a mere fraction of the national expenditure.
The only colour is given by the fan-like plants of the prickly-pear, whose flat, thick-lipped, pear-shaped leaves, stuck with thorns, and often extruding their reddish fruit from the edge, lend a dull green to the scene. This plant grows everywhere, like wild bush, to a man's height, covering the otherwise infertile soil, and the goats crop it.
Meanwhile, the fragments that remain of his own attempts in this direction are no considerable contributions. His Hints for an Essay on the Drama are jejune and infertile, when compared with the vigorous and original thought of Diderot and Lessing at about the same period. He wrote an Account of the European Settlements in America.
I must here notice a mechanical effect of the rapid flow of the torrent, which is of much importance in relation to the desolating action it exercises by covering large tracts of cultivated ground with infertile material. The torrent, as we have seen, shoots or rolls forwards, with great velocity, masses and fragments of rock, and sometimes rounded pebbles from more ancient formations.
But between species, in many cases, you cannot succeed in obtaining even the first cross: at any rate it is quite certain that the hybrids are often absolutely infertile one with another. Here is a feature, then, great or small as it may be, which distinguishes natural species of animals.
