Without taking into account insects and such other "small deer,"--to quote Shakespeare's expression,--this fundamental principle of population will become at once apparent if we examine merely familiar instances of back-boned or vertebrate animals. The lowest vertebrates are clearly the fishes: and the true fishes have almost invariably gigantic families. A single cod, for example, is said to produce, roughly speaking, nine million eggs at a birth (I cannot pretend I have checked this calculation); but supposing they were only a million, and that one-tenth of those eggs alone ever came to maturity, there would still be a hundred thousand codfish in the sea this year for every pair that swam in it last year: and these would increase to a hundred thousand times that number next year; and so on, till in four or five years' time the whole sea would be but one solid mass of closely-packed cod-banks. We can see for ourselves that nothing of the sort actually occurs--practically speaking, there are about the same number of cod one year as another. In spite of this enormous birth-rate, therefore, the cod population is not increasing--it is at a standstill. What does that imply? Why, that taking one brood and one year with another, only a pair of cod, roughly speaking, survive to maturity out of each eight or nine million eggs. The mother cod lays its millions, in order that two may arrive at the period of spawning. All the rest get devoured as eggs, or snapped up as young fry, or else die of starvation, or are otherwise unaccounted for. It seems to us a wasteful way of replenishing the earth: but it is nature's way; we can only bow respectfully to her final decision.
The grain of wheat is a part of the flower of the wheat plant, which, when it becomes ripe, is easily separated. It contains a minute and rudimentary plant; and, when it is sown, this gradually grows, or becomes developed into, the perfect plant, with its stem, roots, leaves, and flowers, which again give rise to similar seeds. No mineral body runs through a regular series of changes of form and size, and then gives off parts of its substance which take the same course. Mineral bodies present no such development, and give off no seeds or germs. They do not reproduce their kind.
Twelve years elapsed between the subjugation of Latium and the commencement of the Second Samnite War. During this time the Roman arms continued to make steady progress. One of their most important conquests was that of the Volscian town of Privernum in B.C. 329, from which time the Volscians, so long the formidable enemies of Rome, disappear as an independent nation. The extension of the Roman power naturally awakened the jealousy of the Samnites; and the assistance rendered by them to the Greek cities of Palaeopolis and Neapolis was the immediate occasion of the Second Samnite War. These two cities were colonies of the neighboring Cumae, and were situated only five miles from each other. The position of Palaeopolis, or the "Old City," is uncertain; but Neapolis, or the "New City," stands on the site of a part of the modern Naples. The Romans declared war against the two cities in B.C. 327, and sent the Consul Q. Publilius Philo to reduce them to subjection. The Greek colonists had previously formed an alliance with the Samnites, and now received powerful Samnite garrisons. Publilius encamped between the cities; and as he did not succeed in taking them before his year of office expired, he was continued in the command with the title of _Proconsul_, the first time that this office was created. At the beginning of the following year Palaeopolis was taken; and Neapolis only escaped the same fate by concluding an alliance with the Romans. Meanwhile the Romans had declared war against the Samnites.
