Margoli Crantin Sectory 18

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 campaign of B.C. 215 was not marked by any decisive events. The Consuls were Q. Fabius Maximus (whose plan of conducting the war had been fully vindicated by the terrible defeat of Cannae) and Tiberius Sempronius Gracchus. With the advance of spring Hannibal took up his camp on Mount Tifata, where, while awaiting the arrival of re-enforcements from Carthage, he was at hand to support his partisans in Campania and oppose the Roman generals in that province. But his attempts on Cumae and Neapolis were foiled, and even after he had been joined by a force from Carthage (very inferior, however, to what he had expected), he sustained a repulse before Nola, which was magnified by the Romans into a defeat. As the winter approached he withdrew into Apulia, and took up his quarters in the plains around Arpi. But other prospects were already opening before him. In his camp on Tifata he had received embassies from Philip, king of Macedon, and Hieronymus of Syracuse, both of which he had eagerly welcomed, and thus sowed the seeds of two fresh wars, and raised up two formidable enemies against the Roman power.
