Amber Waves Directory 04

One wife, however, does not suffice to fill the nest with eggs; and the stickleback is a firm believer in the advantages of large families. So, as soon as his first mate has laid all her spawn, he sets out once more in search of another. Thus he goes on until the home is quite full of eggs, bringing back one wife after another, in proportion to his success in wooing and fighting. For, like almost all polygamists, your stickleback is a terrible fighter. The males join wager of battle with one another for possession of their mates; in their fierce duels they make fearful use of the formidable spines on their backs, sometimes entirely ripping up and cutting to pieces their ill-fated adversary. The spines thus answer to the spurs of the gamecock or the antlers of the deer; they are masculine weapons in the struggle for mates. Indeed, you may take it for granted that brilliant colors and decorative adjuncts in animals almost invariably go with irascible tempers, pugnacious habits, and the practice of fighting for the possession of the harem. The consequence is, with the sticklebacks, that many males get killed during the struggle for supremacy, so that the survivors wed half a dozen wives each, like little Turks that they are in their watery seraglios. Only the most beautiful and courageous fish succeed in gaining a harem of their own: and thus the wager of battle tells in the end for the advantage of the race, by eliminating the maimed, the ugly, and the cowardly, and encouraging the strong, the handsome, the enterprising, and the valiant. This is nature's way of preventing degeneracy.
At Piriatingalini and Puchalini we found light cable suspension bridges, very shaky, which swung to and fro as you rode over them. Most of them were not more than four feet wide and had no parapet at all. I cannot say that I felt particularly happy when my mule--sure-footed, I grant--took me across, the bridge swinging, quivering, and squeaking with our weight on it, especially when we were in the middle. The rivers were extremely picturesque, with high mountains on either side, among which they wound their way in a snake-like fashion over a rocky bed, forming a series of cascades. We went that day 25 kil., and arrived at the _tambo_ of Azupizu, which was in charge of a deserter from the French navy. He was an extraordinary character. He had forgotten French, and had neither learnt Spanish nor the local language of the Campas Indians.
