Mr. Darwin has shown that, among the lower Vertebrata, the female commonly gives the preference to “the most vigorous, defiant, and mettlesome male,”—a taste the origin of which is easily accounted for by the theory of natural selection. A similar instinctive appreciation of manly strength and courage is found in women, especially in the women of savage races. In a song, communicated by Mr. Schoolcraft, an Indian girl gives the following description of her ideal:— “My love is tall and graceful as the young pine waving on the hill—And as swift in his course as the noble stately deer—His hair is flowing, and dark as the blackbird that floats through the air—And his eyes, like the eagle’s, both piercing and bright—His heart, it is fearless and great—And his arm, it is strong in the fight.”[1524] A tale from Madagascar tells of a princess whose beauty fascinated all men. Many princes fought to obtain possession of her; but she refused them all, and chose a lover who was young, handsome, courageous, and strong.[1525] The beautiful Atalanta gave herself to the best runner;[1526] and the hero suitors of the Finnish myths had to undergo difficult trials to prove their courage.[1527] “When a Dyak wants to marry,” says Mr. Bock, “he must show himself a hero before he can gain favour with his intended.” He has to secure a number of human heads by killing men of hostile tribes; and the more heads he cuts off, the greater the pride and admiration with which he is regarded by his bride.[1528] The demands of the Sàkalàva girls of Madagascar are less cruel. When a young man wishes to obtain a wife, his qualifications, according to Mr. Sibree, are tested thus:—“Placed at a certain distance from a clever caster of the spear, he is bidden to catch between his arm and side every spear thrown by the man opposite to him. If he displays fear or fails to catch the spear, he is ignominiously rejected; but if there be no flinching and the spears are caught, he is at once proclaimed an accepted ‘lover.’” It is said that a similar custom prevailed among the Bétsiléo, another Madagascar tribe.[1529] Among the Dongolowees, as we are informed by Dr. Felkin, if two men are suitors for a girl, and there is a difficulty in deciding between the rivals, the following method is adopted. The fair lady has a knife tied to each forearm, so fixed that the blade of the knife projects below the elbow. She then takes up a position on a log of wood, the young men sitting on either side with their legs closely pressed against hers. Raising her arms, the girl leans forward, and slowly presses the knives into the thighs of her would-be husbands. The suitor who best undergoes this trial of endurance wins the bride, whose first duty after marriage is to dress the wounds she has herself inflicted.[1530] Speaking of the natives on the River Darling, Major T. L. Mitchell says that the possession of gins, or wives, appears to be associated
