As Verva grew older and ceased to be persecuted by the children, she became beautiful in the unadorned manner of that early time. Her friendship with Why-Why began to embarrass the girl, and our hero himself felt a quite unusual shyness when he encountered the captive girl among the pines on the hillside. Both these untutored hearts were strangely stirred, and neither Why-Why nor Verva could imagine wherefore they turned pale or blushed when they met, or even when either heard the other's voice. If Why-Why had not distrusted and indeed detested the chief medicine-man, he would have sought that worthy's professional advice. But he kept his symptoms to himself, and Verva also pined in secret. These artless persons were in love without knowing it. It is not surprising that they did not understand the nature of their complaint, for probably before Why-Why no one had ever been in love. Courtship had consisted in knocking a casual girl on the head in the dark, and the only marriage ceremony had been that of capture. Affection on the side of the bride was out of the question, for, as we have remarked, she was never allowed so much as to see her husband's face. Probably the institution of falling in love has been evolved in, and has spread from, various early centres of human existence. Among the primitive Ligurian races, however, Why-Why and Verva must be held the inventors, and, alas! the protomartyrs of the passion. Love, like murder, "will out," and events revealed to Why-Why and Verva the true nature of their sentiments. It was a considerable exploit of Why-Why's that brought him and the northern captive to understand each other. The brother of Why-Why had died after partaking too freely of a member of a hostile tribe. The cave people, of course, expected Why-Why to avenge his kinsman. The brother, they said, must have been destroyed by a boilya or vampire, and, as somebody must have sent that vampire against the lad, somebody must be speared for it. Such are primitive ideas of medicine and justice. An ordinary brave would have skulked about the dwellings of some neighbouring human groups till he got a chance of knocking over a child or an old woman, after which justice and honour would have been satisfied. But Why-Why declared that, if he must spear somebody, he would spear a man of importance. The forms of a challenge were therefore notched on a piece of stick, which was solemnly carried by heralds to the most renowned brave of a community settled in the neighbourhood of the modern San Remo. This hero might have very reasonably asked, "Why should I spear Why-Why because his brother over-ate himself?" The laws of honour, however (which even at this period had long been established), forbade a gentleman when challenged to discuss the reasonableness of the proceeding.
