The two girls, who understood this conversation much less than the "promenade" and the "na poo" of the Tommies, went up to the colonel, who talked to them paternally in his gruff way and got the "Caruso" record for them out of its pink cover.
"You have some weird ideas about animal psychology, Aurelle," said the doctor. "If you have observed nature, you would have proved, on the contrary, that the question of the numbers of mates is certainly not a question of arithmetic. With gnats, ten females are born to one male. Now gnats are not polygamous. Nine of those females die spinsters. It is only the old maids who bite us, from which one sees that celibacy engenders ferocity among insects as well as among women."
"I have known some charming old maids," said Aurelle.
"Indeed!" said the doctor. "But, however that may be, the number of married pairs varies simply according to the way the species feed. Rabbits, Turks, sheep, artists, and, generally speaking, all herbivorous creatures are polygamous; while foxes, Englishmen, wolves, bankers, and, generally speaking, all carnivorous animals are monogamists. That is because of the difficulty which carnivorous animals find in rearing their young until they are strong enough to kill for themselves. As for polyandry, it occurs in wretched countries like Thibet, where several men must unite forces to keep one wife and her progeny."
The howls of Caruso rendered all conversation impossible for a minute, then Aurelle said to Lucie:
"The other girls in the village will perhaps find it difficult to get husbands, it is true, but you and your sister need not worry; you are the prettiest, and you will soon have the richest father. You will have fine marriage portions."
"Yes, that’s true. Perhaps they will marry us for our money," said Berthe, who was modest.
"I should not care to be married for my money," said Lucie.
"Oh, strange creature!" said the doctor, "you would like to be loved for your face alone, that is to say, for the position in space of the albuminoids and fatty molecules placed there by the working of some Mendelian heredity, but you would dislike to be loved for your fortune, to which you have contributed by your labour and your domestic virtues."
