The desire for security, very marked in women, draws the weaker among them to men who, by their strength or ability, seem to offer protection and support. In time of war they count a warrior's scalps; in time of peace they hunt for genius or wealth. To the man in love the giving of gifts is a way of asserting his power. The penguin and the banker offer pebbles of varying brilliance to their respective loved ones. The finch presents twigs and leaves to its mate as the young man presents woolen threads in the form of carpets and curtains to his fiancee. The swallow and the woman begin to thing of the nest the moment they have chosen their males.
