 And yet it is the bott-fly of the Holy Ghost, unlistened to, that is the real cause of everything.

But the mob has no direction even in its destructive lust. The vengeful masses have direction. And it is no good trying to reason with them. The mass does not act by reason. A mass is not even formed by reason. The more intense or extended the collective consciousness, the more does the truly reasonable, individual consciousness sink into abeyance.

The herd instinct, for example, is of many sorts. It has two main divisions, the fear-instinct, and the aggressive instinct. But the vengeance instinct is not part of the herd instinct.

But consider the mode of communication of herd instinct. The communication between the individuals in a herd is not through the mind. It is not through anything said or known. It is sub-mental. It is telepathic.

Why does a flock of birds rise suddenly from the tree-tops, all at once, in one spring, and swirl round in one cloud towards the water? There was no visible sign or communication given. It was a telepathic communication. They sat and waited, and waited, and let the individual mind merge into a kind of collective trance. Then click!—the unison was complete, the knowledge or suggestion was one suggestion all through, the action was one action.

This so-called telepathy is the clue to all herd instinct. It is not instinct. It is a vertebral-telegraphy, like radio-telegraphy. It is a complex interplay of vibrations from the big nerve-centres of the vertebral system in all the individuals of the flock, till, click!—there is a unanimity. They have one mind. And this one-mindedness of the many-in-one will last while ever the peculiar pitch of vertebral nerve-vibrations continues unbroken through them all. As the vibration slacks off, the flock falls apart.

This vertebral telepathy is the true means of communication between animals. It is perhaps most highly developed where the brain, the mental consciousness, is smallest. Indeed the two forms of consciousness, mental and vertebral, are mutually exclusive. The highest form of vertebral telepathy seems to exist in the great sperm whales. Communication between these herds of roving monsters is of marvellous rapidity and perfection. They
