MAN'S DIRECTION-SENSE 147

 would settle down and live quite contentedly until, 

 when another bad spell in the weather occurred after 

 six or twelve months, he would disappear again, and 

 this state of things continued as long as he lived.

We know that animals are capable of visualising 

 past scenes in this way. I have given instances of this 

 faculty and the delusions it gives rise to, in writing
