NATURE IN MOTION. 59 



nobler, higher life among animals, moves restlessly round 

 the globe. Here also there is an incessant going and 

 coming, flying and pushing, an endless change of home, 

 to exchange a use*d-up past for a promising future. 



No class of animals, high or low, escapes entirely the 

 general law of movement, and if we read occasionally of 

 flights of storks and shoals of herrings, these are mere 

 anecdotes, nothing but single, detached features of that 

 unwearied life which moves in grand and restless masses 

 round the terrestrial globe. 



Of the earliest migrations of animals, even of those 

 whom man has bound up with his own existence, we 

 know but very little. History, which tells us nothing of 

 man's own first journeys, condescends not to speak of 

 beings less noble. We guess, rather than we know, that 

 the domestic animals at least left their common home 

 in the great centre of all earthly life, Upper India, to- 

 gether with the first migrating nations. We conclude this 

 mainly from the fact that the races of men separated at 

 a time when they were all shepherds. This we know 

 from Language; for in all idioms the words relating to 

 pastoral life are cognate words, whilst in other respects 

 the relationship is far more complicated and difficult to 

 trace. A remarkable instance of this connection is the 

 word "daughter" in German, "tochter," from the Greek 

 dvyarrip, which is in Sanscrit "duhitri," and there means 

 "milking woman," because we know that it was the cus- 

 tom of all pastoral nations to leave the milking of the 

 herd to the daughter of the owner. The animals them- 

 selves maintain a certain connection with their first home
