MIGRATION 



enough," he wrote, " to raise one's indignation 

 to see so many vouchers from so many assertors 

 of this foolish and erroneous conjecture, which is 

 not only repugnant to reason, but to all the known 

 laws of nature." 



Some Modern Views. 



In looking further into this wide question, we 

 may fitly re-state the terms of the problems to be 

 solved. Where do the migrants come from ? 

 Whither do they go ? What are the motives which 

 lead them, season by season to leave their birth- 

 places, and to undertake arduous and constantly 

 fatal journeys to other lands ? And, finally 

 what is the nature of the mysterious power which 

 enables them to steer a true course across un- 

 known seas ? 



It is evident that the last question is immeasur- 

 ably the most important and fascinating of the 

 whole, for it leads at once to new realms of 

 thought, and with its solution might come the 

 discovery of a distinctly new sense to be added 

 to the familiar group by which human action is 

 commonly guided and controlled. 



In following Dr. Eagle Clarke's tracery of the 

 various lines of speculation on this question, we 

 come clearly to see how eagerly the world's thinkers 

 have at once attacked what may be described as 

 the chief of a set of phenomena, leaving the sub- 

 sidiary factors undefined, and, in many cases 

 unknown. If we may say so, it will stand per- 

 manently to Dr. Eagle Clarke's account that he 

 clearly recognised, on first undertaking his in- 

 quiry at the instance of John Cordeaux in 1880, 

 the existence of the vast mass of facts still to 

 be classified, and the mass perhaps greater still 

 as yet awaiting discovery.
