 not have brought either one or the other of his 

 fellow- workers with him from his Asiatic home, to 

 aid him in his further advance in civilisation. 

 Hence the same phenomenon, as was shown above 

 to have occurred in Australia, has been repeated 

 here, even though in a less striking manner. Even 

 at the beginning of our century, buffaloes (Bison 

 americanus) crossing the prairies were to be counted
