 probably introduced into England, and not more than three or four years ago.

The Times (London), October 12, 1887. 



Discusses fully the three topics: (1) When was the Hessian fly introduced into England? 

 (2) From what country was it introduced ? (3) What may be expected of it in future ? He 

 argues that it has been introduced within the last few years ; that it came into England from 

 Europe, and not from the continent of America, and decides that English farmers have little 

 to fear from the future injury of the species. He also discusses the general laws governing 

 the importation of animals and plants from Europe into America and vice versa.
