and allow the animal freight to descend, which, then within a 

 comparatively short distance of the Bermudas, would seek the 

 nearest land by that instinctive impulse so characteristic of 

 these tribes, and aided perhaps by perfect calm or favor- 

 ing breeze, arrive at those distant isles, without encountering 

 the dangers, which, in the form of contrary winds, would most 

 certainly accompany an intentional migration to the islands ? 

 If our theory, however, be an incorrect one, as it may be, we 

 should indeed be glad if some one would lend a helping hand to 

 solve this question of a migration of tiny butterflies from the 

 American main to those small and remote isles, six hundred 

 miles away over the rolling waters of the trackless deep.
