PLANTS PROBABLY DISPERSED BY BIRDS. 



The number of plants locally dispersed by birds is undoubtedly very large ; and the 

 perfectly sound seeds ejected from the crops of carpophagous birds, which fly long distances, 

 prove the possibility of their being active agents in transporting seeds to distant, or even 

 perhaps very rarely indeed to remote shores. In Polynesia, for example, it is very 

 probable that birds have played an important part iu conveying certain seeds from island 

 to island ; but that birds ever carry seeds uninjured the enormous distances suggested by 

 Dr Guppy, for instance, seems to us improbable.

 p. 250: "Grisebach, Vegetation der Erde, ii. p. 49G, lays much stress on the wide
