266 THE BOTANY OF CHRISTMAS ISLAND. 



Betel nuts with the husk on were swallowed by the 

 hornbill but it vomited up the seed. Naturally this fruit is 

 not eaten by any animal so far as I am aware. Rambutans 

 (JSfephelium) it only pecked and sucked not swallowing the seed. 



It would appear from these observations that these birds 

 would only carry the seed for a distance which could be 

 covered by them in 8 hours or a little more, so that in con- 

 veying seeds from say Java to Christmas Island about 300 

 miles the birds must make the passage in a comparatively few 

 hours.
