 and white, with a crown of bright yellow and orange. 

 At this place we had no opportunity of studying them 

 at close range, but I mention the bird because of a 

 peculiar habit which one individual dis[)layed, namely, 

 the art of fishing. This particular Derby was the only 

 one of its species which frecpiented our camp, and here 

 the solitary bird spent much of each morning, unmo-

 in their own trade. Like the kingfishers, the Derby 

 perched u])on a rock and watched the eddies, and then 

 dived with all his might two or tliree times in succes-

 self more than three consecutive times, for his plumage 

 became water-soaked, and he then Hew heavily to a 

 sun-lit branch to spread himself to the sun. After dry- 

 ing he was at it again. It would be interesting to know 

 if, when a bird of such unusual habits mates and raises 

 a brood of young, tliis knowledge would in any way 

 be imparted to its offspring. 



Everywhere in the cliffs above us were caves, some 

 large, and many small, and toward evening, or in fact
