sonia sp.) about 25 feet high. The next day the nest was again 

 visited, and on climbing an adjoining tree two young birds were 

 visible stretching and sunning themselves. 



"The present year (1901) on June 29, I again made an 

 excursion to the same place but found the cabbage tree had fallen 

 down and that the birds had built in an adjoining and also most 

 inaccessible tree. However, the difficulties being overcome I found 

 it contained two eggs, hard set, which would have been hatched in 

 the course of a few days. 



" A month later on July 29, I found the birds had returned and 

 one egg was laid, and on August 3 there were two. The nest 

 was then photographed at a short distance, as owing to the sur- 

 roundings it could not be taken from far off, but the photograph (fig. 

 103) gives a good idea of its massive structure and of the enormous 

 amount of material utilised ; it measures about 5 feet across." 



The clutch evidently consists of two eggs only ; these are white 

 and somewhat rough, measuring about 3-0 x 2-25.
