 he was unable to discover its breeding-place. 



Mr. Barrington Brown (Canoe and (/amp Life, p. 265) writes: — 

 "Upon the sand-beaclies of the Takutu we saw numbers of Orinooco 

 geese [Chenalop^x jiihata) being very tame from not being molested 

 bv the Indians, who do not consider their flesh a fit article for 

 human food.^'
