 common goose. 



96. Tame ducks [Anas hoschas), as wtII as geese, are kept by 

 the naturalized Portuguese and by the Musselmans, but not by 

 the Hindoos. Perhaps both these domestic birds were introduced 

 from Europe. I did not see Anas hoschas wild.

 both single and in flocks on every piece of water in the country,
