CEARA. 465 
Brazilian steamers make the trip from Pernambuco to Cear& 
in two days. The nearest serra in which I have observed 
traces of ancient glaciers is reached from Ceara in one day 
on horseback. The best season for such a journey would be 
June and July, at the close of the rainy season, and before 
the great droughts of the dry season have began."
