164 A JOURNEY IN BRAZIL. 



surprise he had given us. The creek led by a de*tour back 

 into the river, a few rods above the landing where our 

 steamer lay. Our friendly boatman left us at the stair- 

 way with a cordial good-by, and many thanks from us at 

 parting. 



We left our landing early this morning, and at about 

 half past ten turned into the main Amazons. Thus far 

 we have been in what is called the Para river, and the 

 branches connecting it with the Amazons proper. The pro-

 is half as large as Ireland. I add here a second letter from 

 Mr. Agassiz to Mr. Pimenta Bueno, giving a short summary

MON CHER AMI : Je suis extenue* de fatigue, mais je ne 

 veux pas aller me reposer avant de vous avoir crit un 

 mot. Hier soir nous avons obtenu vingt-be^t especes de 

 poissons a Gurupd, et ce matin, cinquante-sept a Porto do 

 Moz, en tout quatre-vingt-quatre especes en moins de douze 

 heures et, sur ce nombre, il y en a cinquante et tine nou-

 ce qu'on m'apporte au. fur et a mesure que cela arrive ; et

Tout a vous, 



L. AGASSIZ.*
