A JOUENEY IN BEAZIL, 



entrance of an igarap^, which here opens into the river, and 

 which looked most tempting with the morning shadows 

 darkening its cool recesses. As the boatmen had not been 

 very successful in fishing, I proposed we should put their 

 services to better use and row up this inviting stream. To 

 this day, though I have become accustomed to these forest

 we approached them, however cautiously, they vanished 

 like lightning either under the water or into some crevice 

 near by. Notwithstanding their nimbleness, however, Mr. 

 Agassiz succeeded in making a considerable collection. 

 We saw also an immense army of caterpillars, evidently fol-
