A YOCXG NATURALIST. 343 



The neighborhood of the swnidero furnished us with a 

 dozen birds of different species; among others, several 

 tanagers peculiar to America, and a pair of pretty light- 

 brown cuckoos, with fan-shaped tails, which are merely 

 birds of passage in this locality. 



" When you are speaking of a bird, why do you often 

 say it belongs to Brazil, Guiana, or Peru, when you actually

" Because, at certain seasons of the year, many kinds of

And he showed us a handful of an herb called purslane. 



This plant, which grows in abundance in damp ground, 

 has red flowers, which close every evening and open again 

 in the morning. I gathered the fleshy leaves, while Su- 

 michrast, who had found a plant covered with seeds, show-
