IN THE PRIMEVAL FOREST. 271

 their escape; the apes on the tops of the trees, being 

 frightened by the crash, join their cries to those of the 

 larger animals; this arouses the tribes of birds, who build 

 their nests in communities, and thus the whole animal

 English feet) in breadth. On the naked rocks which formed
