 they, and so light in their gambols, that it would have been difficult to have 

 perceived them. Here I stopped, and killed first one, then two, and even 

 three, without the others appearing frightened ; but when most were 

 wounded they began to seek shelter, some concealing themselves behind 

 the thick branches, others descending to the ground ; but the greatest 

 number darting from the top of one tree to that of another. It was very 

 interesting to see a bough, when several of them leaped together on it, 

 bend under them, and the outermost Monkey drop to the ground, while 

 some cleared their way onward, and others were suspended in the air. 

 In the meantime I continued firing, and killed twenty-three in less than an 

 hour, and in the space of twenty fathoms, without one of them having
