PKEFAOE. 



THE "Chapter in tlie History of Ants" 

 was originally contributed to Harper's New 

 Monthly Magazine. It grew out of my ob- 

 servations of the habits of the slave-making 

 ants (Formica sanguinea) of New Jersey. 



The paper on " The Harvesting-Ants of 

 Florida " was published in Lippincotfs Mag- 

 azine, and its appearance in this form is due 

 to the kind permission of the proprietors of 

 that publication.
