Dr. McCook, of Philadelphia, has been telling us about ants in Texas that sow, reap, and store grain in granaries. There are some, also, that keep stock :

" It has been stated by Sir John Lubbock that certain kinds of aphides are preserved by ants for purposes of the food afforded by a certain sweet secretion in the former, the eggs being carefully guarded and the young larvae fed and cherished until they ultimately attain their perfect form, when they served as contributions to the dietery of the ants".
