CHAP. X. SLAVE-MAKING ANTS F. SANGUINEA. 329 



pup se. I then traced the expedition back to the spot 

 from whence I first saw them set out ; which, according 

 to my steps, was about 156 feet from -the negro for-

(332.) The blood-coloured or sanguine ant (Formica 

 sanguined Lat.) is the second species of the slave- 

 making race, whose history has thus been given by 

 Huber. It requires, as before intimated, a distinct no- 

 tice, from possessing many peculiarities not found in 

 the rufous sort. On the 15th of July, at ten in the 

 morning, our indefatigable author observed a small band 

 of these ants sally forth from their city, and march 

 rapidly towards one of those inhabited by the negroes, 

 around which it dispersed. The inhabitants, rushing 

 out in crowds, attacked them, and took several prisoners : 

 this seemed to check their proceedings ; for those who 

 escaped made no further advance, apparently waiting 

 for reinforcements ; nor did they long wait in vain. 

 Small detachments kept frequently arriving ; and, thus 

 strengthened, they turned the blockade of the city into 

 a siege, and once more advanced, previously detaching 

 more couriers to their city for large supplies of warriors: 

 these spread a general alarm ; and a large reinforcement 

 immediately set out to join the besieging army. Yet, 

 rendered prudent by their former defeat, they did not 

 then immediately begin the assault. In the mean time, 

 almost all the negroes, coming out of their fortress, 

 formed themselves, in front, into a compact body about 

 two feet square, and thus awaited the attack. Frequent 

 skirmishes were the prelude to the general action, which 

 was begun by the negroes. Long before success ap- 

 peared dubious, they carried off their pupae, and heaped 

 them up at the entrance of their nest, on the opposite 

 side to that of the field of battle. The young females, 

 also, fled to the same quarter. The assailants at length 

 rushed upon the negroes, and, attacking them on all 

 sides, force them to retreat. Thus beaten, the negroes
