(Ch. 10)

July 11 /58/ saw in morning a body of about a score of F. sanguinea: from number thought nest was near: in afternoon found same body about ya 2 yards distant in contest with a body of F. nigra, of which nest was about 18 inches distant. The slave-takers had come across a high-road of F. nigra.— They were fighting I saw one F. sanguinea with slave in mouth & 2 clinging to his legs; these he killed: some which were in mouth escaped. I saw none fairly carried off.— I think they were a body of defeated slaves.— I then took pupæ from other nest of F. nigra & scattered on ground, they were most eagerly seized & carried about 15 yards. all in same track through thick heath to nest, which I could not find.—

July 12" In morning 8 A.M. no ants at Battle-field. 12° 30 plenty, apparently reconnoitering, & some small ones: I killed one of latter, & though some just seized it, none carried it away, which confirms my views that they even marauding & moreover very different.— far away [illeg] At last I fd. nest 29 yards distant very crooked path though all pit, in straight line much nearer.— In line of march old small nest is act of deserting winged individuals unhurt, being dragged to nest & some workers, which I do not understand & some slaves about p 9 I saw carried which were unhurt.— The carriers were evidently fearful of crossing path & like nursery-insects with children at a crossing made a rush.— I doubt about only big workers coming out when disturbed.—

Afternoon 4°-40'.— put some larvæ of F. nigra in path with the ants of pale yellow small kind, which commonly makes hemispheres on the common— & they certainly seem quite terrified at them: but ultimately carried away pupæ; immediately they carried away pupæ of the negro.— /over

If a second nest— small workers seemed exceptionally numerous; I dug into it & saw hardly one slave.— At first nest, when disturbed sometimes slave comes out; say at Moor Park.—

Slave-makers

July 13. Eras. kicked hillock & fd. 2 ants. black & yellow domiciled in same hillock, & so did I; when hillock kicked over, they fought.—

I took larvæ (specs. preserved) pupæ of these 2 Kinds & put them on battle-field; it seemed to me quite certain that slave-maker recognized earth in which the pupæ of the blacks were & greatly preferred their pupæ. but ultimately they took the others. I saw some take up & then drop the pupæ of yellow.—

Wednesday 14th. I have now seen here 5 nests— Black slaves in all.— Slaves defend nest, when seriously disturbed running up twigs, just like F. sanguinea,— The slaves, as well as F. sanguinea females the pupæ of F. sanguinea when nest is much disturbed— Slaves never, I think bring sticks or food.— (after repeated watching I do not believe small large workers come out more than small)
