Not illustrated. 1879 Excerpt: ... to the bridge c, and once there, could hardly avoid arriving either at b or &'. I therefore modified the experiment as follows. I established and endowed an ant as before, imprisoning the friends who came with her. When she knew her way thoroughly, I allowed her to return to the nest on her own legs, but as soon as she emerged again I took her up on a slip of paper, and transferred her to the food. Under these circumstances, as will be seen, very few ants indeed ever found their way to the food. I began at 5.30, at which time the ant returned to the nest. At 5.34 she came out with no less than ten friends, and was then transferred to the food. The others wandered about a little, but by degrees returned to the nest, not one of them finding her way to the food. The first ant took some food, returned, and again came out of the nest at 5.39 with eight friends, when exactly the same happened. She again came out At 5.44 with 4 friends. At 6.44 with 0 friends. (39 journeys; 11 alone, 28 with 120 friends.) Thus, during these two hours, more than one hundred and twenty ants came out of the nest, in company with the one under observation. She knew her way perfectly, and it is clear that if she had been let alone, all these ants would have accompanied her to the store of food. Three of them were accidentally allowed to do so, but of the remainder only five found their way to the food; all the others, after wandering about a while, returned empty-handed to the nest. I conclude, then, that when large numbers of ants come to food they follow one another, being also to a certain extent guided by scent. The fact, therefore, does not imply any considerable power of intercommunication. There are, moreover, some circumstances which seem to point in an opposite direction....Read Less
