, without going nearer. In this position they beat off all assaults of the besieged, until they feel themselves strong enough to advance to the attack. This attack scarcely ever fails, and has for its chief object the mastering of the entrances and outlets of the nest. A special troop guards each opening, and only allows such of the besieged to pass out as carry no pup . This man uvre gives rise to a number of comical and characteristic scenes. By this means the sanguine ants in a few minutes manage

results of his observations in a book of three hundred pages.2 These observations are for the most part confirmatory of those of Lincecum, and for this as well as for reasons to be deduced from the work itself, they deserve to be accepted as trustworthy, notwithstanding that in some cases they are provokingly incomplete. The following is an epitome of these observations. The ants clear away all the herbage above their nest in the form of a perfect circle, or 'disk,' 15 or 20 feet in diameter, by

of from four to six square yards; on examining the ants closely they are seen to move, not all together in one straightforward direction, but in variously spreading contiguous columns, now separating a little from the general mass, now reuniting with it. The margins of the phalanx spread out at times like a cloud of skirmishers from the flanks of an army. I was never able to find the hive of this species. [page] 121 MILITARY ANTS

Similarly Huber relates an observation of his own showing the duration of memory in bees. One autumn he put some honey in a window, which the bees visited in large numbers. During the winter the honey was taken away and the shutters shut. When they were again opened in the spring the bees returned, although there was no honey in the window. These two cases amply prove that the memory of bees is comparable with that of ants, which, as we have seen from analogous facts, also extends at least

far, therefore, from being at all affectionate, I doubt whether bees are in the least fond of one another. R aumur, however ('Insects,' vol. v., p. 265), narrates a case in which a hive-bee was partly drowned and so rendered insensible; the others in the hive carefully licked and otherwise tended her till she recovered. This seems to show that bees, like ants, are more apt to have their sympathies aroused by the sight of ailing or injured companions than by that of healthy companions in

which we have already noticed in the case of certain ants, a row of bees is formed, and the bits of moss passed from one to another along the line. There is a long passage to the nest, through which the moss has to be passed, and it is said that at the mouth of the tunnel a guard is stationed to drive away ants or other intruders. Wasps. These usually construct their nests of wood-dust, which they scrape off the weather-worn surfaces of boards, palings, c., and work into a kind of paper with

arriving at maturity: she therefore raised them from it in the manner I have described.2 Mr. Belt gives the following account of the intelligence which certain species of South American spiders display in escaping from the terrible hosts of the Eciton ants: Many of the spiders would escape by hanging suspended by a thread of silk from the branches, safe from the foes that swarmed both above and below. I noticed that spiders generally were most intelligent in escaping, and did not, like the cockroaches

type is functionally inferior to the invertebrate type, where this reaches its highest stage of evolution in the Hymenoptera. Emotions. Fish display emotions of fear, pugnacity; social, sexual, and parental feelings; anger, jealousy, play, and curiosity. So far the class of emotions is the same as that with which we have met in ants, and corresponds with that which is distinctive of the psychology of a child about four months old. I have not, however, any evidence of sympathy, which would be

no colonies of ants beneath this stone, and on digging a hole where it had lain, several burrows and worms were found. At Stonehenge, some of the outer Druidical stones are now prostrate, having fallen at a remote but unknown period; and these have become buried to a moderate depth in the ground. They are surrounded by sloping borders of turf, on which recent castings were seen. Close to one of these fallen stones, which was 17 ft. long, 6 ft. broad, and 28 1/2 inches thick, a hole was dug; and

already been remarked, by burrowing animals of many kinds, especially by ants. In countries where the summer is long and dry, the mould in protected places must be largely increased by dust blown from other and more exposed places. For instance, the quantity of dust sometimes blown over the plains of La Plata, where there are no solid rocks, is so great, that during the gran seco, 1827 to 1830, the appearance of the land, which is here unenclosed, was so completely changed that the inhabitants could

about 2 inches into the ground; more especially if we bear in mind that a good deal of the finest earth would have been washed by heavy rain from the castings ejected on the sloping border down to the level of the field. Some fresh castings were seen close to the stone. Nevertheless, on digging a large hole to a depth of 18 inches where the stone had lain, only two worms and a few burrows were seen, although the soil was damp and seemed favourable for worms. There were some large colonies of ants

large as the others; and two strong boys could together have rolled it over. I have no doubt that it had been rolled over at a moderately recent time, for it now lay at some distance from the two other stones at the bottom of a little adjoining slope. It rested also on fine earth, instead of partly on brick-rubbish. In agreement with this conclusion, the raised surrounding border of turf was only 1 inch high in some parts, and 2 inches in other parts. There were no colonies of ants beneath

was proved to be correct.' Depriving bees of their antenn has the effect of producing an even more marked bewilderment than results from this operation in the case of ants. A queen thus mutilated by Huber ran about in confusion, dropping her eggs at random, and appeared unable to take with precision the food that was offered her. She showed no resentment to a similarly mutilated stranger queen that was introduced: the workers also heeded not the mutilated stranger; but when an unmutilated
