There is every probability that these harvesting ants will be found all round the shores of the Mediterranean, but the only points at which I have positively heard of the existence of the habit besides Mentone, Cannes, and Marseilles, are Capri[34] and Algiers. I am indebted to Miss Forster for having, during a short visit to Algiers, devoted some time to watching the habits of the ants in a garden at that place. These observations were made in April last (1872), when the three following species were watched:-- [Footnote 34: Where a harvester, probably _Atta barbara_, has been observed by Mr. Buchanan White. See Appendix C.] (1) _Formica (Cataglyphis) viatica_, a large, long-legged, blackish ant, with orange-red and semi-transparent thorax, which never carried seeds, but lived on animal food, especially flies. (2) _Formica (Tapinoma) nigerrima_,[35] a rather small dusky ant, which brought in some seeds to its nest, but principally "animal food, flies, small worms," &c., and which did not carry the hemp and canary seed strewed in their path, though on one occasion when Miss Forster scattered some split hemp seed, they eagerly fastened upon the contents, and ate some on the spot, while they transported the greater part to their nest, and (3) _Atta barbara_, which, as on the Riviera, was a true and most active harvester, and eagerly seized upon the hemp and canary seed when these were placed in its way. [Footnote 35: Mr. Smith thinks that this ant is either _F. nigerrima_, of Nylander, or a new species, but it was not possible for him to pronounce with absolute certainty as he had only two specimens of workers from which to judge.] _Recapitulation and Concluding Remarks._ There are some points of interest suggesting openings for future observation, to which I will now allude, making at the same time a partial recapitulation of what has gone before. We have learned in the first place that the ancients had facts on their side when they said that the ant is one of the very few creatures which lays up supplies of food sufficient to last for months, or even perhaps, as Bochart says, for a whole year; and though we cannot quite accept the statement that "there is no animal except men, mice, and ants, that stores its food,"[36] they were right in saying that the habit is a most singular and interesting one. It is probable, however, that the old writers may have fallen into the error of supposing that all ants were harvesters, though the truth appears to be, that even in hot climates, it is only a very small number of species that are so. The fact that certain ants in Southern Europe do store large quantities of sound seed in damp soil, and check their tendency to germinate, may be thought to favour the possibility of the existence of those deeply hidden supplies of seed which, though they have never been detected, are popularly supposed to explain the sudden appearance of the crops of weeds on soil newly brought out from great depths.
