There are yet other ants, such as the workerless Anergates, in which the degradation of slaveholding has gone yet further. These wretched creatures are the formican representatives of those Oriental despots who are no longer even warlike, but are sunk in sloth and luxury, and pass their lives in eating bang or smoking opium. Once upon a time, Sir John Lubbock thinks, the ancestors of Anergates were marauding slaveowners, who attacked and made serfs of other ants. But gradually they lost not only their arts but even their military prowess, and were reduced to making war by stealth instead of openly carrying off their slaves in fair battle. It seems probable that they now creep into a nest of the far more powerful slave ants, poison or assassinate the queen, and establish themselves by sheer usurpation in the queenless nest. 'Gradually,' says Sir John Lubbock, 'even their bodily force dwindled away under the enervating influence to which they had subjected themselves, until they sank to their present degraded condition—weak in body and mind, few in numbers, and apparently nearly extinct, the miserable representatives of far superior ancestors maintaining a precarious existence as contemptible parasites of their former slaves.' One may observe in passing that these wretched do-nothings cannot have been the ants which Solomon commended to the favourable consideration of the sluggard; though it is curious that the text was never pressed into the service of defence for the peculiar institution by the advocates of slavery in the South, who were always most anxious to prove the righteousness of their cause by most sure and certain warranty of Holy Scripture.

[BIG ANIMALS]

'The Atlantosaurus,' said I, pointing affectionately with a wave of my left hand to all that was immortal of that extinct reptile, 'is estimated to have had a total length of one hundred feet, and was probably the very biggest lizard that ever lived, even in Western America, where his earthly remains were first disinhumed by an enthusiastic explorer.'

'Yes, yes,' my friend answered abstractedly. 'Of course, of course; things were all so very big in those days, you know, my dear fellow.'

'Excuse me,' I replied with polite incredulity; 'I really don't know to what particular period of time the phrase "in those days" may be supposed precisely to refer.'

My friend shuffled inside his coat a little uneasily. (I will admit that I was taking a mean advantage of him. The professorial lecture in private life, especially when followed by a strict examination, is quite undeniably a most intolerable nuisance.) 'Well,' he said, in a crusty voice, after a moment's hesitation, 'I mean, you know, in geological times ... well, there, my dear fellow, things used all to be so very big in those days, usedn't they?'

I took compassion upon him and let him off easily. 'You've had enough of the museum,' I said with magnanimous self-denial. 'The Atlantosaurus has broken the camel's back. Let's go and have a quiet cigarette in the park outside.'

But if you suppose, reader, that I am going to carry my forbearance so far as to let you, too, off the remainder of that geological disquisition, you are certainly very much mistaken. A discourse which would be quite unpardonable in social intercourse may be freely admitted in the privacy of print; because, you see, while you can't easily tell a man that his conversation bores you (though some people just avoid doing so by an infinitesimal fraction), you can shut up a book whenever you like, without the very faintest or remotest risk of hurting the author's delicate susceptibilities.

The subject of my discourse naturally divides itself, like the conventional sermon, into two heads—the precise date of 'geological times,' and the exact bigness of the animals that lived in them. And I may as well begin by announcing my general conclusion at the very outset; first, that 'those days' never existed at all; and, secondly, that the animals which now inhabit this particular planet are, on the whole, about as big, taken in the lump, as any previous contemporary fauna that ever lived at any one time together upon its changeful surface. I know that to announce this sad conclusion is to break down one more universal and cherished belief; everybody considers that 'geological animals' were ever so much bigger than their modern representatives; but the interests of truth should always be paramount, and, if the trade of an iconoclast is a somewhat cruel one, it is at least a necessary function in a world so ludicrously overstocked with popular delusions as this erring planet.
