THE FAUNA OF THE FRONT.

Chief among the fauna of the Front is, of course, the Bosch, a subterranean animal of unpleasant habits, which is now classed as vermin. He has been so thoroughly dealt with elsewhere that I shall leave him on one side, and confine my few observations to smaller and pleasanter creatures. The remaining fauna of the Front are (1) mice; (2) rats; with a few interesting extras, furred and feathered, which deserve more serious treatment than I can give them.

At home the mouse is regarded with contemptuous annoyance as a petty but persevering thief; while the rat commits his grosser depredations in an atmosphere tinged with horror. Out here it is different, for we are perforce neighbours. Indeed, we bipeds are in a sense trespassers upon the domain of the subterranean peoples. At home one seldom sees a rat or mouse save from above, and to look down upon anything is invariably to misjudge it. But here we share the hospitality of the underground and meet its freehold tenants on a level.

From the earth walls of the sanctuary where this small tribute is written mice look down upon our table with its newspaper cover, diffidently waiting for us to finish our meal and permit them to dine. We regard them as shy visitors—though are we not billeted on them?—not as sneaking thieves, and by the light of our candles perceive how sleek, bright-eyed, neat-handed and agile they are. In one dug-out I know a certain mouse who will drop on your shoulder and sit there a while in the friendliest manner, trying in his tiny modest way to play the host. Up above, in the open air, they are to be seen in swarms sharing our watchfulness. This gun-shaken valley is honeycombed with their little round funk-holes, into which they flash at any sudden noise. It is merely going downstairs where we are all at home.

The social instincts of the rat are less highly developed. His visible visits to the mess are rarer, but we overhear his conversation in his tunnels that open on our shelves, the patter of his pink feet across the canvas overhead, and the muscular squirming of his body in some tight place about the sandbag wainscot. Like a friendly dog he trots about your dug-out by night, bumping with trustful carelessness against the fragile legs of your rustic bed. You hear him crooning to himself or a pal, in his content—a placid, complacent little sound very different from the grating squeak or squeal of the unhappy Ishmaels you used to know. Certainly he will help himself to a little cake, if such a thing is to be had, for he feels at home, as he doubtless wishes you to do. If you do not care to share your dainties, you can hang them from the roof.

In the trenches themselves the rat is almost a domestic animal. Town rats are lean, persecuted and vicious; nobody loves them. But those who hobnob with us here are fed, like our Army, on Army rations, together with more than their share of private luxuries, and consequently are stout and contented-looking, and display none of the ill-bred and disconcerting haste of the hereditary fugitive of our drains and cellars. If you happen to stand still and silent for a few moments, you will hear some cheery old rascal come sniffing and grunting along the parapet, not so much in search of food as to enjoy the air—or so his manner would indicate.

Between the Army and these other dwellers in earths and burrows there must henceforth be a bond of true sympathy.
