on the plain-furnished parlour with its hot coffee and vin ordinaire as something warm and snug and comforting in a wet and slushy world. To the soldier on his trench-to-billets migration the wine-shop is what the tavern rest-house is to the caravan nomad of the East. One comes and goes in a crowd of chance-foregathered men, noticed or unnoticed as one wishes; amid the khaki-clad, be-putteed throng of one’s own kind one can be as unobtrusive as a green caterpillar on a green cabbage leaf; one can sit undisturbed, alone or with one’s own friends, or if one wishes to be talkative and talked to one can readily find a place in a circle where men of divers variety of cap badges are exchanging experiences, real or improvised.

Besides the changing throng of mud-stained khaki there is a drifting leaven of local civilians, uniformed interpreters, and men in varying types of foreign military garb, from privates in the Regular Army to Heaven- knows-what in some intermediate corps that only an expert in such matters could put a name to, and, of course, here and there are representatives of that great army of adventurer purse-sappers, that carries on its operations uninterruptedly in time of peace or war alike, over the greater part of the earth’s surface. You meet them in England and France, in Russia and Constantinople; probably they are to be met with also in Iceland, though on that point I have no direct evidence.

In the estaminet of the Fortunate Rabbit I found myself sitting next to an individual of indefinite age and nondescript uniform, who was obviously determined to make the borrowing of a match serve as a formal introduction and a banker’s reference. He had the air of jaded jauntiness, the equipment of temporary amiability, the aspect of a foraging crow, taught by experience to be wary and prompted by necessity to be bold; he had the contemplative downward droop of nose and moustache and the furtive sidelong range of eye-he had all those things that are the ordinary outfit of the purse-sapper the world over.

‘I am a victim of the war,’ he exclaimed after a little preliminary conversation.

‘One cannot make an omelette without breaking eggs,’ I answered, with the appropriate callousness of a man who had seen some dozens of square miles of devastated country-side and roofless homes.

‘Eggs!’ he vociferated, ‘but it is precisely of eggs that I am about to speak. Have you ever considered what is the great drawback in the excellent and most useful egg—the ordinary, everyday egg of commerce and cookery?’

‘Its tendency to age rapidly is sometimes against it,’ I hazarded; ‘unlike the United States of North America, which grow more respectable and self-respecting the longer they last, an egg gains nothing by persistence; it resembles your Louis the Fifteenth, who declined in popular favour with every year he lived—unless the historians have entirely misrepresented his record.’

‘No,’ replied the Tavern acquaintance seriously, ‘it is not a question of age. It is the shape, the roundness. Consider how easily it rolls. On a table, a shelf, a shop counter, perhaps, one little push, and it may roll to the floor and be destroyed. What catastrophe for the poor, the frugal!’

I gave a sympathetic shudder at the idea; eggs here cost 6 sous apiece.

‘Monsieur,’ he continued, ‘it is a subject I had often pondered and turned over in my mind, this economical malformation of the household egg. In our little village of Verchey-les-Torteaux, in the Department of the Tarn, my aunt has a small dairy and poultry farm, from which we drew a modest income. We were not poor, but there was always the necessity to labour, to contrive, to be sparing. One day I chanced to notice that one of my aunt’s hens, a hen of the mop-headed Houdan breed, had laid an egg that was not altogether so round-shaped as the eggs of other hens; it could not be called square, but it had well-defined angles. I found out that this particular bird always laid eggs of this particular shape. The discovery gave a new stimulus to my ideas. If one collected all the hens that one could find with a tendency to lay a slightly angular egg and bred chickens only from those hens, and went on selecting and selecting, always choosing those that laid the squarest egg, at last, with patience and enterprise, one would produce a breed of fowls that laid only square eggs.’
