In the idea of that solar extinction there are extraordinary imaginative possibilities, and M. Tarde must have exercised considerable restraint to prevent their running away with him and so jarring with the ironical lightness of his earlier passages. The conception of the sun seized in a mysterious, chill grip and flickering from hue to hue in the skies of a darkened, amazed and terrified world, could be presented in images of stupendous majesty and splendour. There arise visions of darkened cities and indistinct, multitudinous, fleeing crowds, of wide country-sides of chill dismay, of beasts silent with the fear of this last eclipse, and bats and night-birds abroad amidst the lost daylight creatures and fluttering perplexed on noiseless wings. Then the abrupt sight of the countless stars made visible by this great abdication, the thickening of the sky to stormy masses of cloud so that these are hidden again, the soughing of a world-wide wind, and then first little flakes and then the drift and driving of the multiplying snow into the dim illumination of lamps, of windows, of street lights lit untimely. Then again, the shiver of the cold, the clutching of hands at coats and wraps, the blind hurrying to shelter and the comfort of a fire--the blaze of fires. One sees the red-lit faces about the fires, sees the furtive glances at the wind-tormented windows, hears the furious knocking of those other strangers barred out, for, "we cannot have everyone in here". The darkness deepens, the cries without die away, and nothing is left but the shift and falling of the incessant snow from roof to ground. Every now and then the disjointed talk would cease altogether, and in the stillness one would hear the faint yet insistent creeping sound of the snowfall. "There is a little food downstairs," one would say. "The servants must not eat it.... We had better lock it upstairs. We may be here--for days." Grim stuff, indeed, one might make of it all, if one dealt with it in realistic fashion, and great and increasing toil one would find to carry on the tale. M. Tarde was well advised to let his hand pass lightly over this episode, to give us a simply pyrotechnic effect of red, yellow, green and pale blue, to let his people flee and die like marionettes beneath the paper snows of a shop window dressed for Christmas, and to emerge after the change with his urbanity unimpaired. His apt jest at the endurance of artists' models, his easy allusion to the hardening effects of fashionable decolletage, is the measure of his dexterous success; his mention of hotel furniture on the terminal moraines of the returning Alpine glaciers, just a happy touch of that flavouring of reality which in abundance would have altogether overwhelmed his purpose.
