MARETT If I am unable to deliver this lecture in person, it will be because I have to attend in Jersey to the excavation of a cave once occupied by men of the Glacial Epoch. Now these men knew how to keep a good fire burning within their primitive shelter; their skill in the chase provided them with a well-assorted larder; their fine strong teeth were such as to make short work of their meals; lastly, they were clever artisans and one may even say artists in flint and greenstone, not only having the intelligence to make an economic use of the material at their disposal, but likewise having enough sense of form to endow their implements with more than a touch of symmetry and beauty. All this we know from what they have left behind them; and the rest is silence. And now let us imagine ourselves possessed of one of those time-machines of which Mr. H. G. Wells is the inventor. Transported by such means to the Europe of that distant past, could we undertake to beat the record of those cave-men? Clearly, all will depend on how many of us, and how much of the apparatus of civilization, our time-machine is able to accommodate. If it were simply to drop a pair of us, naked and presumably ashamed, into the midst of the rigours of the great Ice Age, the chances surely are that the unfortunate immigrants must perish within a week. Adam could hardly manage to kindle a fire without the help of matches. Eve would be no less sorely troubled to make clothes without the help of a needle. On the other hand, if the time-machine were as capacious as Noah's Ark, the venture would undoubtedly succeed, presenting no greater difficulty than, let us say, the planting of a settlement in Labrador or on the Yukon. Given numbers, specialized labour, tools, weapons, books, domesticated animals and plants, and so forth, the civilized community would do more than hold its own with the prehistoric cave-man, devoid of all such aids to life. Indeed, it is tolerably certain that, willingly or unwillingly, our colonists would soon drive the ancient type of man clean out of existence. On the face of it, then, it would seem that we, as compared with men of Glacial times, have decidedly 'progressed'. But it is not so easy to say off-hand in what precisely such progress consists.
