THREE:It may be noticed that the carriages of some lathes move on what are termed V tracks which project above the top of lathe frames, and that in other lathes the carriages slide on top of the frames with a flat bearing. As these two plans of mounting lathe carriages have led to considerable discussion on the part of engineers, and as its consideration may suggest a plan of analysing other problems of a similar nature, I will notice some of the conditions existing in the two cases, calling the different arrangements by the names of flat shears and track shears.Just outside Tongres I met a fleet of Red Cross cars loaded with wounded. Cavalry escorted them. I was stopped and ordered to go back, as they expected the Belgians to attack Tongres.

THREE:"Why, the corner house," Isidore cried. "Forty of these notes form part of the money taken from the body of that poor murdered fellow in the corner house. Here they are--190793 to 190832. Now which of you was it who came here tonight with these particular notes in your pocket?"

THREE:The beastly scenes which I witnessed in the glaring, scorching heat benumbed me, and I looked on vacantly for a long time. At last I went back and called at St. Hadelin College, the Head of which I had visited already once or twice. The building was still undamaged.

"I promise nothing. You are in no position to dictate terms. Sit down and tell me the history of the forgery."We find the same theory reproduced and enforced with weighty illustrations by the great historian of that age. It is not known whether Thucydides owed any part of his culture to Protagoras, but the introduction to his history breathes the same spirit as the observations which we have just transcribed. He, too, characterises antiquity as a scene of barbarism, isolation, and lawless violence, particularly remarking that piracy was not then counted a dishonourable profession. He points to the tribes outside Greece, together with the most backward among the Greeks themselves, as representing the low condition from which Athens and her sister states had only emerged within a comparatively recent period. And in the funeral oration which he puts into the mouth of Pericles, the legendary glories of Athens are passed over without the slightest allusion,69 while exclusive prominence is given to her proud position as the intellectual centre of Greece. Evidently a radical change had taken place in mens conceptions since Herodotus wrote. They were learning to despise the mythical glories of their ancestors, to exalt the present at the expense of the past, to fix their attention exclusively on immediate human interests, and, possibly, to anticipate the coming of a loftier civilisation than had as yet been seen.The next morning I got up early, having been unable to sleep. I realised already that my task was difficult, dangerous, and full of responsibility, for I had to find out and communicate to the public the truth about events, which would be related as beautiful or horrid, according to the interests of my informants. It was dangerous, because I might meet with the same fate that seemed to have been inflicted on so many civilians already.
