'There can be no doubt whatever, ' said Mr. Phillipps, 'that my theory is the true one; these flints are prehistoric fish-hooks.''I dare say; but you know that in all probability the things were forged the other day with a door-key.''Stuff!' said Phillipps; 'I have some respect, Dyson, for your literary abilities, but your knowledge of ethnology is insignificant, or rather non-existent. These fish-hooks satisfy every test; they are perfectly genuine.''Possibly, but as I said just now, you go to work at the wrong end. You neglect the opportunities that confront you and await you, obvious, at every corner; you positively shrink from the chance of encountering primitive man in this whirling and mysterious city, and you pass the weary hours in your agreeable retirement of Red Lion Square fumbling with bits of flint, which are, as I said, in all probability, rank forgeries.'Phillipps took one of the little objects, and held it up in exasperation.'Look at that ridge, ' he said. 'Did you ever see such a ridge as that on a forgery?'Dyson merely grunted and lit his pipe and the two sat smoking in rich silence, watching through the open window the children in the square as they flitted to and fro in the twilight of the lamps, as elusive as bats flying on the verge of a dark wood.'Well, ' said Phillipps at last, 'it is really a long time since you have been round. I suppose you have been working at your old task.''Yes, ' said Dyson, 'always the chase of the phrase. I shall grow old in the hunt. But it is a great consolation to meditate on the fact that there are not a dozen people in England who know what style means.''I suppose not; for the matter of that, the study of ethnology is far from popular. And the difficulties! Primitive man stands dim and very far off across the great bridge of years.''By the way, ' he went on after a pause, 'what was that stuff you were talking just now about shrinking from the chance of encountering primitive man at the corner, or something of the kind? There are certainly people about here whose ideas are very primitive.''I wish, Phillipps, you would not rationalize my remarks. If, I recollect the phrases correctly, I hinted that you shrank from the chance of encountering primitive man in this whirling and mysterious city, and I meant exactly what I said. Who can limit the age of survival? The troglodyte and the lake-dweller, perhaps representatives of yet darker races, may very probably be lurking in our midst, rubbing shoulders with frock-coated and finely draped humanity, ravening like wolves at heart and boiling with the foul passions of the swamp and the black cave. Now and then as I walk in Holborn or Fleet Street I see a face which I pronounce abhorred, and yet I could not give a reason for the thrill of loathing that stirs within me.''My dear Dyson, I refuse to enter myself in your literary "trying-on" department. I know that survivals do exist, but all things have a limit, and your speculations are absurd. You must catch me your troglodyte before I will believe in him.''I agree to that with all my heart, ' said Dyson, chuckling at the ease with which he had succeeded in 'drawing' Phillipps. 'Nothing could be better. It's a fine night for a walk, ' he added taking up h
