and forced a steadying cup of bouillon upon him. Finally she asked gently what was distressing him, and waited anxiously for his reply, hoping to hear that Surama's treatment of the poor Tibetan had horrified and outraged him.

There was a note of fretfulness in his voice as he responded. "What's distressing me? Good God, Georgina, what _isn't_? Look at the cages and see if you have to ask again! Cleaned out--milked dry--not a cursed specimen left; and a line of the most important bacterial cultures incubating in their tubes without a chance to do an ounce of good! Days' work wasted--whole program set back--it's enough to drive a man mad! How shall I ever get anywhere if I can't scrape up some decent subjects?"

Georgina stroked his forehead. "I think you ought to rest a while, Al dear."

He moved away. "Rest? That's good! That's damn good! What else have I been doing but resting and vegetating and staring blankly into space for the last fifty or a hundred or a thousand years? Just as I manage to shake off the clouds, I have to run short of material--and then I'm told to lapse back again into drooling stupefaction! God! And all the while some sneaking thief is probably working with my data and getting ready to come out ahead of me with the credit for my own work. I'll lose by a neck--some fool with the proper specimens will get the prize, when one week more with even half-adequate facilities would see me through with flying colors!"

His voice rose querulously, and there was an overtone of mental strain which Georgina did not like. She answered softly, yet not so softly as to hint at the soothing of a psychopathic case. "But you're killing yourself with this worry and tension, and if you're dead, how can you do your work?"

Science is what must be served--science--the austere cause of human knowledge. I'm like the monkeys and birds and guinea-pigs I use--just a cog in the machine, to be used to the advantage of the whole. They had to be killed--I may have to be killed--what of it? Isn't the cause we serve worth that and more?"

Georgina sighed. For a moment she wondered whether, after all, this ceaseless round of slaughter really was worth while."But are you absolutely sure your discovery will be enough of a boon to humanity to warrant these sacrifices?" Clarendon's eyes
