“Whenever I went strolling at night, he would produce his curious lights.  Sometimes they were fairly startling.  One fact I made out by accident, looking down from a high place.  They did not project from the laboratory.  He always worked in the open when the light was to be produced.  Once the experiment took a serious turn.  The lights had flickered and gone.  Dr. Schermerhorn had returned to his laboratory.  I came up the arroyo as he flung the door open and rushed out.  He was a grotesque figure, clad in an undershirt and a worn pair of trousers, fastened with an old bit of tarred rope in lieu of his suspenders, which I had been repairing.  About his waist flickered a sort of aura of radiance which was extinguished as he flung himself headforemost into the cold spring.  I hauled him out.  He seemed dazed.  To my questions he replied only by mumblings, the burden of which was: 

“‘I do not understand.  It is a not-to-be-comprehended accident.’  It appears that he didn’t quite know why he had taken to the water.  Or if he did, he didn’t want to tell.

“Next day he was as good as new.  Just as silent as before, but it was a smiling, satisfied silence.  So it went for weeks, for months, with the accesses of depression and anger always rarer.  Then came an afternoon when, returning from a stalk after sheep, I heard strange and shocking noises from the laboratory.  Strict as was the embargo which kept me outside the door, I burst in, only to be seized in a suffocating grip.  Of a sudden I realised that I was being embraced.  The doctor flourished a hand above my head and jigged with ponderous steps.  The dismal noises continued to emanate from his mouth.  He was singing.  I wish I could give you a notion of the amazement, the paralysing wonder with which....  No, you did not know Dr. Schermerhorn:  you would not understand....

“We polkaed into the open.  There he cast me loose.  He stopped singing and burst into a rhapsody of disjointed words.  Mostly German, it was—­a wondrous jumble of the scientific and poetic.  ‘Eureka’ occurred at intervals.  Then he would leap in the air.  It was weird, it was distressing.  Crazy?  Oh, quite.  For the time, you understand.  If any of us should suddenly become the most potent individual in the world, wouldn’t he be apt to lose balance temporarily?  One must make allowances.  There was excuse for the doctor.  He had reached the goal.

“‘Percy, you shall be rewarded,’ he said.  ’You haf like-a-trump-card stuck by me.  You shall haf riches, gold, what you will.  You are young; your blood runs red.  With such riches nothing is beyond you.  You could the ancient-tombs-of-Egypt explore.  It is open to you such collections-as-have-never-been-gathered to make.  What shall it be?  Scarabs?  Missals?  Prehistoric implements?  Amuse yourself, mein kind.  We shall be able the-bills-with-usurious-interest to pay.  What will you haf?’

“I said I’d like a vacation, if convenient.
