“Ah!” said his companion, answering his look of inquiry, “it is bone-dust; and now you may see where it comes from.”

Anthrops looked through the magnifying-glass, as he was directed, at the river itself, and found he could clearly see the sand at the bottom.  He was horrified at seeing the yellow surface strewn with human bones, bleached by long exposure to the running water.

“Alas!” he exclaimed, sorrowfully, “have so many noble youths perished in these treacherous waters?  That golden sand might be ruddy with the blood of its numerous victims!”

“Don’t be blaming the innocent waters, simple boy!” half sneered the philosopher.  “Lay the blame where it is due, upon the artful river-nixes.  Since the creation of the world, the stream has flowed tranquilly between these banks; and during that time do you not suppose that these fair alluring sprites have had opportunity to entice such silly boys as you into the cool green water there below?”

Anthrops gazed long into the still, cruel depths of the river, held spell-bound by a horrible fascination; at last he raised his head, and, drawing a long sigh of relief, exclaimed,—­

“Thank fortune, Haguna is no water-nix!”

“What!” cried the angry philosopher, “your mind still running upon that silly witch?  Can you learn no wisdom from the fate of other generations of fools, but must yourself add another to the catalogue?  She is more dangerous than the nixes:  the snares which they laid for their victims were cobwebs, compared to the one she is weaving for you.  You admire her hair, forsooth!  The silk of the Indian corn is a fairer color, spiders’ webs are finer, and the back of the earth-mole is softer; yet in your eyes nothing will compare with it.”

“The silk of the Indian corn is golden, but coarse and rough; the threads of the spider’s web are fine, but dull and gray; the satin hair of the blind mole is lifeless and stiff.  Let me go, old man!  I care nothing for your fancied dangers.  I shall row her to-day; that is pleasure enough.”  And he attempted to seize the unused oar.

“Once more, pause!  Reflect upon what you are leaving:  the pleasures of tranquil meditation, the keen excitements of science, the entrancing delights of philosophy.  All these you must abandon, if you leave me now.”

Anthrops hesitated a moment.

“How so?” he asked.

“He who is devoted to philosophy must share his soul with no other mistress.  No restlessness, no longing after an unseen face, no feverish anxiety for the love or approval of an earthly maiden must disturb the balanced calm of his absorbed mind”—­

“Herr Anthrops, Herr Anthrops, how you have forgotten your engagement!”

She was in a boat that had pushed up close to them unawares.  Some girls and young men occupied the bows.  Haguna was leaning over the stern and waving her hand to Anthrops.  So suddenly had she appeared, that it was as if she had risen out of the rippling river, and the ripples still seemed to undulate on her sunny hair and laughing dimpled face:  so fresh and bright and fair she seemed in that glad June morning.  What did it matter whether he reasoned rightly on any subject?
