"We will meet again at three," said he with a friendly nod.

Richard took from his room Vogt's Physiological Letters, went into the garden, and buried himself in its contents.

CHAPTER V.

THE PROGRESSIVE PROFESSOR.

When Frank returned from the walk, he found a visitor at Frankenhöhe.

The visitor was an elegantly dressed young man, with a free, self-important air about him.

He spoke fluently, and his words sounded as decisive as though they came from the lips of infallibility. At times this self-importance was of such a boastful and arrogant character as to affect the observer disagreeably.

"It is now vacation, and I do not know how to enjoy it better than by a visit to you," said he.

"Very flattering to me," answered Frank. "I hope you will be pleased with Frankenhöhe."

"Pleased?" returned the visitor, as he looked through the open window at the beautiful landscape. "I would like to dream away here the whole of May and June. How charming it is! An empire of flowers and vernal delights."
