The chums went in at the broad door and saw a library at the right hand into which a tidy maid motioned them, with a smile. It was a large room, the walls masked by bookshelves, all filled so tightly that it did seem as though room for another book could not be found. But Mrs. Tellingham was not there.

Bending over the table, however, (and it was a large, leather-covered table with a great student lamp in the center, the shade of which threw a soft glow of light in a circle upon it) was a gentleman whose shoulders were very round and who seemed to be so near-sighted that his nose must have been within an inch or so of the book which he read. He was totally unconscious of the girls' presence, and he read in a half whisper to himself, like a child conning a lesson.

Ruth and Helen looked at each other, each thinking the same question. Could this be Doctor Tellingham, the great historian? They glanced again at the hoop-shouldered man and wondered what his countenance was like, for they could not see a feature of it as he read. But Ruth did notice one most surprising fact. The stooping gentleman wore a wig. It was a brown, rather curly wig, while the fringe of natural hair all around his head was quite white—of that yellowish-white that proclaims the fact that the hair was once light brown, or sandy in color. The brown wig matched the hair at one time, without doubt; but it now looked as though two gentlemen's heads had been merged in one—the younger gentleman's being the upper half of the present apparition.

For several minutes the chums stood timidly in the room and the old gentleman went on whispering to himself, and occasionally nodding his head. But at length he looked up, and in doing this he saw the girls and revealed his own countenance.

"Ah-ha!" he ejaculated, and stood upright. He was not a small man, but he was very bony. He had a big, long, smoothly-shaven face, on which his beard had sprouted in patches only, and these shaven patches were gray, whereas the rest of his face was smooth and dead-white. Indeed he had so much face, and it was so bald, that if the brown wig had chanced to tumble off Ruth thought that his appearance would have been actually terrifying.

"Ah-ha!" he said again, and smiled not unkindly. The thick spectacles he wore hid his eyes, however, and to look into his big face was like looking at the white wall of a house with the windows all shuttered. "You want something!"

He said it as though he had made a most profound discovery. Indeed, they found afterward that Doctor Tellingham always spoke as though he were pronouncing a valedictory oration, or something quite as important as that. The doctor never could say anything lightly. His mind was given up entirely to deep subjects, and it seldom strayed from his work.

"You want something," he repeated. "Stop! never mind explaining. I shouldn't be able to aid you. Mrs. Tellingham—my wife, my dears—will be here anon."

He at once bobbed down his head, revealing nothing to the eyes of the two girls but the brown wig and the hair that didn't match, and went on whispering to himself. Helen and Ruth exchanged glances and Helen had difficulty in keeping from laughing outright.

In a moment more Mrs. Tellingham came into the room. At close view Ruth saw that she was even more attractive than she had seemed at a distance. Her countenance was firm without being stern—the humor about the mouth relieved its set expression.
