"Aut impendere viam, aut poscere causas."

But a wretched-looking Hoover it was that emerged from the Doctor's closet at two that afternoon and slunk back to the accustomed place at the foot of the room. Even Briggs had steered clear of him, and every one noted how Briggs flitted about from group to group during recess, his old-time "cheek" apparently vanished, his effrontery replaced by nervous appeal. He had seized on Shorty, as the boys turned out for recess, with eager question about Snipe, but the youngster impatiently shook him off and shot away, light of foot as he was heavy of heart, and the eyes of the others followed him as he turned into Twenty-fourth Street, for all seemed to know he was using his half-hour to speed to the Lawrences' for news of Snipe. Before the bell recalled them he was back, mournfully shaking his head, and they trooped up-stairs, low-voiced and disconsolate, Hoover slinking in alone, last of all, his hands in his pockets, his shoulders hunched, his eyes flitting nervously about. All through the half-hour the talk had been as to the possible cause of Snipe's mysterious withdrawal from the school and later and more mysterious disappearance. Everybody felt that John, the janitor, could tell something, even if it were only a lie—or a pack of lies, for John's veracity was a thing held up to scorn at the end of a hair. But John kept under the wing of some teacher and could not and would not be approached, and John looked white and scared. The Doctor came at the usual time, made the usual impressive pause at the doorway, pointed, as usual, to the usual foot of the class, who blinked and shifted rather more than ever. Then Pop removed his hat and strode with his usual deliberation to the closet, hung it on its peg, produced his gold-rimmed spectacles, and, as usual, wiped the glasses with his spotless cambric handkerchief as he looked over the notes and letters on his desk, while in subdued, half-hearted way the recitation went on. Then, with only a glance along the line of young faces, all studying him and none regarding Halsey, who at the moment had little Beekman on the rack, he signalled to Shorty, and the boy sprang to his side.

"Hear anything?" he asked, in undertone, as though he needed not to be told that Shorty had gone to inquire.

"No news, sir," said Loquax, with lips that twitched alarmingly. "Mrs. Lawrence will be here right after school."

"Then you stay. I may need you," said the Doctor, and pointed to the bench.

Five minutes later, after rapidly reading the brief missives on his desk, the Doctor arose, signalled to Hoover, ushered him into the lead-colored closet, followed and shut the door, from which quarter of an hour later Hoover emerged, as has been said, looking limp and woe-begone, and the moment school was over slunk away homeward without a word. By this time the First Latin was half mad with mingled curiosity and concern, when an elegantly dressed woman, followed by a manservant with a compact little parcel under his arm, appeared at the Fourth Avenue entrance, where the group still lingered, waiting for Shorty, and the whisper went round that it was Mrs. Lawrence, Snipe's aunt. The excitement rose to fever heat. Doremus and Satterlee, scouting about the avenue an hour later, declared that she had been crying when she came forth again and walked away to Twenty-fourth Street. Friday came. Shorty was ten minutes late at first recitation and failed in every lesson, yet not a word of rebuke came from any one of the masters. Halsey merely inclined his dark head, and with a tinge of sympathy in his tone, wherein they had long known only cutting sarcasm or stern admonition, said, "Never mind going further to-day." At recess, again, the boy bounded away to the Lawrences' and came back five minutes late, with face as hopeless as before, but he bore a note, which he laid upon the Doctor's desk, and without a word accepted the "ten marks off" for his delay, which at any other time would have caused a storm of protest. Pop arrived three minutes ahead of time, saw at a glance that little Pythias was down near the foot of the class, and made not the faintest allusion to it. He had barely taken his seat and looked over the two or three notes when a heavy tread was heard upon the stair, and despite Halsey's efforts the recitation hung fire, and every boy stared as a tall, grim-visaged, angular man of middle age stepped within the door, and in another moment was clasping hands with the Doctor, who left his dais to greet him. There was a brief, low-toned exchange of words, then Halsey and the new-comer caught each other's eye, despite the former's effort to stick to his work, and, faintly flushing, Halsey arose, and they too shook hands.

"How have they done to-day, Mr. Halsey?" promptly queried the Doctor; and as nobody had done well or behaved ill, Halsey hesitated. He could not dissemble. Pop saw the hitch and cut the Gordian knot.

"Gentlemen of the First Latin," he said, "the school is honored by a visit from one of Columbia's most distinguished alumni. Shall we give him an exhibition performance in the Anabasis or—take half holiday?"

The class would rather stay but not exhibit; and so in five minutes the decks are clear, and, next to Beekman, the shortest boy in the highest class is being presented to the tall graduate. Before the name was mentioned he knew that it must be Lawton's step-father, Mr. Park.

First there has to be another conference of some ten minutes' duration between the Doctor and his visitor, who had taken the youngster's hand and looked down into his anxious face with solemn, speculative eyes and without the ghost of a smile. Shorty feels his soul welling up in mightier sympathy with Snipe. There is not a thing in Park's manner to invite a boy's trust or confidence. Then the two turn to Shorty, and he is summoned to rejoin them.
