the sign for candidates to move on to other tables, the taller man leaned over a list in front of him and marked down upon it the following hieroglyphic:—
"S. B.—."
This Tom's sharp eye at once detected, and he departed well pleased, for he knew that the "S. B." meant satis bene, and as to the minus sign after it, it mattered little to him whether he had done rather more than well or rather less. He had passed in zoology, and that was all which concerned him at present.
CHAPTER IX. — A NASTY CROPPER.
But there were pitfalls ahead. As he moved to the botany table a grey-bearded examiner waved his hand in the direction of the row of microscopes as an intimation that the student was to look through them and pronounce upon what he saw. Tom seemed to compress his whole soul into his one eye as he glared hopelessly through the tube at what appeared to him to resemble nothing so much as a sheet of ice with the marks of skates upon it.
"Come along, come along!" the examiner growled impatiently. Courtesy is conspicuous by its absence in most of the Edinburgh examinations. "You must pass on to the next one, unless you can offer an opinion."
This venerable teacher of botany, though naturally a kind-hearted man, was well known as one of the most malignant species of examiners, one of the school which considers such an ordeal in the light of a trial of strength between their pupils and themselves. In his eyes the candidate was endeavouring to pass, and his duty was to endeavour to prevent him, a result which, in a large proportion of cases, he successfully accomplished.
"Hurry on, hurry on!" he reiterated fussily.
"It's a section of a leaf," said the student.
"It's nothing of the sort," the examiner shouted exultantly. "You've made a bad mistake, sir; a very bad one, indeed. It's the spirilloe of a water plant. Move on to the next."
Tom, in much perturbation of mind, shuffled down the line and looked through the next brazen tube. "This is a preparation of stomata," he said, recognizing it from a print in his book on botany.
The professor shook his head despondingly. "You are right," he said; "pass on to the next."
The third preparation was as puzzling to the student as the first had been, and he was steeling himself to meet the inevitable when an unexpected circumstance turned the scale in his favour. It chanced that the other examiner, being somewhat less of a fossil than his confreres, and having still vitality enough to take an interest in things which were foreign to his subject, had recognized the student as being the young hero who had damaged himself in upholding the honour of his country. Being an ardent patriot himself his heart warmed towards Tom, and perceiving the imminent peril in which he stood he interfered in his behalf, and by a few leading questions got him on safer ground, and managed to keep him there until the little bell tinkled once more. The younger examiner showed remarkable tact in feeling his way, and keeping within the very limited area of the student's knowledge. He succeeded so well, however, that although his colleague shook his hoary head and intimated in other ways his poor opinion of the candidate's acquirements, he was forced to put down another "S. B." upon the paper in front of him. The student drew a long breath when he saw it, and marched across to the other table with a mixture of trepidation and confidence, like a jockey riding at the last and highest hurdle in a steeple-chase.
Alas! it is the last hurdle which often floors the rider, and Thomas too was doomed to find the final ordeal an insurmountable one. As he crossed the room some evil chance made him think of the gossip outside and of his allusion to the abstruse substance known as cacodyl. Once let a candidate's mind hit upon such an idea as this, and nothing will ever get it out of his thoughts. Tom felt his head buzz round, and he passed his hand over his forehead and through his curly yellow hair to steady himself. He felt a frenzied impulse as he sat down to inform the examiners that he knew very well what they were going to ask him, and that it was hopeless for him to attempt to answer it.
The leading professor was a ruddy-faced, benevolent old gentleman, with spectacles and a kindly manner. He made a few commonplace remarks to his colleagues with the good-natured intention of giving the confused-looking student before him time to compose himself. Then, turning blandly towards him, he said in the mildest of tones—
"Have you ever rowed in a pond?"
Tom acknowledged that he had.
"Perhaps, on those occasions," the examiner continued, "you may have chanced to touch the mud at the bottom with your oar."
Tom agreed that it was possible.
"In that case you may have observed that a large bubble, or a succession of them has risen from the bottom to the surface. Now, of what gas was that bubble composed?"
The unhappy student, with the one idea always fermenting on his brain, felt that the worst had come upon him. Without a moment's hesitation or thought he expressed his conviction that the compound was cacodyl.
Never did two men look more surprised, and never did two generally grave savants laugh more heartily than did the two examiners when they realized what the candidate had answered. Their mirth speedily brought him back to his senses. He saw with a feeling of despair that it was marsh gas which they had expected—one of the simplest and commonest of chemical combinations. Alas! it was too late now. He knew full well that nothing could save him. With poor marks in botany and zoology, such an error in chemistry was irreparable. He did what was perhaps the best thing under the circumstances. Rising from his chair he made a respectful bow to the examiners, and walked straight out of the room—to the great astonishment of the janitor, who had never before witnessed such a breach of decorum. As the student closed the door behind him he looked back and saw that the other professors had left their respective tables and were listening to an account of the incident from one of the chemists—and a roar of laughter the moment afterwards showed that they appreciated the humour of it. His fellow-students gathered round Tom outside in the hope of sharing in the joke, but he pushed them angrily aside and strode through the midst of them and down the University steps. He knew that the story would spread fast enough without his assistance. His mind was busy too in shaping a certain resolution which he had often thought over during the last few months.
The two old people and Miss Kate Harston waited long and anxiously in their sitting-room at the hotel for some news of the absentee. The doctor had, at first, attempted a lofty cynicism and general assumption of indifference, which rapidly broke down as the time went by, until at last he was wandering round the room, drumming upon the furniture with his fingers and showing every other sign of acute impatience. The window was on the first floor, and Kate had been stationed there as a sentinel to watch the passing crowd and signal the first sign of tidings.
"Can't you see him yet?" the doctor asked for the twentieth time.
"No, dear, I don't," she answered, glancing up and down the street.
"He must be out now. He should have come straight to us. Come away from the window, my dear. We must not let the young monkey see how anxious we are about him."
Kate sat down by the old man and stroked his broad brown hand with her tender white one. "Don't be uneasy, dear," she said; "it's sure to be all right."
"Yes, he is sure to pass," the doctor answered; "but—bless my soul, who's this?"
