which he knew would be most dangerous to him, and he dreaded it accordingly.
It was a raw spring morning when his turn came to go up. His father and Kate drove round with him to the University gates.
"Keep up your pluck, Tom," the old gentleman said. "Be cool, and have all your wits about you. Don't lose your head, whatever you do."
"I seem to have forgotten the little I ever knew," Tom said dolefully, as he trudged up the steps. As he looked back he saw Kate wave her hand to him cheerily, and it gave him fresh heart.
"We shall hope to see you at lunch time," his father shouted after him. "Mind you bring us good news." As he spoke the carriage rattled away down the Bridges, and Tom joined the knot of expectant students who were waiting at the door of the great hall.
A melancholy group they were, sallow-faced, long-visaged and dolorous, partly from the effects of a long course of study and partly from their present trepidation. It was painful to observe their attempts to appear confident and unconcerned as they glanced round the heavens, as if to observe the state of the weather, or examined with well-feigned archaeological fervour the inscriptions upon the old University walls. Most painful of all was it, when some one, plucking up courage, would venture upon a tiny joke, at which the whole company would gibber in an ostentatious way, as though to show that even in this dire pass the appreciation of humour still remained with them. At times, when any of their number alluded to the examination or detailed the questions which had been propounded to Brown or Baker the day before, the mask of unconcern would be dropped, and the whole assembly would glare eagerly and silently at the speaker. Generally on such occasions matters are made infinitely worse by some Job's comforter, who creeps about suggesting abstruse questions, and hinting that they represent some examiner's particular hobby. Such a one came to Dimsdale's elbow, and quenched the last ray of hope which lingered in the young man's bosom.
"What do you know about cacodyl?" was his impressive question.
"Cacodyl?" Tom cried aghast. "It's some sort of antediluvian reptile, isn't it?"
The questioner broke into a sickly smile. "No," he said. "It's an organic explosive chemical compound. You're sure to be asked about cacodyl. Tester's dead on it. He asks every one how it is prepared."
Tom, much perturbed at these tidings, was feverishly endeavouring to extract some little information from his companion concerning the compound, when a bell rang abruptly inside the room and a janitor with a red face and a blue slip of paper appeared at the door.
"Dillon, Dimsdale, Douglas," this functionary shouted in a very pompous voice, and three unhappy young men filed through the half-opened door into the solemn hall beyond.
The scene inside was not calculated to put them at their ease. Three tables, half a dozen yards from each other, were littered with various specimens and scientific instruments, and behind each sat two elderly gentlemen, stern-faced and critical. At one side were stuffed specimens of various small beasts, numerous skeletons and skulls, large jars containing fish and reptiles preserved in spirits of wine, jawbones with great teeth which grinned savagely at the unfortunate candidate, and numerous other zoological relics. The second table was heaped over with a blaze of gorgeous orchids and tropical plants, which looked strangely out of place in the great bleak room. A row of microscopes bristled along the edge. The third was the most appalling of all, for it was bare with the exception of several sheets of paper and a pencil. Chemistry was the most dangerous of the many traps set to ensnare the unwary student.
"Dillon—botany; Dimsdale—zoology; Douglas—chemistry," the janitor shouted once more, and the candidates moved in front of the respective tables. Tom found himself facing a great spider crab, which appeared to be regarding him with a most malignant expression upon its crustacean features. Behind the crab sat a little professor, whose projecting eyes and crooked arms gave him such a resemblance to the creature in front that the student could not help smiling.
"Sir," said a tall, clean-shaven man at the other end of the table, "be serious. This is no time for levity."
Tom's expression after that would have made the fortune of a mute.
"What is this?" asked the little professor, handing a small round object to the candidate.
"It is an echinus—a sea-urchin," Tom said triumphantly.
"Have they any circulation?" asked the other examiner.
"A water vascular system."
"Describe it."
Tom started off fluently, but it was no part of the policy of the examiners to allow him to waste the fifteen minutes allotted them in expatiating upon what he knew well. They interrupted him after a few sentences.
"How does this creature walk?" asked the crab-like one.
"By means of long tubes which it projects at pleasure."
"How do the tubes enable the creature to walk?"
"They have suckers on them."
"What are the suckers like?"
"They are round hollow discs."
"Are you sure they are round?" asked the other sharply.
"Yes," said Tom stoutly, though his ideas on the subject were rather vague."
"And how does this sucker act?" asked the taller examiner.
Tom began to feel that these two men were exhibiting a very unseemly curiosity. There seemed to be no satiating their desire for information. "It creates a vacuum," he cried desperately.
"How does it create a vacuum?"
"By the contraction of a muscular pimple in the centre," said Tom, in a moment of inspiration.
"And what makes this pimple contract?"
Tom lost his head, and was about to say "electricity," when he happily checked himself and substituted "muscular action."
"Very good," said the examiners, and the student breathed again. The taller one returned to the charge, however, with, "And this muscle—is it composed of striped fibres or non-striped?"
"Non-striped," shrieked Tom at a venture, and both examiners rubbed their hands and murmured, "Very good, indeed!" at which Tom's hair began to lie a little flatter, and he ceased to feel as if he were in a Turkish bath.
"How many teeth has a rabbit?" the tall man asked suddenly.
"I don't know," the student answered with candour.
The two looked triumphantly at one another.
"He doesn't know!" cried the goggle-eyed one decisively.
"I should recommend you to count them the next time you have one for dinner," the other remarked. As this was evidently meant for a joke, Tom had the tact to laugh, and a very gruesome and awe-inspiring laugh it was too.
Then the candidate was badgered about the pterodactyl, and concerning the difference in anatomy between a bat and a bird, and about the lamprey, and the cartilaginous fishes, and the amphioxus. All these questions he answered more or less to the satisfaction of the examiners—generally less. When at last the little bell
