Challis frowned heavily. He looked exceedingly uncomfortable and unhappy. He was conscious that he could take neither side in this controversy--that he was in sympathy with no one of the seven other persons who were seated in his library. He shook his head impatiently in answer to Sir Deane Elmer's question, and the chairman turned to the Rev. Philip Steven, who was gazing intently at the pattern of the carpet. "I think, Steven," said Elmer, "that your large experience will probably prompt you to a more efficient examination than we could conduct. Will you initiate the inquiry?" Steven raised his head slightly, put a readjusting hand up to his glasses, and then looked sternly at the Wonder over the top of them. Even the sixth form quailed when the head master assumed this expression, but the small child at the table was gazing out of the window. Doubtless Steven was slightly embarrassed by the detachment of the examinee, and blundered. "What is the square root of 226?" he asked--he probably intended to say 225. "15·03329--to five places," replied the Wonder. Steven started. Neither he nor any other member of the Committee was capable of checking that answer without resort to pencil and paper. "Dear me!" ejaculated Squire Standing. Elmer scratched the superabundance of his purple jowl, and looked at Challis, who thrust his hands into his pockets and stared at the ceiling. Crashaw leaned forward and clasped his hands together. He was biding his time. "Mayor" Purvis alone seemed unmoved. "What's that book he's got open in front of him?" he asked. "May I see?" interposed Challis hurriedly, and he rose from his chair, picked up the book in question, glanced at it for a moment, and then handed it to the grocer. The book was Van Vloten's Dutch text and Latin translation of Spinoza's Short Treatise. The grocer turned to the title-page. "Ad--beany--dick--ti--de--Spy--nozer," he read aloud and then: "What's it all about, Mr. Challis?" he asked. "German or something, I take it?" "In any case it has nothing to do with elementary arithmetic," replied Challis curtly, "Mr. Steven will set your mind at ease on that point." "Certainly, certainly," murmured Steven. Grocer Purvis closed the book carefully and replaced it on the desk. "What does half a stone o' loaf sugar at two-three-farthings come to?" he asked. The Wonder shook his head. He did not understand the grocer's phraseology. "What is seven times two and three quarters?" translated Challis. "19·25," answered the Wonder. "What's that in shillin's?" asked Purvis. "1·60416." "Wrong!" returned the grocer triumphantly. "Er--excuse me, Mr. Purvis," interposed Steven, "I think not. The--the--er--examinee has given the correct mathematical answer to five places of decimals--that is, so far as I can check him mentally."
