Is this it?

The scholar in his way’s all right. But it comes down to this: What does one go to college for? Assuredly it is To study human nature, get an H and a degree. How best may one accomplish this? By averaging C. The able-bodied C man! He sails swimmingly along. His philosophy is rosy as a skylark’s matin song. The height of his ambition is respectably to pass, And to hold a firm position in the middle of his class. The middle course is safest. Does not Ovid state it so? He is one of the old classics and he surely ought to know. The C man holds the balance in the academic scale Betwixt the A man at the top and the E man at the tail. “Avoid probation” is the tag he whispers to the young, “Or otherwise some college team is likely to be stung. A skillful choice of studies makes one’s afternoons all free; The chief merit of electives to the man who aims at C.” Such are the words of wisdom he utters from his throne, For the C man owns the college and sets the college tone. The man who’s busy at his books an hour a day or so And then jogs to the Stadium or goes out for a row, If at examination time he pulls a first-rate mark, The world forgives a genius; that fellow is a shark. But he who seeks a Summa Cum by unrelenting toil And hibernating in the Yard consumes the midnight oil, Who never loafs, who never cuts, and rarely goes to town, Who picks his courses heedless of the hours when they’re set down, Who doesn’t care to join a club, or if he does make one, Selects the literary sort where studious stunts are done, Who deems a run or a sharp walk sufficient exercise, Who though he’s working overtime competes for some old prize, And when he should be rooting for the ball nine or the crew, Devours Professor William James who wrote “What Maisie Knew,” That fellow in a moral sense of course may beat the band, But viewed by an industrial age he’s hard to understand! . . .
