This was true. Laura tried her utmost, with an industry born of despair. For the comforting assurance of speedy promotion, which she had given Mother, had no root in fact. These early weeks only served to reduce, bit by bit, her belief in her own knowledge. How slender this was, and of how little use to her in her new state, she did not dare to confess even to herself. Her disillusionment had begun the day after her arrival, when Dr Pughson, the Headmaster, to whom she had gone to be examined in arithmetic, flung up hands of comical dismay at her befogged attempts to solve the mysteries of long division. An upper class was taking a lesson in Euclid, and in the intervals between her mazy reckonings she had stolen glances at the master. A tiny little nose was as if squashed flat on his face, above a grotesquely expressive mouth, which displayed every one of a splendid set of teeth. He had small, short-sighted, red-rimmed eyes, and curly hair which did not stop growing at his ears, but went on curling, closely cropped, down the sides of his face. He taught at the top of his voice, thumped the blackboard with a pointer, was biting at the expense of a pupil who confused the angle BFC with the angle BFG, a moment later to volley forth a broad Irish joke which convulsed the class. He bewitched Laura; she forgot her sums in the delight of watching him; and this made her learning seem a little scantier than it actually was; for she had to wind up in a great hurry. He pounced down upon her; the class laughed anew at his playful horror; and yet again at the remark that it was evident she had never had many pennies to spend, or she would know better what to do with the figures that represented them.--In these words Laura scented a reference to Mother's small income, and grew as red as fire.
