The reputation Mulcaster had already gained as a teacher before his appointment is shown in the fact that the post was offered to him without his application, and that he accepted it only after some hesitation, when he was promised an additional £10 of salary, on the private and personal guarantee of one of the Governors. He held the position for twenty-five years, and his successful conduct of the school is fully attested by the verdict of eminent scholars who acted as examiners, by the expressions of satisfaction in the minutes of the Council, and by the testimony of the pupils themselves, many of whom attained distinction in after-life.
Of Mulcaster’s scholars at Merchant Taylors’ School the most famous was Edmund Spenser, but in the absence of any reference to his teacher by the poet, we have to be content with the direct evidence of Lancelot Andrews, Bishop of Winchester, and Sir James Whitelock, Justice of the King’s Bench. Of the former it is recorded that he “ever loved and honoured” his former headmaster, befriending him and his son after him, and keeping his portrait over the door of his study. The latter tells us that Mulcaster besides instructing him well in Latin, Greek, and Hebrew, was careful to increase his skill in music, and chose him to act with other scholars in the plays he presented at Court, by which means the boys were taught good manners and self-confidence. The account of him in Fuller’s _Worthies_ may perhaps represent the impressions of less gifted scholars--“Atropos might be persuaded to pity, as soon as he to pardon, where he found just fault. The prayers of cockering mothers prevailed with him as much as the requests of indulgent fathers, rather increasing than mitigating his severity on their offending child.... Others have taught as much learning with fewer lashes, yet his sharpness was the better endured, because impartial, and many excellent scholars were bred under him.”
But while Mulcaster was building up securely the reputation of the school, his own position was not always comfortable, and in the end the friction between himself and the governing body became so great that he felt constrained to resign the headmastership. This was no doubt partly due to his own somewhat hasty and masterful temper, for on one occasion at least it is recorded in the minutes of the Council that he had made open apology for things said and done in anger, but there were more lasting causes of dispute. After the first eight years the promised supplement to his official income was no longer forthcoming, apparently owing to the declining circumstances of the member of the Council who had contributed it, and Mulcaster having on the strength of this extra sum increased the salary of his first assistant, conceived that he was entitled to its continuance from the Company. There were besides disputes between the Council and the authorities of St. John’s College, Oxford, where its founder, a member of the Guild, had reserved certain free places for orphans coming from the school, and in these Mulcaster was involved. While the Council seems to have acted throughout within its rights, and in the end showed a desire to deal even generously with its headmaster, it is easy to understand the difficulties of the situation, especially to a man like Mulcaster, whose natural impatience of control would not be diminished by his evident sense that in birth as well as in learning he was above his official superiors. So necessary did he feel it to regain his freedom that in 1586 he tendered his resignation, without apparently having any definite prospect of other work.
