It was not long before Dr. Glennie began to discover—­what instructors of youth must too often experience—­that the parent was a much more difficult subject to deal with than the child.  Though professing entire acquiescence in the representations of this gentleman, as to the propriety of leaving her son to pursue his studies without interruption, Mrs. Byron had neither sense nor self-denial enough to act up to these professions; but, in spite of the remonstrances of Dr. Glennie, and the injunctions of Lord Carlisle, continued to interfere with and thwart the progress of the boy’s education in every way that a fond, wrong-headed, and self-willed mother could devise.  In vain was it stated to her that, in all the elemental parts of learning which are requisite for a youth destined to a great public school, young Byron was much behind other youths of his age, and that, to retrieve this deficiency, the undivided application of his whole time would be necessary.  Though appearing to be sensible of the truth of these suggestions, she not the less embarrassed and obstructed the teacher in his task.  Not content with the interval between Saturday and Monday, which, contrary to Dr. Glennie’s wish, the boy generally passed at Sloane Terrace, she would frequently keep him at home a week beyond this time, and, still further to add to the distraction of such interruptions, collected around him a numerous circle of young acquaintances, without exercising, as may be supposed, much discrimination in her choice.  “How, indeed, could she?” asks Dr. Glennie—­“Mrs. Byron was a total stranger to English society and English manners; with an exterior far from prepossessing, an understanding where nature had not been more bountiful, a mind almost wholly without cultivation, and the peculiarities of northern opinions, northern habits, and northern accent, I trust I do no great prejudice to the memory of my countrywoman, if I say Mrs. Byron was not a Madame de Lambert, endowed with powers to retrieve the fortune, and form the character and manners, of a young nobleman, her son.”

The interposition of Lord Carlisle, to whose authority it was found necessary to appeal, had more than once given a check to these disturbing indulgences.  Sanctioned by such support, Dr. Glennie even ventured to oppose himself to the privilege, so often abused, of the usual visits on a Saturday; and the scenes which he had to encounter on each new case of refusal were such as would have wearied out the patience of any less zealous and conscientious schoolmaster.  Mrs. Byron, whose paroxysms of passion were not, like those of her son, “silent rages,” would, on all these occasions, break out into such audible fits of temper as it was impossible to keep from reaching the ears of the scholars and the servants; and Dr. Glennie had, one day, the pain of overhearing a school-fellow of his noble pupil say to him, “Byron, your mother is a fool;” to which the other answered gloomily, “I know it.”  In consequence of all this violence and impracticability of temper, Lord Carlisle at length ceased to have any intercourse with the mother of his ward; and on a further application from the instructor, for the exertion of his influence, said, “I can have nothing more to do with Mrs. Byron,—­you must now manage her as you can.”
