For this good fortune he was again indebted to his friend of friends. Irving had begun to feel his position at Glasgow unsatisfactory, and at the close of 1821 he was induced to accept an appointment to the Caledonian Chapel at Hatton Garden. On migrating to London, to make a greater, if not a safer, name in the central city, and finally, be lost in its vortex, he had invited Carlyle to follow him, saying, "Scotland breeds men, but England rears them." Shortly after, introduced by Mrs. Strachey, one of his worshipping audience, to her sister Mrs. Buller, he found the latter in trouble about the education of her sons. Charles, the elder, was a youth of bright but restive intelligence, and it was desired to find some transitional training for him on his way from Harrow to Cambridge. Irving urged his being placed, in the interim, under Carlyle's charge. The proposal, with an offer of L200 a year, was accepted, and the brothers were soon duly installed in George Square, while their tutor remained in Moray Place, Edinburgh. The early stages of this relationship were eminently satisfactory; Carlyle wrote that the teaching of the Bullers was a pleasure rather than a task; they seemed to him "quite another set of boys than I have been used to, and treat me in another sort of manner than tutors are used. The eldest is one of the cleverest boys I have ever seen." There was never any jar between the teacher and the taught. Carlyle speaks with unfailing regard of the favourite pupil, whose brilliant University and Parliamentary career bore testimony to the good practical guidance he had received. His premature death at the entrance on a sphere of wider influence made a serious blank in his old master's life. [Footnote: Charles Buller became Carlyle's pupil at the age of fifteen. He died as Commissioner of the Poor in 1848 (_aet_. forty-two).]
