After Mr. Barry’s appointment as architect, he still received the same aid in preparing detailed drawings for the estimate, most of which however, by changes in design, were afterwards set aside. Finally, at his recommendation, Mr. Pugin was formally appointed superintendent of the wood carving, and in that capacity he directed, first the formation of a valuable collection of plaster casts of the most famous examples at home and abroad, and next the execution of the wood-work, ornamental metal-work, stained glass, and encaustic tiles throughout the whole building. But in all cases it was thoroughly understood between them, that the architect’s supremacy was to be unimpaired. Every drawing passed under his eye in all cases for supervision, in very many for alteration. Mr. Pugin’s originality and enthusiasm never interfered with this understanding: he would carry out vigorously and heartily what he himself could not altogether approve.[83] His suggestions and criticisms, freely given and freely received, were invaluable; and his enthusiasm, even in its eccentricities, was inspiring and irresistible. For more than five and twenty years the intercourse between the two friends and coadjutors continued, unbroken by any differences except in taste, and, when Mr. Pugin was struck down by his fatal illness, Mr. Barry felt that his loss was irreparable. In the stone-carving Mr. Barry was fortunate in securing aid, only less valuable than that of Mr. Pugin. In the same work, at Birmingham, he discovered Mr. Thomas, then working as an ordinary stone-carver on the building. He was struck by his ability, skill, and energy, and at once resolved to aid in raising him to a position more worthy of his talents. After experience of his powers, he entrusted to him, under the same supervision, the entire direction of the stone-carving throughout the building. The result proved the wisdom of the choice. Under Mr. Thomas’s direction, stone-carving made a great step, which was felt in its effect upon architectural sculpture throughout the country, and which has conduced powerfully to the remarkable progress which it has since made up to the present time. With the general results of his exertions Mr. Barry was fully satisfied, and rejoiced greatly when his success in this capacity enabled him to take and to support elsewhere an independent position.
