With this latter purpose in view, he visited the extensive and celebrated organ manufactory of the Messrs. E. and G.G. Hook & Hastings, located at what was then called Roxbury, Mass., now a part of the city of Boston. These gentlemen were so pleased with his ambitious spirit, that they kindly gave him permission to visit at will their factory, and to examine into every thing connected with organ-making. After a while, this firm, discovering the ability of young Lewis as a performer, invited him, in the presence of, and at times in conjunction with, some of the most skilful organists of Boston, to test their organs before the same were offered for sale. Besides, he sometimes offered suggestions in regard to their construction before the organs were completed, some of which suggestions were adopted by the firm. It will thus be seen that our student was quite fortunate in having, in the first place, an excellent teacher, and afterwards such beneficial opportunities as those allowed him by the Messrs. Hook. No wonder, then, that with his natural abilities, his ambitious, art-loving spirit, industrious habits, and such facilities, he quite early became a proficient organist. With his acquisition of skill as a performer on the piano-forte and organ already attained, as well as with his prospects for attaining to great distinction as a player of either of them, our artist might well have been content. But with these he was not satisfied: he longed to roam over the whole field of instrumental music, to evoke and to enjoy the harmonic beauties of the many other instruments. He had, in fine, become an enthusiast in music; and yearned to become a real connoisseur, theoretically and practically.
