The senior partner of the firm, Mr. Wm. G. Boardman, attends to the sales, and gives his attention to the financial department of the business. Thus, the proprietors reap the benefit of a division of labor in their work, and each is enabled to devote his entire time and energies to his own duties. Their great success is a proof of their industry and honorable devotion to their calling. They are gentlemen in every sense of the word, esteemed by all who know them, and honored and trusted by all who have business connections with them. They liberally compensate the workmen in their employ, and act on the principle that the "laborer is worthy of his hire." Their workmen never wait for the return due their labor. Their compensation is always ready, with open hand. The business of the proprietors has increased very rapidly for the last few years, and, although they are constantly enlarging and improving their works, they find themselves unable to satisfy the increasing demand for their piano-fortes. Their establishment is situated at the corner of State and Pearl Streets, Albany, N. Y., well known as the "_Old Elm-Tree Corner_." Their store is always open to the public, and constantly thronged with customers and visitors, who meet with attention and courtesy from the proprietors and persons in attendance. We would advise our readers, should business or pleasure lead them to the capital of the Empire State, to call on Messrs. Boardman & Gray at their ware-rooms, even though they should not wish to purchase anything from them; for they may spend an hour very pleasantly in examining and listening to their beautiful and fine-toned piano-fortes with the Dolce Campana Attachment. INSTRUCTIONS. Have your piano-forte tuned, at least four times in the year, by an experienced tuner; if you neglect it too long without tuning, it usually becomes flat, and troubles a tuner to get it to stay at concert pitch, especially in the country. Never place the instrument against an outside wall, or in a cold, damp room. Close the instrument immediately after your practice; by leaving it open, dust fixes on the sound-board and corrodes the movements, and, if in a damp room, the strings soon rust. Should the piano-forte stand near or opposite a window, guard, if possible, against its being opened, especially on a wet or damp day; and, when the sun is on the window, draw the blind down. Avoid putting metallic or other articles on or in the piano-forte; such things frequently cause unpleasant vibrations, and sometimes injure the instrument. The more equal the temperature of the room, the better the piano will stand in tune. * * * * * DEVELOPMENT OF THE LUNGS.
