IN putting these notes together, I have been animated solely by the desire to enable those, whom motives of self-interest, or of ambition, or the irresistible impulse of innate genius, may induce to enter upon the profession of blacking, to acquire by living examples of acknowledged ability, a true and genuine perfection in the art. For art it is. Let nobody undertake it lightly. There is no room in the busy throng of ardent blackers for the idler or the fribble. Such men may write books, they cannot black boots. Style is everything, style which colours the boots, roots itself in them, and uplifts them to the highest pinnacle of Art. (N.B.--I took this sentens nearly strait from GEORGE BAINTON.--_B. the B._) Therefore, my young friends, study style. Whenever you see a well-blacked boot in the street, in the counting-house, or in the sanctity of home, fix your eyes upon it. Thus you will learn, and may in time black boots as well as I do myself. (N.B.--GEORGE writes the most extronery fine English, I'm told, and o' course 'e wants the young 'uns to do the same. Same with me and the boots.--_B. the B._) My first answer is from JAMES HUGGINS, who as is well-known, polishes the foot-coverings of the innumerable visitors who throng to the Transcontinental Hotel. He says, "you ask me how I acquired my unquestioned ability as a blacker. I answer, 'by constantly studying the best models.' When I was quite a small boy I used to polish all the boots within reach, and I well remember my father humorously remonstrating with me, when he found me blacking an old pair of worsted slippers given him by my mother. There is a method of breathing on some boots and of spitting on others, which can only be acquired by long practice. A large boot with many knobs, is best for a beginner." Next I addressed my inquiries to GEORGE BREWSHER, more generally known under his nick-name of DANDY GEORDIE. No man has a wider reputation. His reply is instructive. "It is useless," he says, "to study models. I tried that, and the result was that I used to black all the patent leathers, and varnish the ordinary ones. So I gave up study and relied upon my own talents. At the present day, nobody in the whole world can put a truer shine on the dampest boot. I scarcely know how I do it. I only know I do it. I always keep my brushes in good order, drink a toothful of gin at bed-time, and never let a single day pass without blacking something." My next reply was from LEMUEL D. DODGE, of New York, a boot-polisher whose delicate and refined style has won him admirers in this country as well as his own. "Character," he observes, "is everything. I always analyse my blacking three times over, and then lay it on thin with a camel's hair-brush. I find this method much more satisfactory and less tiring than the rough and ungainly scrubbing so much in vogue with your English artists."
