In the earliest days of straw hat making in Baltimore, at the time when the Mackinaw was being introduced, the sewing of straw hats by machine was a new invention, and practically a close monopoly controlled by a strong combination of wealthy straw goods manufacturers of the North, who, jointly as a stock company, prevented the sale of the straw sewing machines outside their own circle. Fortunately for the success of the new undertaking in Baltimore, the good qualities of the Mackinaw hat were more satisfactorily retained by hand sewing, rendering machines in their manufacture a useless requirement. Thus an advantage was gained in supplying a hand-sewed hat, embodying such points of perfection in style and finish as to quite surprise those not familiar with the manufacture of such goods. The "Mackinaw" of Baltimore make continued to grow in popular favor until it had secured a greater distribution than was ever before attained by any other article of straw hat, making a remarkable record for tenacity, by holding for upwards of fifteen successive years, popularity as the leading article of summer headwear. Baltimore continued to enlarge and increase her straw hat factories and improve their products, so that now in this industry she stands in the proud position of being the leading city in the United States in the production of the best class of straw hats. This, in brief, is a history of another branch of the hat business, which attained large proportions, supplementing the one which, having gained a degree of importance in the manufacturing history of the city, was by force of circumstances reduced to comparative insignificance. The growth of the straw hat business of Baltimore may be looked upon as somewhat phenomenal. The first introduction of the Mackinaw hat by William R. Cole & Co., in 1867, may be taken as the beginning of straw goods manufacturing, and with but a single manufacturing firm existing in 1875, its development and increase dates from that time. It is doubtful if in 1875 the total value of manufactured straw goods produced in Baltimore reached the sum of $75,000, while in the face of a steady and constant decline in values--the result of labor-saving machines, together with reduced cost of raw material--an increase in production of twenty-fold is an accomplishment of less than fifteen years. This success cannot be attributed to any local advantages, but is due entirely to the energy, enterprise and business qualifications of those engaged in the business, qualifications which have accomplished the result of giving valuable assistance in the city's advancement as an important manufacturing centre. It has also, by the recognized merits of its products, lent a worthy influence throughout the whole United States in sustaining the excellent reputation long enjoyed by Baltimore for the good quality and reliability of its manufactured goods.
