Upon the occasion of celebrating the laying of the cornerstone of the Baltimore and Ohio Railroad in Baltimore, July 4, 1828 (a great event in the annals of the city), the exhibition of trades was a most prominent feature of the immense procession, and none made a finer display than the hatters. George Rogers commanded that division, a description of which is thus given in the Baltimore _Gazette and Daily Advertiser_ of July 5, 1828: "The hatters' car was drawn by four horses, showing the men at work in the several stages of hat-making. The group attracted much attention; they carried a banner with a white ground, and on the shield was a beaver resting on a scroll bearing the motto: 'With the industry of the beaver we support our rights,' crossed with implements of the trade, the whole supported by the motto: 'We cover all.'" Bazil Sollers commenced business in 1799 at No. 68 Market street, a location on the north side of the street, four doors east of what is now Holliday street. In 1803 he removed to No. 22 Market street, also on the north side, four doors west of Harrison street; this latter place was previously occupied by Brant & Hobby as a hat store in 1801, and by Stansbury & Hobby in 1802. Mr. Sollers continued in business on Market street until the year 1831, when he removed to North Gay, No. 15, on the northwest corner of Front street. His factory was on East, now Fayette street, three doors east of Lemon street. Mr. Sollers continued in the manufacturing business until about the year 1840. James Gould & Co. started hat-manufacturing at No. 3 Water street in the year 1802. Water street at that time was numbered from Calvert to South street, subsequently from South to Calvert, and lately renumbered as formerly. No. 3, the second building from Calvert, is now occupied by J. E. Warner & Co., commission merchants. In 1807 Joseph Cox succeeded to the business of James Gould & Co., and kept a retail store on the corner of South and Water streets. Mr. Cox had the reputation of making a superior class of hats, excelled by no manufacturer in the country, selling at both wholesale and retail. Requiring more extensive accommodations, he located his factory on the corner of Little Water and Calvert streets, where now stands the large warehouse of Keen & Hagerty, tinware manufacturers. In 1829, disposing of his hat business to Boston & Elder, he associated with himself his son James, the firm becoming "James Cox & Son, dealers in hatters' furs and wools," at No. 1 South Liberty street. In latter years, the members of this firm having acquired a competency, retired from business.
