The function took place in the large concert hall at the firm's Great Western Works, Small Heath, Birmingham, which was crowded by an assembly numbering several hundreds, which included the heads of departments and representatives of all grades. Mr. H. Marks, chairman of the company, presided. The presentation was made by Mr. A. T. Cocking, one of the directors, who outlined the career of the recipient. He told how Albert Williams had entered the concern at the age of eleven, in June, 1862, working under has farther at 2s. 6d. a week. At that time the firm was J. C. Onions and Co, the establishment of which was in Bradford-street, the amalgamation with the late Mr. William Allday coming about later. During the whole of Albert Williams's record he had been absent from work only four days, by reason of illness, and had never been late. He always walked to business, and did so still - a good mile and a half.
