Coal.—Over half-a-million tons of coal are used in Birmingham annually.
Cocoa.—The manufacture of cocoa cannot be classed among the staple trades of the town, but one of the largest establishments of the kind in the kingdom, if not in the world, is that of Messrs. Cadbury, at Bournville, where nearly 400 persons are employed. The annual consumption of cocoa in this country is estimated at 13,000,000 lbs., and the proportion manufactured by Messrs. Cadbury, who have houses in Paris, Sydney, Melbourne, Montreal, &e., may be guessed at from the fact that their works cover nearly four acres, and packing-boxes are required at the rate of 12,000 per week.
Copying Presses were invented by James Watt in, and patented in, May, 1780. His partner, Boulton, had a lot ready for the market, and sold 150 by the end of the year.
Compressed Air Power.—A hundred years ago every little brook and streamlet was utilised for producing the power required by our local mill-owners, gun-barrel rollers, &c. Then came the world's revolutioniser, steam, and no place in the universe has profited more by its introduction than this town. Gas engines are now popular, and even water engines are not unknown, while the motive power derivable from electricity is the next and greatest boon promised to us. Meanwhile, the introduction of compressed air as a means of transmitting power for long distances marks a new and important era, not only in engineering science, but in furthering the extension of hundreds of those small industries, which have made Birmingham so famous a workshop. In the Birmingham Compressed Air Power Company's Bill (passed March 12, 1884), the principle involved is the economic utility of centralising the production of power, and many engineers are of opinion that no other means can possibly be found so convenient as the use of compressed air in transmitting motive power, or at so low a cost, the saving being quite 20 per cent, compared with the use of steam for small engines. The Birmingham Bill provides for the supply of compressed air within the wards of St. Bartholomew, St. Martin, Deritend, and Bordesley, which have been selected by the promoters as affording the most promising area. In the three wards named there were rated in March of 1883, as many as 164 engines, of which the nominal horse-power varied from 1/2 to 10, fifty-nine from 11 to 20 fifteen from 21 to 30, six from 32 to 50, ten from 52 to 100, and four from 102 to 289. Assuming that of these the engines up to 30-horse power would alone be likely to use compressed air, the promoters count upon a demand in the three wards for 1,946 nominal, and perhaps 3,000 indicated horse-power. To this must be added an allowance for the probability that the existence of so cheap and convenient a power "laid on" in the streets will attract other manufacturers to the area within which it is to be available. It is proposed, therefore, to provide machinery and plant capable of delivering 5,000 indicated horse-power in compressed air, and to acquire for the works sufficient land to permit of their dimensions being doubled when extension shall become necessary. The site which has been chosen is a piece of ground belonging to the Birmingham and Warwick Canal Company, and situated by the canal, and bounded on both sides by Sampson Road North and Henley Street. Here the promoters are putting down four air-compressing engines, driven by compound and condensing steam engines and which are to be heated by six sets (four in each set) of elephant boilers. From the delivery branches of the air-compressors a main 30in. in diameter will be laid along Henley Street, and, bifurcating, will be taken through Sampson Road North and Stratford Street at a diameter of 24in. The mains will then divide, to as to pass down Sandy Lane, Fazeley Street, Floodgate Street, Bradford Street, Bromsgrove Street, and other thoroughfares, giving off smaller branches at frequent intervals, and so forming an elaborate network. The whole cost of buildings, plant, and construction is estimated at £140,500, but upon this large outlay it is hoped to realise a net annual profit of £9,164, or 6-1/2 per cent, on capital. The engineers, reckoning the annual cost of producing small steam power in Birmingham at £10 per indicated horse-power, which will probably be regarded as well within the mark, propose to furnish compressed air at £8 per annum, and if they succeed in carrying out the scheme as planned, it will without doubt be one of the greatest blessings ever conferred on the smaller class of our town's manufacturers.
Fenders and Fireirons.—The making of these finds work for 800 or 900 hands, and stove grates (a trade introduced from Sheffield about 20 years back) almost as many.
Files and Rasps are manufactured by 60 firms, whose total product, though perhaps not equal to the Sheffield output, is far from inconsiderable. Machines for cutting files and rasps were patented by Mr. Shilton, Dartmouth Street, in 1833.
Fox, Henderson and Co.—In March, 1853, this arm employed more than 3,000 hands, the average weekly consumption of iron being over 1,000 tons. Among the orders then in hand were the ironwork for our Central Railway Station, and for the terminus at Paddington, in addition to gasometers, &c., for Lima, rails, wagons and wheels for a 55-mile line in Denmark, and the removal and re-election[Transcriber's note: this is probably a typographical error for "re-erection".] of the Crystal Palace at Sydenham.-See "[Exhibitions]," "[Noteworthy men]."
Galvanised Buckets and other articles are freely made, but the galvanisers can hardly be pleasant neighbours, as at the works of one firm 40 to 50 carboys of muriatic acid and several of sulphuric acid are used every day, while at another place the weekly consumption of chemicals runs to two tons of oil of vitriol and seven tons of muriatic acid.
German Silver.—To imitate closely as possible the precious metals, by a mixture of baser ones, is not exactly a Birmingham invention, as proved by the occasional discovery of counterfeit coin of very ancient date, but to get the best possible alloy sufficiently malleable for general use has always been a local desideratum. Alloys of copper with tin, spelter or zinc were used here in 1795, and the term "German" was applied to the best of these mixtures as a Jacobinical sneer at the pretentious appellation of silver given it by its maker. After the introduction of nickel from the mines in Saxony, the words "German silver" became truthfully appropriate as applied to that metal, but so habituated have the trade and the public become to brassy mixtures that German silver must always be understood as of that class only.
Glass—The art of painting, &c. on glass was brought to great perfection by Francis Eginton, of the Soho Works, in 1784. He supplied windows for St. George's Chapel, Windsor, Salisbury and Lichfield Cathedrals, and many country churches. The east window of St. Paul's, Birmingham, and the east window of the south aisle in Aston Church, are by Eginton. One of the commissions he obtained was from the celebrated William Beckford, Lord Mayor of London, for windows at Fonthill, to the value of £12,000. He was not, however, the first local artist of the kind, for a Birmingham man is said to have painted a window in Haglev Church, in 1756-57, for Lord Lyttelton, though his name is not now known. William Raphael Eginton (son of Francis) appeared in the Directory of 1818, as a glass-painter to the Princess Charlotte, but we can find no trace of his work. Robert Henderson started in the same line about 1820, and specimens of his work may be seen in Trinity Chapel; he died in 1848. John Hardman began in Paradise Street about 1837, afterwards removing to Great Charles Street, and thence to Newhall Hill, from which place much valuable work has been issued, as the world-known name well testifies. Engraving on glass is almost as old as the introduction of glass itself. There is a beautiful specimen in the Art Gallery. Glass flowers, fruit, &c., as ornamental adjuncts to brassfoundry, must be accredited to W. C. Aitken, who first used them in 1846. American writers claim that the first pressed glass tumbler was made about 40 years back in that country, by a carpenter. We have good authority for stating that the first pressed tumbler was made in this country by Rice Harris, Birmingham, as far back as 1834. But some years earlier than this dishes had been pressed by Thomas Hawkes and Co., of Dudley, and by Bacchus and Green, of Birmingham. No doubt the earliest pressing was the old square feet to goblets, ales, jellies, &c. Primitive it was, but like Watt's first engine, it was the starting point, and Birmingham is entitled to the credit of it. It is very remarkable that none of the samples of Venetian glass show any pressing, although moulding was brought by them to great perfection. It would not be fair to omit the name of the first mould-maker who made the tumbler-mould in question. It was Mr. James Stevens, then of Camden Street, Birmingham, and it is to him, and his sons, James and William, that the world is greatly indebted for the pressing of glass. The older Stevens has been dead some years, and the sons have left the trade. Previous to this mould being made for tumblers, Mr. James Stevens made some pressed salt-moulds to order for an American gentleman visiting Birmingham. Some of the most beautiful works in glass fountains, candelabra, &c., that the world has ever seen have been made at Messrs. Oslers, Broad Street, whose show rooms are always open to visitors.
