ABOUT LAMP CHIMNEYs.
Millions of Them Broken Every Year
 Where They Come From.

AfOc1i " OsOOO,OVO Ol 1ceLh are smashed every year in this city
 and at least 50, OO0,000 bits of glass are thrown into ash barrels, streets, alleys. gutters, sewers, etc. Yet people vent- ure out in thin-soled shoes, children in bare feet and horses without any pro- lection on their hoofs.
 Stranger still, one seldom hears of an accident arising from the presence of these bits of glass.
 The street sanitary regulations of the city fortunately do much toward obviating such accidents, and most of the broken and cracked chimneys are deposited in ash barrels and find their way to the dump, where they are gath cred up by rag-pickers and sold to junk dealers, who. in turn, sell the scraps. which are known as ''cullet, :" to the glass works at 40 cents per 100 pounds.
 The dealers in chimneys dispose ot their broken stock. which is about 5 per cent. of that carried, in the same manner.
 The breakage of lamp chimneys represents the consumption of that article. The lamp-chimney business, therefore, is of considerable impor- tance to the public.
 There are innumerable styles of lamp chimneys on the market-large, small and medium sized; long, short, round, fiat and twisted; thin, thick, narrow, broad, square, globular, seal loped, colOred, spotted, etc., from the baby chimney, 4 inches tall by 1 inch in diameter, to the great big fellow, F inches tall by 4 inches in diameter, used on the largest lamp in the market, which throws a 360-candle power light and costs from 15 cents to $2 per dozen wholesale. They even manufacture combinations of chimney and globes, while every year brings into the mar ket half a dozen or more of new styles of chimneys. Every new lamp requires a special chimney.
 Nine-tenths of the chimneys made in this country are manufactured in Pittsburgh, while most of the balance are made at Steubenville, O., while a very few are made in the natural gas regions.
 The majority of small ones are im- ported. Wherever the material in a lamp chimney is of greater cost than the labor the chimney is imported, and vice versa.
 All the shapes used in this country are of American design, but are man. ufactured abroad and brought here and sold at much less than they could be produced here. It is labor that fig ures in the cost of manufacture more than material.
 The odd shapes are all molded, while the ordinary shapes are blown and are made of lead glass and lime glass, both in this and the old country. There is feature that the casual ob- server would not notice in selecting a lamp chimney with square top. Two chimneys of almost identical appear ance are placed side by side, one of which commands a higher price. A close observation shows that tbe top and bottom of the one is rough, while the other is polished and smooth. The smooth one possesses double the durability of the rough one. The rough one is cut off and cooled, while the other is polished. Only the best quality of glass can be polished this way.
 People make great mistake in im- agining that heavy chimney is more durable than thin one. This is not the fact. The thin chimney is far more durable because of its expansion and contraction being more regular.
 The non-breakable chimney, which is made chiefly in Illinois, is non- breakable in name more so than in reality, though it is much more dura- ble than the ordinary chimney. The difference in the price however, does not warrant its purchase on the score ] of economy, hence very few are sold. The best grade of chimney is known as OA1O pOclLl OOp IllCll lS IlctllG llhS CtuY other chimney, but while hot has a | crimped ring welded to the top, while | the ordinary crimped top is merely placed in mold and shaped while hot.
 These chimneys are much less liable to break than the others, and are con- sidered we'll worth the one-third more in price. The great demand to-day is for fancy tops.
 There are also a great many chim- neys now used on gas burners. On the shelves of first-class lamp store | can be found fifty separate and distinct styles of lamp chimneys, while every i grocery in the country handles them, mostly the common grades.
 The life of lamp chimney is as uncertain as that of man. An ex- pensive one is as liable to break as soon as a cheap one, as there are many causes calculated to crack or shatter them other than a fall or contact with | another body. A draught of air, a damp chimney, a splash of water or a high blaze will any of them terminate chimney's usefulness in short order. i Cincinnati Times-Star
