Farnsworth, who rode about in a coupé to save his breath for business and contention, drove up in front of Meadows's shop one morning at half-past nine, and made his way back among chandeliers of many patterns in incongruous juxtaposition, punctuated with wall burners and table argands. In the private office at the back he found Meadows opening his letters.
The consumer's immediate remedy in any case is to use a smaller tip with the fishtail and batwing burners, and a taller chimney with the argand; which devices will give a quicker movement to the gas in one case and to the air in the other. The smoking, however, may be caused by carbonic acid, which checks combustion.
The atmospheric burners can be made from the requisite number of pieces of 1-1/4-inch gas tube 3-1/2 feet in length, one end of each being stopped, and having 1/3-inch holes drilled therein at intervals of about 1 inch, the other end being left open for the insertion of ordinary 3/8-inch brass gas taps.
Those of you who wish to study this matter further will, I think, find sufficient information in my paper on "The Construction of High-Power Burners for Heating by Gas," printed in the Transactions of the Gas Institute for 1883, and in the papers on the "Use and Construction of the Blowpipe" and "The Use of Gas as a Workshop Tool."
The hum of many voices issues from that splendid gin-shop which forms the commencement of the two streets opposite; and the gay building with the fantastically ornamented parapet, the illuminated clock, the plate-glass windows surrounded by stucco rosettes, and its profusion of gas-lights in richly-gilt burners, is perfectly dazzling when contrasted with the darkness and dirt we have just left.
Over Edwin's head the gas jet flamed through one of Darius's special private burners, lighting the page of a little book, one of Cassell's "National Library," a new series of sixpenny reprints which had considerably excited the book-selling and the book-reading worlds, but which Darius had apparently quite ignored, though confronted in his house and in his shop by multitudinous examples of it.
For these a long and narrow flame is necessary, and I may mention that in cases where a high speed of delivery is required, and a small part only has to be heated, such as, for instance, in the hardening of the points of spindles for cotton machinery, I have made burners giving a flame of exceedingly high temperature only 1/4 inch wide and five feet long.
"You will observe that this checking of the current is attained in various ways in different burners," continued the chemist as he unscrewed and dissected the samples before him. "In some it is done by a perforated metal disk in the orifice; in others, by a bit of wool, which checks slightly a slow current, and by the pressure of a strong one becomes compacted and forms a more effective obstacle.
It appeared to have been fitted up as a chemical laboratory. A double line of glass-stoppered bottles was drawn up upon the wall opposite the door, and the table was littered over with Bunsen burners, test-tubes, and retorts. In the corners stood carboys of acid in wicker baskets.
Then between those cordons of burners, extending as far as the eye could reach, the bridges stretched bars of lights, ever slighter and slighter, each formed of a train of spangles, grouped together and seemingly hanging in mid-air.
