Improved Gas Burners

Ia the American Gas Light Journal for Maren 2nd, 188B, tbere appears a paper which was read before the American Gag Light Association at its recent meeting, on the use oí the Siemens-Lungren Gs Burner, and its econoray in the consumption of gas. Thia is the burner recently ïntroduced by the Ann Arbor Gas Light Co. in several of our business house; and in the new M. C. R. R. depot, and which is now attracting much aitention. The article gives the result of the use of tLe burner in several stores where it was used. The burners ued consume but 12 feet of gas per hour, and this is guaranteed by the manufactureros. Two burners displaced eleven Iarge oil lampa, at an expense of $2.48 each per month for May, June, July and August and since their adoption last April up to February lst, 1887, with gas at $2.25 per 1000 teet they have cost $31.76. No single month shows an excess of $4.50,, with an average cost„ of $3.17 per month for the ten months, The article says . "I tind upon careful calculation acd almost eleven month's experience that two 12 feet Lungren burners light the same internat area equally as well as would be done by a full are electric light with the positive advantage of two points of distribution, a light that is white, perfectly steady and under ones own control. They cannot pass or consume more gas than claimt !, so the expense may be calculated to a nicety. A comparison with a charge of say 40 cents per night for an are light and gas at or about $2.00 per 1000 feet shows that two Lungren's will burn one year for one half the expense of the are and light the same space. Mr. Lungren the inventor of the lamp was a gradúate of the University in the classof 1875.
