M. SWEETSER & CO. Grav. WEST VIRGINIA LUBRICATING OIL. VOLCANO, WEST VA. As the distance from our wells at West Virginia is long and delays frequent on the Railroads, and in order to facilitate trade and accomodate customers, we have made arrangements with leading merchants in all the larger places in this country and abroad to act as agents for the sale of our product. They will keep a stock on hand and sell at our quotations, adding freight to their places of business. We shall do all we can to pro- tect and facilitate our business relations. Our friends can get the Zero, Sweetser's and Producer's brands of oil, of the various gravities, from FOSTER, WALKER & CO., 226 La Salle Street, CHICAGO. We desire to call your attention to the article of pure, natural West Virginia Oil, produced by us and sold under the above brand. This oil, when produced, contains considerable earthy matter and water in emulsion. To remove these and at the same time to make the oil of a satisfactory gravity, the oil is put into tanks and subjected to steam heat for about ten days and nights. This causes the oil to become perfectly clean, and at the same time makes it heavier through the expulsion of benzine and other detrimental volatile substances by from one to two degrees or gravity, We can recommend this oil as a perfect lubricator during the months from March to December in the more Northern latititudes, while in the Southern latititudes not subject to extreme cold, we can ALWAYS recommend it. We guaurantee it to stand a cold test of from ten to thirty degrees Fahrenheit, without becoming too thick to flow readily and always to flow more readily than lard oil, to which it is superoir as a lubricant. We claim for this oil, First—Freedom from water, grit or any impurity. Second—Lasting qualities, it being superior in this respect to Sperm and Lard Oil. Third—Not gumming or staining working parts of machinery. Information regarding prices and rates of freight, etc., cheerfully given. The following out of the railroads using our Oil have kindly permitted us to refer to them regarding the quality of the oil we supply them, viz.: The Philadelphia & Reading Railroad Co. The Boston & Maine Railroad Co. The Union Pacific Railroad Co. The Portland & Rochester Railroad Co. The Rock Island & Pacific R. R. Co. The North-Western Railway Co.
