Gentlemen:--The "Jaros Hygienic Underwear" has been in use with Conductors and Gripmen of this Company since November 1885, having been recommended by the Company's Surgeon, Dr. D. A. K. Steele. We speak for the men in asserting that this underwear is considered the best possible protection against cold and changeable temperatures, which are especially characteristic of this latitude, and its use has resulted in great protection of health and a corresponding increased efficiency. With conductors, whose occupation necessarily prevents the wearing of a very heavy overcoat, it is of great advantage, and gripmen and drivers are enabled to thoroughly protect themselves in their exposed positions without an overplus of clothing, otherwise necessary. The proper protection of men serving in Street Railway Companies is of the greatest importance; since an efficient service in trying weather is largely dependent on their prompt response. We have been pleased to secure for our employees a contract figure on the "Jaros Hygienic Underwear," and feel that the benefits fully justify us in our continuance of this arrangement. Respectively yours, C. B. HOLMES, Supt. * * * * * D. A. K. STEELE, M. D., Surgeon and Consulting Physician, Chicago City Railway Co., Ex-President Chicago Medical Society, Prof. Orthopedic Surgery, College of Physicians and Surgeons of Chicago, etc. J. JAROS, Esq., Chicago. CHICAGO, January 6, 1886. My Dear Sir:--I have critically examined and practically tested the "Jaros Hygienic Wear," and consider it the best fabric with which I am acquainted, for retaining the animal heat, and preventing chilling of the body by sudden changes of temperature. I consider the heavy wear especially valuable for car drivers, firemen, policemen, or those whose occupation expose them constantly to the inclemency of the weather. Through my suggestion to the officials of the Cable Railway Company, many of the Grip Drivers and Conductors are already using this wear with the greatest satisfaction, lessening their risk of "taking cold," and bettering their HEALTH and EFFICIENCY. Very truly yours, D. A. K. STEELE, M. D. * * * * * WEST CHICAGO STREET RAILWAY CO. CHAS. F. NAGL, Superintendent. CHICAGO, March 4, 1889. Gentlemen:--The good reports from Drivers and Conductors of our Company who are wearing the "Jaros Hygienic Underwear," satisfies us that the arrangements made for last season's delivery of the wear have been appreciated. The excellent protection under every change of temperature during the winter months, guards against attacks so frequent with men exposed, of rheumatism, kidney disease, and pulmonary troubles, and all character of ailments resulting from colds. This is too often cause for irregularities with men, which is a loss to them and often an inconvenience to the Company.
