New York FUNK & WAGNALLS COMPANY Tondon PUBLIC OPINION New York combined with The LITERARY DIGEST ol. 78, No. 1. Whole No. 1733 July 7, 1923 Price 10 Cents HE PROGRESS of heating science up to the time when the American Radiator Company was formed is pretty well summarized by this old song quoted above. Homes were either too hot or too cold; and no matter what you did to the damper the smoke went up the chimney, carrying most of the heat along. One of the first steps taken by the American Radiator Company was the establishment of a department for determining definite performance standards for its boilers and radiators. That department developed into the Institute of Thermal Research, the largest laboratories in the world devoted exclusively to problems of better warmth. Here materials are tested and every new type of boiler and radiator must prove in advance pre cisely what it can do. Architects have long been familiar with the service of the Institute of Thermal Research. It is one large reason why they so often write "AMERICAN Radiators" and "IDEAL Boilers" into their specifications. Dealing as they do with life's most sacred investment, they like to insist upon materials from which scientific tests have eliminated every element of chance. The little book, "Better Warmth and Better Health," published by this company, contains ten definite suggestions for saving coal, and other information of value to every home owner. May we send you a copy? A card to either address below will bring it to you at once.
