3 A BOND BETWEEN NATION! HE visiting French General stop- \^ ped his hostess with a gesture as she was explaining rather volubly how to use the Otis Automatic Elevator in her Park Avenue residence. Spare yourself the trouble, dear Madam. I shall need your help in finding my way about this vast city; you will have to explain to me a hundred intricacies of your American life, from the best manner of facing a large audience of your compatriots to the best manner of eating your Indian corn, but at least I am as familiar with your elevators as you yourself. Between floors I am at home, for your Otis Elevators are as indispensable to Paris as to New York, no matter how wide the difference between the two cities." Every city, every separate building presents its own problem, which has been solved, in all parts of the civilized world by the Otis Elevator Company. European cities do not have the high buildings that are constructed in this country, and therefore their elevator service is not as intensive, but Otis elevators serve the needs of their business life the same as they do in this country. The Grands Magasins du Printemps illustrated, is one of the large department stores of Paris, and contains fifteen Otis Elevators and seven Otis Escalators. Many French apartments have installations of Otis Automatic Elevators. O T I S E L E V A T O R C O M P A N Y Offices in all Principal Cities of the World

AS much as we have urged contractors to study * ** Koehring construction, few Koehring owners seem to care much about how the Koehring gets results. They seem satisfied to know that between the man on the operating platform, and the concrete on the subgrade is a responsive, smooth, speedy functioning unit that delivers a greater yardage to the subgrade than is ordinarily expected from the drum capacity! That's what means extra profits for them! Of course they know Koehring Heavy Duty Construction is "there' must be because of Koehring record of low maintenance, reliability on the job and long service life! SIZES Pavers 7-E, 13-E.27-E.
