HOWELL'S RELIEF MAPS ANSTACCOURAC AND INSTANT CONCEPTION PANAMA CANAL ZONE For an intelligent and profitable study or even a working knowledge of geography, it is being rapidly realized that a good relief map is indispensable, since no printed map can illustrate the salient features of the earth with such clearness, accuracy, or completeness as do Howell's naturalistic land models. Why not, therefore, have for your office, library, or home, as well as for school, college, and university, Howell's Relief Maps, which convey to you at a glance the true outlines of the continents, brought out in bold relief, showing the boundaries and capitals of the different countries, their formation and location, colored and lettered, and, above all, absolutely accurate; and the cost of relief maps is not excessive, as supposed. Besides our great variety of relief maps, we are prepared to compile relief maps and models showing landscape gardening, municipal improvements, playgrounds, etc., in any part of the country, from data furnished. Think of the importance of being able to see every detail of your project as it will be, with proper elevations, buildings, etc., built to exact scale, as a permanent record.

Put fittings in hole; put on what you have to fasten; screw in the bolt. The fittings of soft steel have threads in lower end, but not in upper, and they draw together, expanding on all sides and both ends. The bolts will never get loose. The greater the strain, the more they hold. Catalogues and samples. F. H. EVANS, 31 to 35 Hewes St., BROOKLYN, N. Y. upon the integrity of our advertisers."
