More than 2.000 gallons of red lead paint is being used. When it is completed every window in all of the buildings will have the added protection of a new coat of red lead paint. Two years ago red lead paint was applied to the steel sills of the win dows throughout the buildings and now these members are receiving an additional coat of red lead along with the sash. Thus an extra thick protec tion of highly weather resistant paint is being built up on the metallic sur faces subject to the most severe ex posures of sun and rain. One of the most attractive features about Parkchester is the clean, well kept appearance and the feeling it has of permanence. This together with its great size and the high quality of materials used in its maintenance will insure its stability as an attractive residence community for many years to come.

This group of five buildings contains 54 duplex type apartments of 4l/o rooms each with bedrooms on the second floor. It is of brick veneer construction with slated asphalt shin gle roofs. All flashings are of 2V2-lb. lead alloy sheet, including valleys, base and cap flashings at walls and chimneys and porch roof flashings. Lead flashings, where in contact with masonry, are painted with heavy as phalt paint. The owner. Old Colony Gardens Inc., of Stamford, Conn., need have no fear that rust or corrosion will damage or destroy this material. The resistance of lead to these forces is well known and has been demon strated through centuries of exposure. They are likewise sure that they will not be bothered with troublesome staining of woodwork or masonry. Mayflower Gardens project was de signed by W. J. Provoost, architect of Stamford, Conn.

After the seal is made, two perfora tions are made in the lead strip and two tiny tubes are inserted. Through one tube dried air is forced into the space while a vacuum on the other tube draws out any dampness that may have been enclosed. The tubes are then withdrawn and the holes are sealed with solder. No attempt is made to create a vacuum since glass is sufficiently elastic to be distorted by a difference in air pressure. Lead alloy is particularly adapted to this use because its softness and freedom from elasticity tend to com pensate for the hardness of the glass and to eliminate stresses which might result from inside and outside tern- Sample squares of Thermopane.

The amendment requires that the reducing bend shall be so formed that the reduction in diameter shall not produce any obstruction to flow through the pipe.

There is a remarkable similarity between the elaborate cornices, the shaped modillions being almost iden tical in scale and spacing. The Gibbs house lacks the dentil course which adds refinement to the Means house. The broken architrave over the second story windows of the Means house is recalled by the break front cornices over the windows of the Gibbs house. The similarity of detail on these two widely separated houses is with out doubt a coincidence. However it is not a coincidence that they are both painted with pure white lead paint. North or south, in cold climate or hot, there is no better paint than the pure white lead with which these houses and many other American landmarks have been painted and preserved for our enjoyment. Modern painters take pride in carrying on the tradition of their predecessors who used pure white lead paint so effectively to pro tect the historical structures of our country. * DAYTON SYNDEt THIS IS NO. 16 OF A SF.RIES REPRESENTATIVE OF THE MANY AMERICAN LANDMARKS IN VARIOUS SECTIONS OF THE COUNTRY THAT ARE PRESERVED FOR THE FUTURE WITH PURE WHITE LEAD AND OIL PAINT.
