But, tdwn I flrat contorted the architect several years ago, lead woa In oarlooa trouble. 9room* had sold tho llnlrg needed to be 1/4-Inch thick and tho architect, understandably, mb about to throw tht idea out the window. Rot that you can throw 16-lb. lead very far, bat evan tint opportunity would not hove presented Itself If mare Imowledgshle heeds had not Informed the architect that be needed only 6- or 8-lb. lead to do the lob. Incidentally, the architects for tha building are now resident* jg It, haring moved there shortly after it woa completed. Z don't mean to imply the lead lined pool and planter* were directly responsible for that but I gg mean to point out that rental apace In today's steel and glass tmaples of ecoatrce la mads more attractive through the softening effect* of reflections In water cr by landscaping. We are Increasing our efforts 1m this area and era meeting with considerable success.

Vs are presently preparing a booklet which will, we hope, go a long way to acquaint net only tha architect but the roofer as well ce proper Inrtilla- tlon methods which will take advantage of lead's properties for this purpose. Again, at course, this la a matter of education and X have every confidence that this Issue will generate at least as much interest aa our Pool* and Flantara booklet did. Rhea all it sold and done, however, tha testimonial at a aucoeaaful Installation la tha hart education of all. It eeeaa particularly fitting therefore that one of the finest Institutions of higher learning In the United States should ha la a position to provide such a testimonial.

Martin -Architectural Ssrricei - Ccnt'd ct a lead roof of sort unique type of constniction OB the Ereags Auditorls* at M.I.T. in Cambridge, Massachusetts (mentioned laat Jeer) haa niecsaafully withstood tha taat of a full year's time. 1 aa vary hapjy to report that a racant formal inspection ty Univerelty authorities, tha contractor and rapra tentative* of tha Irehitact haa ravaalad no aarloua dafaet. Sixty tona of lead aheat hart hera answered a roofing prohln which a nuxber of othar roofing materials had failad to solve. Out in Ohio, where American Electric Power Caapany la installing laad waterproofing under a landacapad roof on thalr Computer Cantor, tha problaa wi not quit# ao difficult to aolve.

This bualnaaa of *teltiplying" ties in rather neatly at thia point with one of {huce Fader's favorite atariea which, Z hope, be won't Bind Mf borrowing for a moment -- It coneerne Cod's admonition to all living eraaturaa on tha Fourth day of Creation, whan He saidt "Be fruitful and Multiply and fill the Earth." Mall, the Angel of tha Lord emetine later, in checking to see that this admonition was being followed, found all doing wonderfully -- with one exception -- a pair of aull snakes, alone, apart and unhappy. When tha Angel reported this lonely exception, the Lord slaply, and without hesitation, instructed tha Angel to ceuee a nuahar of tress to be felled and deposited asar the unhappy pair. Which tas done -- Os the next visit to Earth, tha Angel was startled to find a vary happy and extremely large faaily of little snakes had resulted. Puttied, he returned once sore to Cod and promptly informed that these little snakes were actually adders and therefore, needed only a eupply of logs to enable theai to Multiply. -- Truthfully, I feel that in the not too distant future we are going to need logs to keep track of the miltlplicity of lead-asbestoe vibration pada In use. dee of tbaee vibration attenuators has Increased at a good pace for daaplng railroad generated dis turbances. Recently, none other than the City of Mew Tork haa undertaken te use then to daap traffic born vibrations, frM heavy trucking and passenger car traffic. Vs have been given permission by the City for I.L.Z.S.O. to test this Installation in their new Public Health laboratory and, I believe, it will be i an ideal opportunity to add to our fund of usable data for engineering design. It happens that in thia aaaa building, pada are also being used under cooling tower supports on the roof, a further opportunity for on site testing. This, coupled with data frea test sites in the latest, new Grand Central area build ing, should result in information that will help the engineer to taller those already proven devices to his particular aet of circumstances. It is at this point that we will be equipped to widen the use for these pads whether for daaplng railroad vibrations or traffic disturbances or for the ayrled uses and variations possible as machinery mounts. Here la an application for lead where price is not a major factor, where longevity is essential, and where effective ness haa alreat^ bean provan empirically over a period of nany years. wnuijuinm anJjLn." -- 2--
