Sombrero Key Lighthouse
A new method of treating metal had been developed in Europe known as galvanizing, where iron would be bathed in zinc. This severely retarded the corrosion of the iron. Meade found a company in Philadelphia which provided this service and submitted the plans for the lighthouse to them for an estimate of the cost. For an additional $10,000 I.P. Morris and Company agreed to galvanize the 12 inch diameter iron foundation piles of the screwpile lighthouse.
