their interests extending across state boundaries and felt in many areas.
    The two brothers specialized in the manufacture of hard rubber products. They began the manufacture of fountain pens, being among the first in the country to take up that industry. At first, they made pens for various inventors. During the middle 1850's they began to make pens for L.E. Waterman; and by 1916, the firm was devoted exclusively to the manufacture of the rubber part of the Waterman Pen. It was the only plant in the country so engaged by Waterman, and the parts were shipped to New York, where the pens were assembled.
    The success of the business was due to the business success of the other brother, Austin Goodyear Day. This brother established the Kerite Insulated Wire and Cable Works in 1854 and purchased the property and set up machinery to manufacture hard rubber goods and insulated electric wires.
    Even in the establishment of the Kerite Company, there was another family influence. Austin Goodyear Day was introduced to the rubber business when his cousin took him to Northampton to see the process of manufacturing rubber goods. The cousin - Charles Goodyear, a name now internationally known for its connections with rubber manufactures - employed Austin G. Day at his factory in Woburn, Massachusetts for several years.
    Austin G. Day became interested in experimenting with new processes of rubber manufacture. He studied the methods then in use and became a leading authority on rubber processing. He started a business in New Haven and moved it to Seymour in 1854, when he purchased the factory in Seymour from Bassett & Lodge. In this building he began the manufacture of Kerite for the insulation of electric cables for telegraph and other uses.
    The building burned in March, 1864 and was rebuilt. The rebuilt building was arranged to conduct the submarine telegraph works of Austin G. Day on the lower floors, and the upper floors were retained for the use of H.P. & E. Day Company, Inc.
Austin G. Day continued in his own business, and in support of his brothers' business until his death on December
28, 1889.
