Well done CAT. Over to you...
Here's a brief history of the mill which will explain my clues. The seasonal clue was of course TURKEY mill. the mill is just through the bridge. Many of the original buildings appear to have survived. Now a busy industrial estate.
Turkey Mill and Whatman's Paper.
Whatman's invention of wove paper without lines running through the structure. J Whatman's wove paper was stronger than laid paper as it was thicker throughout the entire sheet. Visible laid lines are areas where there is less paper material; the lighter areas are where the paper is thinner than the darker areas. In addition it was soaked in a gluey gelatin bath of cooked up hoofs and bones which made it extremely strong and less absorbent. The strength of this type of paper and the strong gelatine sizing allowed paint to move easily over its surface and multiple layers could be applied and then wiped, scratched, or scraped away without damaging the surface of the paper. These complicated subtractive techniques were brought to the highest level of virtuosity by J M W Turner who worked regularly on Whatman paper. In 1739 war broke out between France and Spain which stopped the importing of fine notepaper from the continent. The war ended in 1748 but by then English papermakers had secured the market. At the time of Whatman’s death in 1759, J Whatman had become the largest paper producer in the country. Unusually, James Whatman's widow, Ann, continued to run the mill until their son, also called James, reached 21. Like his father he too was associated with many important developments in the field of papermaking; the use of blue smalts (a ground blue potassium glass containing cobalt) to improve the brightness of white paper and the use of chlorine to bleach coloured rags. James Whatman (the Younger) also introduced the use of metal 'Hollander' beaters to reduce the high power consumption synonymous with the crucial stage of fibre treatment in beaters. Under his leadership, Turkey Mill’s importance continued to grow until the name of Whatman was respected around the world. As early as the 1760’s when wove paper was not yet widely available to artists, Thomas Gainsborough was anxious to use it for his watercolours. In 1767 he wrote to bookseller James Dodsley in hope of obtaining some “it being what I have long been in search of for making wash’d Drawings upon … There is so little impression of the wires, and those so very fine, that the surface is like vellum” Later Gainsborough wrote, “I beg you to accept my sincerest thanks for the favour you have done me concerning the paper for drawings. I had set my heart upon getting some of it, as it is so completely what I have long been in search of... upon my honour I would give a guinea a quire for a dozen quires of it”. Whatman paper was used by JMW Turner, John Robert Cozens, John Sell Cotman and Cornelius Varley. William Blake used it for four of his illuminated books, the public being informed that they were printed on “the most beautiful wove paper that could be procured”. Many of the watercolour masterpieces in the early nineteenth century are on paper bearing the “J. Whatman” or “J. Whatman/Turkey Mill” watermarks. Throughout history Heads of State and world leaders have shown a particular penchant for Whatman paper. Napoleon used Whatman paper for writing his will; George Washington signed many state documents on Whatman paper and Queen Victoria chose Whatman for her personal correspondence. In the 1930’s Soviet leaders used Whatman paper to publish their five year plan for the future of the USSR, while the peace treaty with Japan was signed on Whatman paper at the close of World War II.
