From Louis Figuier, Les Merveilles de ^Industrie (Paris, 1873?), v°l- 2- whether it be the long web or the cylinder machine, packers may begin putting up the order. And to whom does the credit belong for this vast advance? The question is easily answered: mainly to Bryan Donkin and John Dickinson in their different lines. The first who took up the long web idea of Robert, a French workman, in principle correct but 104 in detail so imperfect that the machine of Robert & Didot, the mill owner, was an absolute failure; but Donkin's brains and skillful hands made it a perfect success. Not at once, but by long years of persever- ance, improvements and additions [he] produced the splendid perfect machine that is known now as the Fourdrinier Long Web Machine, a misnomer, it should have been a Donkin. Fourdrinier's part was like that of Boulton to Watt, capital and John Dickinson was a blacksmith making the fly- knives and bed plates for the pulp beaters. He con- ceived the idea of a wire covered cylinder inserted to, say two-thirds its diameter in a pulp vat, which by a properly arranged inside suction the pulp could be couched on an endless belt and be carried to press rolls. This idea was the foundation of the cylinder machine. His cylinder was an elaborate affair and one of very difficult construction. At the time of my visit to London he was carrying on five or six separate extensive paper mills, had the most extensive paper warehouses and was said to be the most extensive paper dealer in London. My first interview with Mr. Dickinson was not at all pleasant, for on learning that I was an American and interested in paper machinery he la
