Two years later, in 1818, Mr. Cowper invented and patented (No. 4194) his great improvements in printing. It may be mentioned that he was then himself a printer, in partnership with Mr. Applegath, his brother-in-law. His invention consisted in the perfect distribution of the ink, by giving end motion to the rollers, so as to get a distribution crossways, as well as lengthways. This principle is at the very foundation of good printing, and has been adopted in every machine since made. The very first experiment proved that the principle was right. Mr. Cowper was asked by Mr. Walter to alter Koenig's machine at The Times office, so as to obtain good distribution. He adopted two of Nicholson's single cylinders and flat formes of type. Two "drums" were placed betwixt the cylinders to ensure accuracy in the register,—over and under which the sheet was conveyed in it s progress from one cylinder to the other,—the sheet being at all times firmly held between two tapes, which bound it to the cylinders and drums. This is commonly called, in the trade, a "perfecting machine;" that is, it printed the paper on both sides simultaneously, and is still much used for "book-work," whilst single cylinder machines are often used for provincial newspapers.

After this, Mr. Cowper designed the four cylinder machine for The Times,—by means of which from 4000 to 5000 sheets could be printed from one forme in the hour. In 1823, Mr. Applegath invented an improvement in the inking apparatus, by placing the distributing rollers at an angle across the distributing table, instead of forcing them endways by other means.

Mr. Walter continued to devote the same unremitting attention to his business as before. He looked into all the details, was familiar with every department, and, on an emergency, was willing to lend a hand in any work requiring more than ordinary despatch.

Thus, it is related of him that, in the spring of 1833, shortly after his return to Parliament as Member for Berkshire, he was at The Times office one day, when an express arrived from Paris, bringing the speech of the King of the French on the opening of the Chambers. The express arrived at 10 A.M., after the day's impression of the paper had been published, and the editors and compositors had left the office. It was important that the speech should be published at once; and Mr. Walter immediately set to work upon it. He first translated the document; then, assisted by one compositor, he took his place at the type-case, and set it up. To the amazement of one of the staff, who dropped in about noon, he "found Mr. Walter, M.P. for Berks, working in his shirt-sleeves!" The speech was set and printed, and the second edition was in the City by one o'clock. Had he not "turned to" as he did, the whole expense of the express service would have been lost. And it is probable that there was not another man in the whole establishment who could have performed the double work—intellectual and physical—which he that day executed with his own head and hands.

Such an incident curiously illustrates his eminent success in life. It was simply the result of persevering diligence, which shrank from no effort and neglected no detail; as well as of prudence allied to boldness, but certainly not "of chance;" and, above all, of highminded integrity and unimpeachable honesty. It is perhaps unnecessary to add more as to the merits of Mr. Walter as a man of enterprise in business, or as a public man and a Member of Parliament. The great work of his life was the development of his journal, the history of which forms the best monument to his merits and his powers.

The progressive improvement of steam printing machinery was not affected by Mr. Walter's death, which occurred in 1847. He had given it an impulse which it never lost. In 1846 Mr. Applegath patented certain important improvements in the steam press. The general disposition of his new machine was that of a vertical cylinder 200 inches in circumference, holding on it the type and distributing surfaces, and surrounded alternately by inking rollers and pressing cylinders. Mr. Applegath estimated in his specification that in his new vertical system the machine, with eight cylinders, would print about 10,000 sheets per hour. The new printing press came into use in 1848, and completely justified the anticipations of its projector.

Applegath's machine, though successfully employed at The Times office, did not come into general use. It was, to a large extent, superseded by the invention of Richard M. Hoe, of New York. Hoe's process consisted in placing the types upon a horizontal cylinder, against which the sheets were pressed by exterior and smaller cylinders. The types were arranged in segments of a circle, each segment forming a frame that could be fixed on the cylinder. These printing machines were made with from two to ten subsidiary cylinders. The first presses sent by Messrs. Hoe & Co. to this country were for Lloyd's Weekly Newspaper, and were of the six-cylinder size. These were followed by two ten-cylinder machines, ordered by the present Mr. Walter, for The Times. Other English newspaper proprietors—both in London and the provinces—were supplied with the machines, as many as thirty-five having been imported from America between 1856 and 1862. It may be mentioned that the two ten-cylinder Hoes made for The Times were driven at the rate of thirty-two revolutions per minute, which gives a printing rate of 19,200 per hour, or about 16,000 including stoppages.

Much of the ingenuity exercised both in the Applegath and Hoe Machines was directed to the "chase," which had to hold securely upon its curved face the mass of movable type required to form a page. And now the enterprise of the proprietor of The Times again came to the front. The change effected in the art of newspaper-printing, by the process of stereotypes, is scarcely inferior to that by which the late Mr. Walter applied steam-power to the printing press, and certainly equal to that by which the rotary press superseded the reciprocatory action of the flat machine.

Stereotyping has a curious history. Many attempts were made to obtain solid printing-surfaces by transfer from similar surfaces, composed, in the first place, of movable types. The first who really succeeded was one Ged, an Edinburgh goldsmith, who, after a series of difficult experiments, arrived at a knowledge of the art of stereotyping. The first method employed was to pour liquid stucco, of the consistency of cream, over the types; and this, when solid, gave a perfect mould. Into this the molten metal was poured, and a plate was produced, accurately resembling the page of type. As long ago as 1730, Ged obtained a privilege from the University of Cambridge for printing Bibles and Prayer-books after this method. But the workmen were dead against it, as they thought it would destroy their trade. The compositors and the pressmen purposely battered the letters in the absence of their employers. In consequence of this interference Ged was ruined, and died in poverty.

The art had, however, been born, and could not be kept down. It was revived in France, in Germany, and in America. Fifty years after the discovery of Ged, Tilloch and Foulis, of Glasgow, patented a similar invention, without knowing anything of what Ged had done; and after great labour and many experiments, they produced plates, the impressions from which could not be distinguished from those taken from the types from which they were cast. Some years afterwards, Lord Stanhope, to whom the art of printing is much indebted, greatly improved the art of stereotyping, though it was still quite inapplicable to newspaper printing. The merit of this latter invention is due to the enterprise of the present proprietor of The Times.
