The printing-house of the _Times_, near Blackfriars Bridge, forms a companion picture to Gutenberg's printing-room in the old abbey at Strasburg, and illustrates not only the development of the art, but the progress of the world during the intervening centuries. Visit Printing-House Square in the day-time, and you find it a quiet, sleepy place, with hardly any signs of life or movement about it, except in the advertisement office in the corner, where people are continually going out and in, and the clerks have a busy time of it, shovelling money into the till all day long. But come back in the evening, and the place will wear a very different aspect. All signs of drowsiness have disappeared, and the office is all lighted up, and instinct with bustle and activity. Messengers are rushing out and in, telegraph boys, railway porters, and "devils" of all sorts and sizes. Cabs are driving up every few minutes, and depositing reporters, hot from the gallery of the House of Commons or the House of Lords, each with his budget of short-hand notes to decipher and transcribe. Up stairs in his sanctum the editor and his deputies are busy preparing or selecting the articles and reports which are to appear in the next day's paper. In another part of the building the compositors are hard at work, picking up types, and arranging them in "stick-fulls," which being emptied out into "galleys," are firmly fixed therein by little wedges of wood, in order that "proofs" may be taken of them. The proofs pass into the hands of the various sets of readers, who compare them with the "copy" from which they were set up, and mark any errors on the margin of the slips, which then find their way back to the compositors, who correct the types according to the marks. The "galleys" are next seized by the persons charged with the "making-up" of the paper, who divide them into columns of equal length. An ordinary _Times_ newspaper, with a single inside sheet of advertisements, contains seventy-two columns, or 17,500 lines, made up of upwards of a million pieces of types, of which matter about two-fifths are often written, composed, and corrected after seven o'clock in the evening. If the advertisement sheet be double, as it frequently is, the paper will contain ninety-six columns. The types set up by the compositors are not sent to the machine. A mould is taken of them in a composition of brown paper, by means of which a "stereotype" is cast in metal, and from this the paper is printed. The advertisement sheet, single or double, as the case may be, is generally ready for the press between seven or eight o'clock at night. The rest of the paper is divided into two "forms,"--that is, columns arranged in pages and bound together by an iron frame, one for each side of the sheet. Into the first of these the person who "makes up" the paper endeavours to place all the early news, and it is ready for press usually about four o'clock. The other "form" is reserved for the leading articles,
