A correspondent of the Eeange ist haa píiid a vis't to Printing House j Square, and passed Ihrough the various offices of the London Times, except the " Lion's den," wbich no one is penuitted to enter, or have communication with unless by writing. This is the office ot the Ëditor-in-Chief. ïhe writer wajs : At the right hand of the square is the 'office for advertisements, looking like a busy and crowded post office - the advertising of the Times is immense. Everyt.hing about the Times office is done with the utmost system and econorny - there is a place for everything, end everything is in its place. There is a perfect división of labor, and a place for each división. You enter a long room oo the first floor where the form is got ready for stereotyping ; for with the exception of a single page, left opon till the last moment for the latest intelligence, every partiële of the paper is stereotyped before it goes to prestí, A part of this room, as wel] as one of the same size above t, is used by the compositors; these are always at work, day and night, haring two sets of hands. In anotber room are two telegraphic apparatuses - one communicating with the office of Keuter, the king of lelegraphs. the other with both houses of Parliainent. What comes from Louis Napoleon or Palmerstmi's brain, is here almostas soon as it is there. The department of proof readers ia prominent and complete. Every word and point undergoes the utmost scrutiny. The stereotypiug was to me the point of cnlminating interest. To set up a single page of the Times tukes six men eight honre, and there are sixteen pages. From the moment the " form " is finished unti! it is reproduced in stereotype is exactly tvventy-five minutes. Away it is whirled to the prees, and another page quicklv follows. In i stereotyping, tissue paper is laid on the types, and over that pasteboard ; the wbole is subjbuted to heavy pressure - the impression thus obtained is inclosed n a mould, the metal is poured on it, and the work is dnne. Bisteen tous of paper is consumed each day. Frora the Times office 130,000 sheets are sent fortb daily I have not time to speak of the luxu ry of the reporters' room, of the library or the multitude of things curious and useful, that were shown to me. " And now," said I, when the gen ilemanly conductor had taken me thro' the establishment, " fan you let me see Júpiter, the head thunderer ? He an swered solemnly, " He is invisible. - He ie to be communicated with ouly by writing."
