And, in a separate building-to which no form of fire is ever admitted, unless it he in the chance visit of the watchman's lantern to the premises, which, like all the other parts of the establishment, are equally and agreeably tempered by warm air, and which, unlike all the other rooms, are bright, clean, lively-looking apartments. and exhale a delicious fragrance of fresh-cut wood and cedar-shavings, are the carpenter's-shops, in which every species of wooden work requisite to the printers', binders', and booksellers' trades is prepared, among which are included neatly finished pairs of type-cases, turned out at the rate of fifty pair every week, printer's desks and all the other requisites of the printing office.

Here is also the pattern-room: where, by dint of self-acting' drills, saws, planes, and the like, wooden patterns are manufactured from the neat and accurate designs of the drafting-rooms, of every portion of the machinery used, in accordance to and close imitation of which the castings, forgings, and finishing of all the work is accomplished to perfection.

With this department, the survey of the Broome street manufactories and saw-works is terminated. The Gold street establishment is principally applied to the storing and exhibition of all the various articles earning under the head of letter-press, compositors', warehouse, welting, and bookbinders'.tools departments- and here is kept ready, at a moment's notice, a large assortment of hand-presses, copying-presses, ruling, cutting, and piercing machines, in great variety and equal excellence, of all prices. In this building, moreover, are manufactured the beautiful and excellent vertical steam-engines from five horsepower, 6 inch cylinders, and 10 inch stroke, up to fifteen horse-power, 11 inch cylinders, and 22 inch stroke, the largest of which are in use in the Herald, Tribune, and Sun offices, for putting in motion the large fast printing machines, by which those largely circulated Journals are thrown ofr daily in huge editions with unparalleled rapidity.

Here also are built the portable steam-engines from 3 to 4 horse-power, with vertical tubular boilers; and the hydrostatic presses, for the finishing of printed sheets, which have come into so general and wide a field of operation within the last few years. The following is a correct and beautifully finished representation of the great fast printing eight-cylinder machine in the vault of the Sun office in full operation; without which the end and object of this paper would be incomplete.

This immense printing machine is 33 feet long, 14 feet 8 inches high, and 6 feet wide. It has one large central cylinder, on which the type is secured, and eight smaller cylinders arranged around it, at convenient distances. Eight persons supply the eight small cylinders with the sheets, and at each revolution of the large cylinder eight impressions are given off, the sheets being delivered in neat order by the machine itself. The limit to the speed is in the ability of the eight persons to supply the sheets. At the rate of 2,500 sheets to each, the press would give off the unparalleled number of 20,000 printed impressions per hour. The press is used exclusively for newspapers, or similar printing. The principles and operation of this wonderful invention are thus conclusively and laconically described in Messrs. Hoes catalogue mentioned above, which we annex, without alteration, for reasons heretofore assigned, and to which we can add nothing beyond the expression of our sincere and earnest admiration.

" A horizontal cylinder of about four and a half feet in diameter, is mounted on a shaft, with appropriate bearings; about one-fourth of the circumference of this cylinder constitutes the bed of the press, which is adapted to receive the form of types-the remainder is used as a cylindrical distributing table. The diameter of the cylinder is less than that of the form of types, in order that the distributing portion of it may pass the impression cylinders without touching. The ink is contained in a fountain placed beneath the large cylinder, from which it is taken by a ducter roller, and transferred by a vibrating, distributing roller to the cylindrical distributing table; the fountain roller receives a slow and continuous rotary motion, to carry up the ink from the fountain. " The large cylinder being put in motion, the form of types thereon, is-in succession-carried to four or more corresponding, horizontal, impression cylinders arranged at proper distances around it, to give the impression to four or more sheets, introduced one by each impression cylinder.

The fly and feed boards of two of the impression cylinders are similar to those on the well-known double cylinder press; on the other two, the sheet is fed in below and thrown out above. The sheets are taken directly from the feed-board, by iron fingers attached to each impression cylinder. Between each two of the impression cylinders there are two inking rollers, which vibrate on the distributing surface while taking a supply of in I", and-at the proper time-are caused to rise by a cam, so as to pass over the form, when they again fall to the distributing surface. Each page is locked up upon a detached segment of the large cylinder, called by the compositors a "turtle," and this constitutes the bed and chase. The column rules run parallel with the shafts of the cylinder, and are consequently straight, while the head, advertising, and dash rules, are in the form of segments of a circle. A cross section of the column rules would present the form of a wedge, with the small end pointing to the centre of the cylinder, so as to bind the types near the top; for the types being parallel, instead of radiating from the centre, it is obvious that if the column rules were also parallel, they must stand apart at the top, no matter how tight they were pressed together at the base; but with these wedge shaped column rules, 'which are held down to the bed or " turtle, " by tongues, projecting at intervals along their length, and sliding in rebated grooves cut crosswise in the face of the bed, the space in the grooves between the column rules, being filled with sliding blocks of metal, accurately fitted, the outer surface level with the surface of the bed, the ends next the column rules being cut away underneath to receive a projection on the sides of the tongues, and screws at the end and side of each page to lock them together, the types are as secure on this cylinder as they can be on the old flat bed.

The cut represents a press with eight impression cylinders, capable of printing from 16,000 to 20,000 impressions per hour. Eight persons are required to feed in the sheets, which are thrown out and laid in heaps by self-acting flyers, as in our ordinary cylinder presses. " Two of these presses, of completest power and finish, have, we understand, been ordered for the printing of the Public Ledger of Philadelphia, a penny paper of the widest circulation, and of as efficient usefulness as any journal in the United States. For the past three years the Messrs. Hoe & Co. have maintained, at their own expense, an evening school for the instruction of their apprentices and employees, in Mathematics, the Exact Scienccs, Mechanical Drawing, the French and English Languages, etc. Everyone of their man & apprentices is required to give a punctual attendance at the school, which is also open to such adult members of the establishment as choose to attend. Two teachers, Messrs. O'Gorman and Dick, are regularly employed, and Prof. Hyatt has just closed the winter term with a course of lectures on Experimental Philosophy. They were attended by nearly all the workmen as well as the apprentices.

We mention these facts because we consider them worthy of being imitatcd by other large employers of laboring men. We have scarcely words in which to convey our respect and admiration for the genius, skill, enterprise, energy and perseverance by which those intelligent and able young men have attained to their present high and enviable position, and by which they have placed the American press-so far as the pcrfection of time-gaming, and labor-saving madlincry, and the altainment of facility, precision, certainty and punctuality are concerned, far ahead of that of any other country in the world.

We regret that the conductors of some of the leading journals do not cxert as beneficial a course in the employment of the highest grades of intellectual capacity in thc preparation of their leaders, and as carnest a resolution to perfect the tone of their presses, by the suppression of all scandals, libels, falsehoods, and sophistries; by the dissemination of truths, whole truths, and nothing uut truths; in the discouragement of all license and licentiousness; in the promotion and propagation of all humane charities, justice, benevolence, morality, and virtue, of art and science, literature and learning, as the Messrs. Hoe have displayed in the perfectionating the material portion of the department. Then we should have a public press equal to the requirements, moral, intellectual and physical, and worthy of the name of a people, which is ever proud to array itself in the first rank of the human race, as regards general education, intellectual capacity, and the diffusion of knowledge among all classes; and which, beyond a doubt, does actually number more readers, in proportion to the amount of its population, than any other country in the universe. To conclude: it has been said, that the greatest benefactor of the human race is he who causes two blades of grass to grow where but one grew before: but to our eyes, he seems a greater benefactor-inasmuch as the intellectual are loftier and nobler than thc physical wants of man-who causes ten-we might better say ten thousand, good and wise books -ten thousand copies of the Holy Gospel to be circulated among the people, where but one was circulated before. And, of a truth, we know none to whom thc above high praise is more justly applicable than to the inventors and owners of the Fast Printing Power- Press. Fortune and Fame attend them.
