During the past week, the Exhibition has greatly improved in every respect. Great activity has been displayed in the opening up of new packages, and the arrangement of new articles. The average daily attendance of visitors has been about 4,000. As machinery is capable of doing almost everything now-a-days,a machine counts the number of persons who enter the building. It is an instrument like that employed at some Toll Bars to register the number of tax payers. Every person entering passes through a turn-stile which records each admission; and all that is necessary, therefore, at the end of the day to ascertain the aggregate number of visitors, is to add up the record of each turn-stile. New cases are being opened every day, and the daily visitor is greeted in each department with many novelties of which he catches glimpses onthe various counters, without, however gaining more intormation of the articles than a mere view affords him. JAPAN WORK.—The Japanese collection is now arranged, and from the many quaint articles which it displayes, attracts the attention of those curious in carvings, lans, shell, embroidery, and other ingenious trifles. This collection is small, but coming as it does from a country whose customs and native manufactures are a mystery to the traveller. It is of more interest on that account. This collection is in the German Department, aear the West entrance in the North West wing, and unless specially examined, may be overlooked by many. The articles of real Japan workmanship to which we wish to direct attention, aie some large tablets, which will bear close inspection before their merits can be fully appreciated. No such piece of Japan work has ever been seen in our country before, and it is a great curiosity The figures ar i out of proportion, and as for perspective, the Japanese do not seem to have discovered any such laws as those which regulate the operations of our artistic designers; the mechanical workmanship, however, surpasses everything that we have seen in this kind of ware. MACHIHERY.—The working machinery of the Exhibition, under the Superintendence of Joseph E. Holmes, is to be erected in a separate building at the side of the Crystal Palace. The structure is now in the course of erection, the severe hurricane, mentioned by us two weeks ago, having much delayed its advancement. It may be about three weeks before it is complete for receiving and working the machines to be exhibited. The iron work upon it is done;—The upper floor is wholly, and the lower floor nearly laid; the engines for driving the machinery are being introduced. This Department will be of the most interest to us and our readers; the delay in its erection tries our patience, but we have no doubt of eventually witnessing a display of American machinery, which will make us proud of the genius and skill ot our countrymen. Two printing presses have been introduced into the Palace, and are kept at work on the Illustrated Catalogue. We have been informed that Messrs. Hoe are not going to have one of their large lightning presses on exhibition. The reason given is, they could not get the requisite quantity ot room to erect and work it. We regret this, because we are sure that this press would command the admiration of all. It would especially arrest and rivet the attention of all our foreign brethren. Applegarth's great press was at the London Exhibition ; why should not Hoe's be at the American ? A working model of Wilkinson's new press is to be on exhibition, but that is not enough, in justice to nur omntry, we want to see the biggest and fastest press in America at the Exhibition. We also want to see some of the largest and finest locomotives, and other engines in our country, at the exhibition, for we know that we can make a show in useful machinerj equal to any nation—England not excepted— in the world, and had New York been as near to London as Paris is, there would have been a different story to tell about American machines at the World's Fair in 1851. In the Palace some excellent English cotton machinery from Manchester has been put up; it does credit to the makers, but we will be able to say more about it when it is in full operation, at present little can be said about any of the machines in the building. PUMPS, FIKK ENGINES, &C.—A very larg" centrifugal pump, ot J. Stuart Gwynne's patent, is placed in the east wing, and will astonish the on-lookers when it gets into operation ; it is intended as a fire engine if required, and it will throw a stream of great power and volume, as it is to be driven by steam. Will Aphold's be here to risk its reputation on a second trial under different auspices from that under which it was tried in competition with Gwynne's in London ? We believe it will not. Carey has also a fine rotary pump on exhibition. Both of these pumps have been illustrated in our columns; they are the best extant; those who have good machines know where to have them brought before the public for just criticism, and to spread a knowledge of theii qualities among those who are the most competent judges of their merits. An efficient Fire Brigade has been organized for the protection of the building and goods against the dangers ot fire. It will be on duty day and night. E. F. Randolf is Chief Superintendent ot the Brigade, compo'-sed, principally, of the Police. During the day the Superintendent of machinery, with his engines and centrifugal pumps, will be a powerful reserve force, enough to drown Vesuvius. A very fine engine built by William Jeffers, of Pawtucket, R. I., whose engines have been frequently noticed in our columns, has been placed at the disposal of the fire brigade. This engine can now be seen by vi-siters, and is well worthy of their attention. This engine stands in the open space, in the north nave, near the dome, and is capable of throwing water to any part of the Palace. Each section of the building is supplied with four large hydrants, with two lines of hose to each hydrant, and an extra hose tor the engine, on the lower floor. The galleries are supplied with three small hydrants, and fifty buckets of water in each of the four divisions. There are also twelve small hydrants on the lower floor. For the further and more complete protection of the edifice from fire, there will be tanks in the higher portions of the two eastern towers, capable of containing 1,-300 gallons each, which will be supplied with water by a steam force pump, from pipes connected with the main pipe on Fortieth street. These tanks connect by four inch pipes with all the lines of hose and hydrants in the main building, giving a constant head about twenty-five feet higher than the average level of the water in the Reservoir. In the machine arcade there will be one large hydrant in the centre of the building, with eight smaller ones, four on the lower floor, and four in the picture gallery; on the upper floor, each will be supplied with hose, as in the main building. Exhibitors need not place their trust in Fire Annihilators of doubtful merit, while they have such an efficient Fire Brigade. SILVER WARE—In the British Department there is already a display of silver ware which is worth travelling some distance to see. There are some cases filled with the most gorgeous specimens of table ornaments. There is a group named " The Halt in the Desert," which is a superb piece of workmanship. It is about twenty-two inches across the base, and about thirty-six inches in height, and is valued at $2,000. Upon " heavy massive ground-work stands a palm tree, about two feet three inches in height, elegantly wrought, and heavy witti flowing leaves. Around the foot of the tree are gathered three Arabs with their steeds, so grouped as to be expressive of fatigue from a weary journey. One of the horses is lying upon the ground, the others are yet standing, the rider of one is still in the saddle with lance in hand. Near this group is placed another of very exquisite workmanship, and possessing great interest for the iovers of English literature; it is named " Sir Roger De Coverly and the Gipseys." Upon a green sward, around the trunk of an old tree, despoiled of its branches, are gathered a group of six figures—Sir Roger, his companion, two gipseys, Sir Roger's horse, and a dog. Sir Roger has just alighted from his horse, which he holds by the bridle with one hand, and presents the palm of the other to one of the gipseys, who is reading his fortune, while the other gipsey, a perfect Meg Merrilies in countenance, is looking over the shoulders of her companion at De Coverly. The companion of Sir Roger stands in the back-ground, surveying the fortune tellers with apparent distrust. This work is frosted, excepting in some places in the folds ot the garments, which, being burnished, turn their silver linings to the view, and render the work beautiful and chaste. The most curious piece, however, is one named " JEsop's Tea Set." It consists of four pieces—a coffee and tea-pot, sugar bowl, and milk cup. Upon these are richly carved eight fables of iEsop in style both artistic and beau-tifn'.. We made a disWnrt csami.iation of each piece of the set, which is superior to any thing of the kind we have ever betore seen. Upon the coffee pot is wrought the two fables, "The Dog and the Shadow," and the " Wolf and the Lamb," and under the former is written the moral, " Be not over greedy," and under the latter," A tyrant never wants a plea." The figures are all raised work, presenting a beautiful picture upon the burnished surface of the piece. In connection with these illustratioas are wrought, in the same style, the coffee plant and large palm trees, indicative as to the pot, of its use, and as to the beverage, of its clime. The teapot has upon one side (it also has relief,) the fable of the " Fox and the Crane," and urder it the moral, "True charity needs no return." Upon the other side is the " Liou and the Mouse," and under it reads, " Return a favor." Upon this is carved tea plants and tropical trees. The sugar-bowl is in keeping with the pieces already described; upon it are most magnificently carved the two well-known fables ot the " Fox and the Grapes," and the " Fox and the Storks." The morals read, " Be not envious," and " Do as you would be done by," The vine hanging with clusters, and anxious Reynard seated upon a bank, consoling himself with the reflection that they are ail sour, is a triumph of the artist in this kind of work. The sugar cane grows in abundance on the surface of the bowl. The remaining piece of this magnificent set is the milk cup. This, though a small article, is nevertheless heavy with rich carving and massive figures," The Fox and the Crow," with the moral of the fable, " Learn to resist flattery," is fully pictured upon one side of this cup. The crow, sitting upon the limb of a tree, and the fox resting upon the flowery bank of a little rivulet, fully illustrate the fable. Upon the other side of this cup is the " Crow and the Pitcher," with the moral inscribed, " Science prevails over strength." The ornaments of which we have spoken compose a separate net-work, and are so neatly crossed around the pieces that all suppose them to be carved upon their surface. They are fastened firmly t, on the pieces with small screws, and at plea- sure can be taken off, leaving a plain modest tea set. The inside of each piece is plated 5 with gold. There are various other pieces, of which we shall speak in future. A correspondent in the " Tribune " advo-, cates the opening of the Crystal Palace on i Sunday. By his style and remarks he evi-j dently belongs to some of the continental cities of Europe, where the Sabbath is kept as ; a day of amusement. He asserts that the . keeping open of the Exhibition on this day , would have a tendency to elevate the thoughts and feelings of the working people, keep them I from the grog shop, and prove of general be-( nefit to them, as they cannot afford to lose . their daily labor during other days "."i the f week, for viewing such sigats. The rrmiia-j gers of the Exhibition will not pay the least y attention to such suggestions—nut solely because they are wrong in a moral sense, but because such a course wou!! receive, as it it would deserve, the sevsreet condemnation from the public. In those countries where the Sabbath is most devoted to amusement, we find the working people— those for whose benefit so many talk and write—in the most depressed condition. We hope that every exhibitor will place a label on every article he exhibits, so as to explain something about its manufacture, who made it, where it came from, what is its price, &c. This will directly benefit the exhibitors, and make the Exhibition far more interesting to visitors, and we hope the superintendents will issue and enforce an order to have this done at once.
