MODEL HOUSE, This beautiful “ Baby House,” particularly desoribed in number fire of our paper, was presented to the Fair by Miss Catharine Bid dle, and was valued at $l,OOO. It was pur chased at that price and given back to Miss Biddle, who, by its re-sale and exhibition, was enabled to pay into the treasury the very handsome sum of $2,300. Another miniature house, of faultless pro portions, and furnished with exquisite taste, even including miniature gas fixtures, which were capable of being lighted, was presented by Miss Wurtz, and sold for $BOO. CUSHMAN ALBUM, This was a large and superb Album, beau tifully bound in green and gold, containing 43 exquisite sketches, contributed by as many artists of note in Boston, New York and this city. It was intended to be presented to Miss Charlotte Cushman, as a testimonial of the appreciation felt for her great liberality to the Sanitary Commission. Thirteen hundred and seventy-four dollars were raised for the com mon fund by its exhibition, of which nearly five hundred dollars came from oitizens of Boston. Dll OVI Dim CUM FAIL [Concluded.] UNION AVENUE. This Avenue, although last to be mentioned in our sketches, deserves the first praise from all who can admire that which is grand in architecture, beautiful in deooration, and com plete in appointments. Viewed from the mu sic gallery at the west end, the scene is one of rare beauty. Banners, flags and trophies meet the glance at every turn, and the rich display of oolors in the goods on the shelves and counters is almost enough to bewilder, if not weary the eye. The collection in Union Avenue alone is well worth the prioe of admis sion charged for the whole building. Nothing like it has ever been seen in this country, and never will be again for generations to come. The grand fairs of the old world sink into in significance compared with this exhibition. Everything from a horse shoe to a bride’s trousseau, or from a penny whistle to a velvet carpet can be secured without difficulty in Union Avenue, and to those about setting up housekeeping, no better plaoe oaa be found than this, where every artioie needed for oom fort or decoration is at hand without the in convenience of traveling over half the city, be fore the necessary goods are secured. The centre of the Avenue is a busy mart, where those who buy can see the articles man ufactured before their eyes. The Jacquard Loom is in operation day and night, and its delicate and intricate machinery draws crowds of spectators, with whom wonder and delight alternate as they watch the noiseless working Oub Daily Pare. of the loom, or admire the beautiful fabrio which is the result of these movements. Fancy neck ties are woven in the loom, and the suc cess of the table in a financial point of view may be judged from the fact, that on Friday last the ladies received over seventy-two dol lars as the result of the sales of these articles. American silk enters largely into the materials used, and this, no doubt, is the main reason for the great success of the table. Near to this enclosure, portraits of President Lincoln and General Grant are being printed from the plates. Retribution never had a more striking illustration than is given in the presses upon which these portraits are print ed. The press was built in England for the Confederate government, and was designed to print Confederate bonds and notes. Alas, for the vanity of human expectations 1 The press was part of the cargo of the Bermuda, when she fell into the hands of our sailors while at tempting to run the blockade. The press is a very good speoimen of English workmanship, and it has found its proper position in the Fair, where a most capital likeness of “ Honest Old Abe” is thrown from it daily and hourly to the intense satisfaction of the loyal visitors to the exhibition. Towards the Eastern end of the Avenue, another specimen of printing is shown. P. S. Duval & Son have presses in operation print ing from stone the admirable view in colors of the Fair Buildings. Few visitors to the great Fair leave without taking with them one of these fine lithographs, as a valuable memento of the grandest exhibition ever witnessed in this country. So great has been the demand for these pictures, that it has been found necessary to procure additional stones for a new edition. The Bohemian Glass Blowers, who are also located in the centre walk of the Avenue, give an interesting exhibition. The glass steam engine in full operation, attraots crowds at all hours, and it has been the means of giving visitors a more comprehensive knowledge of the power of steam and the mode of using it than volumes of explanation and description. As the articles offered for sale at the tables of the Bohemians are manufactured in the pre sence of the audience, there has been full op portunity to gain information. The machines for making horse shoes are also features in Union Avenue, and at the same time they exhibit the rapid strides being made by the universal Yankee nation in the march of improvement. The two models exhibited are similar in many respects, and both do away with the old tedious process of manufac ture. A bar of iron, placed at one end of the machine, comes out at the other end horse shoes, ready for use. The models are in full working order, and a large revenue has been derived from the sale of miniature horse shoes. Passing from these, we still find enough to instruct and amuse at the various tables in this Avenue. At the Western end is the Hospital At the time of the formation of the Commit tees of the Great Central Fair, those whose chief interest for the last three years had bef n in ministering to the sick and wounded in our hospitals, desired to be represented, and a Committee on Hospitals was the result. The ladies attached to the different hospitals enter ed warmly into the plan, and a Committee was immediately formed, Mrs. Thomas P. James acting as chairman. But the numerous duties and engagements of Mrs. James in connection with the Fair, prevented her continuing in this position, and Mrs. Geo. W. Harris was chosen in her plaoe. Subsequently a commit tee of gentlemen was organized, and the joint Committee was as follows: LADIES COMMITTEE. Mrs. G. W. Harris, Chn. Mrs. T. Newbold, Miss Julia Dunlap, See. Mrs. Brady, Mrs. General Dana, Mrs. Mallory, Mrs. Admiral Lardner, Miss Dunlap, Mrs. Commodore Engle, Miss A. E. Jones, Mrs. Command’r Turner, Miss Mcllvaine. Mrs. Charles Cushman, gents’ committee. Dr. E. Dyer, Chairman. Dr. H. C. Parry, Win. F. Jenks, Sec’y. J. E.Mears, Dr. E. A. Smith, Treat. Jno. E. Brady, Dr. Wm. W. Keen, George F. Knorr. Dr. L. S. Bolles, A circular addressed to the brave soldiers of our army and to the gallant seamen of our fiavy, was issued, explaining the object of the formation of a Committee on Hospitals, and appealing to them to assist the Committee by contributions of suoh artioles as they were ac customed to make for recreation, viz: chains, rings, picture frames, &c., &o. Bight nobly did the soldiers and seamen respond to the appeal of the Committee, and soon in the vari ous hospitals of this district, at the Naval Asy lum, and in the squadrons that line our Southern coast little workshops were organ ized, and the material supplied by the Com mittee was rapidly converted into beautiful specimens of handiwork. In some instances, altogether in the navy, the soldiers and sea men contributed the material, and where they possessed no facilities for the manufacture of articles, money was freely contributed as their offering to the noble oause. Unfortunately for a more complete success of the work of the Committee, the movements in Virginia began about this time, and all soldiers who were able were sent to the front to take part in the glorious campaign under Grant. In conse quenoe of this, much unfinished work was left in the hospitals, although some soldiers insist ed upon carrying their work with them to the field and completing it, in order to contribute something to the noble charity that had min istered to their needs so freely. The Committee are especially grateful to the seamen of our navy for their many valuable contributions. Owing to the nature of their servioe, it rarely falls within the province of
