Charles Kohlmann, meerschaum pipe manufacturer, exhibits raw meerschaum and amber, anda fine case full of pipes and amber mouth-pieces. The State Telegraph Company exhihit an ordinary telegraphic instrument to the right hand of the fountain, where people can get “shocked” gratuitously. Similar working instrnments are exhihited by the Pacific’ Business College, and by the California Business University. Curled hair and glue are shown from the Pacific Glue Factory, of Dana & Codington. Kunitz’s Santa Cruz glue is adjacent. C. M. Chapin shows a fine case of perfumers’ and barbers’ and friseurs’ goods. Mrs. E. Doherty has a luxuriant supply of artificial hair and toupés for ladies. H. Olsen shows a combination life-preserver and swimming apparatus. The hands and feet are enlarged and webbed like a frog’s, and a bag of air is fastened on the back of the swimmer. In addition to these there remain to he mentioned: Specimens of galvanism, by G. Kustel; a model of a flying machine, in a dilapidated state, and not exhibited, by Fearing; a self-generating gas machine, by Robert Heuston; soda fountains, by Willis and others; several very interesting cabinets of stuffed birds and other specimens of natural history, hy Lorquin; a gymnastic swing, hy S.

Amongst these are a Harrison hoiler, by Tay, Brooks & Backus; an iron planing machine, hy the Pacific Iron Works; a miniature war steamer, from Woodward’s Gardens; and a fine oil painting, entitled “ Affections last Offering,” by Toby E. Rosenthal, a young San Franciscian who has been studying art for several years past with promising success, at Munich. CarvatHo’s SuPERHEATER.—This valuabls and important invention for the econonization of fuel, has been satisfactorily tested in the large hoiler which is supplying the steam for the engines at the Pavilion. Nothing could be more simple, 6r more naturalthan the increassd power from the same quantity of fuel, or from the same amount of steam when superheated. As the moist steam leaves the boiler in pipes leading to the engine and is exposed to the cold air, much of it is condensed to water and rendered ineffective. The superheater is merely a double winding of pipe filled with coils of iron wire to absorb the heat and impart it to the steam, which conducts this same steam hack again through the fire, heating it to 500°, before transmitting it, and makingit perfectly dry. The gain in effectiveness is estimated at 25 to 85per cent. The principal difficulty of the engineer at the Fair, since it is applied, has been to keep the fires low enough to avoid getting on too much pressure. The advantages of this invention are evident when if is remembered that most of the steam generated in boilers passes through a greater or less depth of water before reaching the surface, and so becomes unavoidably charged with moisture, while the water which is thus carried over hy the steam has been highly heated at the expense of the fnel, is of no henefit for power, and of little avail for heating or drying purposes. The amount of water mechanically mixed with ordinary steam is further inereased by the condensation which is constantly taking place in cylinders and steam pipes, while if the boiler ‘‘ primes,” us is quite common, the evil referred to is aggravated. The volume and elasticity of this wet steam are necessarily very greatly increased by drying it before use; and though this principle has long been known, advantage has never beeu taken of it practically on accouut of the expense aud want of durghility of the apparatus used, a difficulty which has now been successfully overcome. Being no longer a matter of experiment, the application of the superheater to all ordinary steam boilers is a mere question of economy, which can be very speedily determined by thoso who are interested. These superieaters are manufactured at the Aitna Iron Works, for Robert S. Harris, agent for the Pacific Coast. We learn from Mi John Ii €cngtable, who is the enginébr, that they are’ bei 1g adopted into vise in ‘various séctions of fhé country, Paper and Stationery. One of the most unmistakable evidences of the progress of civilization and refinementin any community, is the multiplication of hooks, paper and stationery. The hookstoreand the stationery warehouseare the local habitations of literature, and their benign influence goesout among allthe people who visit them. These two classes of husiness were formerly always connected; in fact, a **stationer” was a bookseller, so called, not because he gold books, but hecause he occupied a stand, or station, for theirsale. As the extent of this husiness increased, hy reason of the more universal interest taken in literature by the masses, the two departments were separated, and a stationer came to he considered as one who deals chiefly in paper, hlank hooks, writing materials, etc. Few persons are aware of the importance and extent of this branch of business on the Pacific Coast, or of the large amount of capital and labor employed in the home mannfacture of paper, hlank hooks, ete. It is already becoming an important branch of our industrial pursuits. Messrs. John G, Hodge & Co., at the corner of Sansoms and Sacramento streets, have long been engaged in this branch of husiness—some ten years —have the largest stationery estahlishments on the coast, and are fully prepared to meet the wants of the country at large. As people in California require the hest of everything, they pay particular attention to obtaining such goods as are manufactured by the Carew Company,—extra fine writing and ledger paper, and J. G. Shaw & Co’s make of hlank books,— both of which have a world-wide reputation, as heing superior to all others. No. 6 Dial Stamp, These goods, with everything helonging to the stationery and paper business, can he snpplied in quantities to snit, and at low prices. Messrs. Hodge & Co. are also agent for Hills’ patent dial, cancelling and bank note stamps, the only stamp in use having a dial to indicate the dates. These stamps are of various patterns, for railroads, hanks, for envelopes, seals, etc. One of the numerous neat styles is herewith illustrated, hut their superiority shows most clearly hy personal examination and long usage. This Honseis manufacturer’s agent for these stamps, and make a specialty of that branch of this trade, keeping a good variety on hand to suit the wants of the trade in regard to style, size and price. Last winter we visited Mr. Hill’s workshop in Springfield, Mass., and saw the various parts of the stamps, made hy machinery, to economize their cost and make perfect and exact parts. We can say they are thoroughly made for durability and nse. Mr. Hill is not only snecessful in making good stamps, but we should judge from appearances, is leading the trade in his lioe. They are also agents for Hill’s superior branding iron, for branding tool-handles, ete This instrument is very convenieut, desirable and cheap. The Messrs. Hodge & Co. makea fine exhibit of theiy goads at the Pavilion, near and just to the right of the fountain. Wary is a fashionable young lady like a sportsman ? Because she bags the hare, Wellington's Vegetable Cutter. The want of cheap portahle machinery for converting vegetahles into feed, has long heen felt,—a necessity that has been hut partially overcome by suhstituting hoiling in large kettles, which, besides heing a great inconvenience, is often expensive, the construction of a furnace, and the purchase of hoilers costing much more than the invention of which we speak—the Pacific agency of which is represented by Mr. F. B. Lamh, at 116 Jesse street, who has one of these cutters in the Fair, near the silk exhihition. The construction of this machine, as illustrated in the ahove cut, is very simple, and its action easy, reducing the vegetahles to suitahle fineness with little labor. The cheapness of vegetahles as feed for horses and neat stock, has not been availahle here to any considerable extent, for want of just such an invention. A change from the juceless grass fodder of the dry season to a partial feeding of vegetahles, must result favorahly in tho raising and fattening of stock for market, lessening the cost and improving the quality. It may also stimulate the raising of vegetahles in certain localities where, withont a cheap way of reduction, they would not be available. The machine cuts turnips, carrots, heets, potatoes, Wurtzels, pumpkins, etc., with the same ease, into gouge-shaped pieces, most snitahle for mastication. Thers are two sizes manufactured, the one on exhibition being of the smallest capacity. The largest is adapted to horse-power, with hopper capacity for four hushels. The agent mentioned ahove is a stirring and experienced one, and we are pleased to see him successful in selling so meritorious an article. The cutteris just what is wanted in a fast conntry like ours, where beets frequently grow over 100 1bs. in weight. It would be cruel to force cattle to swallow them whole. Waar anz “Brazmian Prespurs ?’—A special feature of Mr. Housewortb’s exhihition of optical instruments aud optical appliances at the Fair, which has heen overlooked, is his showing of Brazilian pebbles, and of the pure and perfect lenses which are manufactured therefrom, They are nothinghut pure crystallized silica without a flaw, and are not necessarily all Brazilian, hutas they have been found plentifully and very perfect in that couutry, a trade has sprung up forthe supply of the London and Paris lens manufacturers, who pay good prices for the mineral. Spectacle lenses were formerly all made of common glass, but they have been found to be much less pure, and at the same time to be more inflaming to the eyes, than the pure and cold natural product of the caverns of the earth. An examination with the tourmaline tongs or ‘‘ pebble trier” shows common glass to be almost dark, where the rock crystal is luminous; and ou touching them both to the tongue there is observable at once the most marked difference as to temperature. Brazilian pebble glasses cost the manufacturers ten times as much as the ordinary ) glasses, yet the price at which they are sold is only four times that of the latter—viz., $6 and $24 respectively. It is certainly unwise economy that would suhmit so delicate an organ as the eye to the use of imperfect or irritating glasses. For old people, there is a new thing exhihited, which is founded on a correct principle—a glass ground, with a different focus on the upper half from that of the lower half, adapting the spectacles to seeing both distant and near objects. Scraper and Tube Cleaner. The following is the patentee’s claims and description of the novel and ingenious i vention herewith illustrated. Itis the cheapest, best, most durable, easiest to adjust, and cleanest apparatus to use for ths pni pose designed, yet offered to the public, Being constructed on simple and mechan. ical principles, it is not liahle to get out of order, and will continue to perform its office until the materials are worn ont, It can readily be adjusted, even by any inexperienced person—will scrape off i scales and cleanse the tuhes just smooth and clean as they were when ne without in the least affecting their inn surface, as the Elliptic Spring Scraper hag a smooth square edge, andsprings in or ont to fit the tubes. . A coutinuous iron rod runs through ths center of the top and hottom hubs. Th soft steel scrapers are fastened with screws to the hubs, under the caps, which cover and protect the screws that fasten the seraj ers on the hub. The scrapers are expand or contracted by screwing or unscrewing the lower hub,—first loosening the cap. There is a collar onthe rod, with a set screw . in it to fix it firmly on the rod to prevent . the scrapers being jammed. An elastic or flexible brush or scraper, made of leather, t rubber, or some pliahle material, isattached . to the nut for the purpose of removing from the tube tho scale and dust loosened hy the action of the scrapers. These scrapers are made from one to six inches in diameter—the prices of those from one to three inches ranging from $5 . to$12. They are now extensively used in the Eastern States. Quite a number hays already been sold at the Union Youndry, Sacramento, giving the best of satisfaction. . They are on exhibition at the Mcchanies’ : Pair, by McAfee, Spiers & Co., boilsr makers, Howard street, between Fremont and Beale. Fo: PosITIon oF THE WRIST IN PLAayENe.— The ‘‘ Piano Pupil’s Monitor” is a device suggested by J. D. Patrick, a teacher of ex perience, for the purpose of insuring & proper position of the wrist in playing ths piano. A correct habit in this respect is deemed of importance to the permanent progress of the student. A bar or other contrivance attached to the piano, in front of the keys, for the support of the pupils wrists, is by no means a new invention; hutastrip armed with a bevel edge, not sharp enough to do any injury to the wrist, yet possessing a sufficient edge to render it an uncomfortable support for the wrist, ia claimed to possess both novelty and utility. Many distinguished professors have given their verdict against the use of any snpport for the wrist, and probahly no permanent benefit can he derived from the nse of such asupport; but there could be no harm ip having something which would remind the pupil when the wrist might be too low, without serving as a support for the wrist. Teachers or parents who may desire ths Pupil’s Monitor can economize hy leaving orders with the inventor, 326 Mason street, near Geary. The invention may be seen on Mr. Rudoif’s piano, at the Mechanics’ Fair. First-Cuass Grocertss are not only ths . best, but really the cheapest. The waste on second rate provisions, on an average, more than equals the difference in price. . Give your orders to Bowen Bros., and you . will get value received, not once, but every time,
