F-XIIIRITION OF MANUFACTURE?. 



The Franklin Institute of Pennsylvania have 

 pfiven notice to the Manufacturers, Mechanies, 

 Artists, fee. of the United elates, that their first 

 exhibition will be held in Philadelphia, on the 

 18th, 19th, and 20lh of October next, to which 

 they invite " all who reside in the Union to send 

 the productions of their industry and ingenuity." 

 They also offer premiums for particular arti- 

 cles of manufacture ; and among others, the fol- 

 lowing: — 



To the maker of the best Cast Steel, who 

 has manufactured the same in any state of the 

 Union, — a specimen of at least 10 Jbs. in bars 

 of one half inch square or smaller. The quRli- 

 fy of steel and neatness of the bars will be con- 

 sidered in estimating its merit — A silver medal. 



To the manufacturer of the best specimen of 

 Cast-iron Pipes made in the United States. — 

 The pipes not to be less than 100 feet of one 

 inch calibre, in joints of at least four feet long, 

 joined by screwing into each other, or united as 

 effectually by some other mode — i silver medal 



To the person who shall manufacture the 

 best Crucibles of earthen ware, or other cheap 

 material, suitable for Brass Founders. The cru- 

 cibles must be made to endure as high a heat as 

 ■ those made of black lead, and to stand at least 

 seven heats in a brass founder's furnace. The 

 crucibles to be capable of holding at least 40 lbs. 

 of metal; one dozen of crucibles to be exhibit- 

 ed — A silver medal. 



To the maker of the best Smith's Anvil, steel 

 faced, not weighing less than 70 lbs. — A iilver 

 medal. 



To the manufacturer of the best piece of 

 Broad Cloth ; not less than live yards to be ex- 

 hibited — .'3 silver medal.

To the author of the best Treatise, (whether 

 in manuscript or printed,) on the construction 

 of Water Wheels. In appreciating the merits 

 of this work, regard will he had to procuring 

 the greatf^st effect with the water employed. It 

 is important also that the style should be intelli- 

 gible to common workmen-^jl silver medal. 



Premiums will also be awarded for articles 

 not specified, " which are remarkable for nov- 

 elty in the invention, or perfection in the work- 

 manship." 



The name and place of residence of the ma- 

 ker of or manufacturer must be affixed to the 

 article. Samples will be received of such arti- 

 cles as from their bulk or nature cannot be con- 

 veniently removed.— Persons desirous of ob- 

 taining further information on the subject can 

 address David II. Mason, No. 33, South Fourth

Orj THE FRE?ERVATION OF HARNESS. 



Sir, — Allow me to recommend the following 

 method of preserving leather harness and traces, 

 engine hose, boots and shoes, cording, sheep 

 nets, cart covers, stack cloths, &c., in the most 

 effectual manner, to the attention of your agri- 

 cultural readers, as an invaluable acquisition. 

 Take of neats' foot oil one quart ; bees wax, 

 cut small, one ounce; oil of tar, [spirits of tur- 

 pentine] half a ponnd by weight; and after sim- 

 mering the neats' oil a little in a pipkin, the oil 

 of tar must be added, when, after a gentle sim- 

 mering again for a few minutes, stirring it the 

 whole time with n stick, the mixture will be 

 finished; at the same lime, if an ounce of nap- 

 tha be comeatable, and the purpose for which 

 it is to be used should render the expense no 

 object, the composition will, by the addition 

 thereof, receive considerable improvement. It 

 is used precisely as oil would be applied ; and 

 where it may be required to soften old and hard- 

 ened leather, a washing or sponging with hot 

 wafer first is advisable, and the liquid should be 

 driven in before the fire. 



Leather or cordage dressed with this liquid 

 never rots, hardens, grows mouldy, or perishes 

 with blackinsf: it is likewise a complete des- 

 troyer of scahhiness in sheep and other animals. 

 I gave the form, about seven years back, to a 

 person who made a benefit of its sale in town, 

 and afterwards, contrary to a pledge given me, 

 sold the same to two people who now retail a 

 very inferior composition. 



As to the expense, one application of this flu- 

 id is superior to four or five of oil. 



Where the rendering leather water-proof is 

 desirable, the ounce of napiha proposed to be 

 added, should have a drachm of India rubber dis- 

 solved in it; for if should be remembered that 

 those things which give suppleness to leather, 

 open its pores; whereas, fo make it wafer-proof, 

 the closing them up by astringent applications, 

 or filling them up by waxy or gummy ones, is 

 indispensable. It is perhaps right to add, nap 

 tha is highly inflammable, and therefore should 

 be kept from the fire and candle, and added 

 "• oyier the mixture is taken from the fire." 

 I am, Sir, your very obed't serv't, 



W." M. DINSDALE.

HARD WATER FOR IRRIGATION. 

 In Parkes' Chemical Essays, page 9, it is as- 

 serted that " according to Dr. Home, hard wa- 

 ter promotes the growth of plants in a much 

 greater degree than soft water." Sir John Sin- 

 clair says, '■' In regard to waters much impreg- 

 nated with iron, they were formerly supposed 

 totally unfit for the purposes of irrigation ; but 

 it is now fully proved, by the accurate experi- 

 ments of aa able chemist, and by the extraordi- 



nary growth of grasses In Prisley meadow in 

 Bedfordshire, that ferruginous waters are friend- 

 ly to vegetation, when properly applied." We 

 believe that many if not the greater part of 

 what we call hard waters in this country iire 

 rendered hard by sulphate of lime, fcypsiim] 

 and are the more fit for irrigation from the ve- 

 ry circumstance uhich causes them to be im- 

 proper for bleaching, the use of the dyer and 

 most culinary purposes. 



PURIFYING OIL. 

 The property which tan has of combining 

 with gelatine, and therewith forming an insolu' 

 ble precipitate, may be applied fo the impor- 

 tant purpose of purifying rancid fish oil. I 

 knew a gentleman who fitted a very complete 

 apparatus with this intention ; and by agitating 

 the oil with the tannin and water in a large 

 vessel, to which he gave a rotary motion, the tan- 

 nin became intimately combined with the gelatir- 

 ous impurities, and then completely subsided. By 

 this means the oil, which was fit only for burn- 

 ing in the street lamps, was rendered free from 

 smell nearly equal to the best spermaceti oil, 

 and lit for burning in the closest chambers.

La Fayette. — Mr. Persico an accomplished ar- 

 tist (>f this city, has just completed in clay a co- 

 lossal bust of General La Fayette. Gentle- 

 men who have seen the original pronounce it 

 to be an admirable likeness. We can only bear 

 testimony to the excellence of the workmanship. 

 The countenance is strongly marked, and ex- 

 tremely interesting. Mr. Persico intends soon 

 to fiifish the cast in plaster; but would previous- 

 ly hi happy to have connoisseurs in the art call 

 at his rooms, No. 19, Murray-street, to examine 

 the bust, and suggest any alteiations — JV. Y.

inland Trade.— The Rochester Telegraph 

 contains a respectable marine list, annou'ncing 

 arrivals and departures at that port (on Genes- 

 see river) of a number of steam boats, tVom and 

 to Presque Isle, Sackett's Harbour, Ogdensburg, 

 Lewiston, Niagara, Cape Vincent, Port Hope, 

 and other places in the lake country, of too re- 

 cent designation to be found on any map, with 

 produce and merchandise of various kinds. — ib. 



Knowledge is Power.—" It is an excellent 

 opinion of the writer who obtained a prize 

 from the Economical Society of Berne, for an 

 Essay on the best means of instructing the pub- 

 lic, that ' a labourer executes easily and ex- 

 actly all his works in proportion fo his knowl- 

 edo'e.'" [Parkes'' Chemical Essays. 



Mistakes in Science. — " A person who means 

 to serve the cause of science effectually, must 

 often hazard his own reputation so far as to risk 

 mistakes in things of small moment."

A'o Man is too old or too -well informed to 

 learn. — Cardinal Farnese one day found Michael 

 Angelo, when an old man, walking alone in the 

 Colliseum, and expressed his surprise at finding 

 him solitary amidst the ruins; fo which he re- 

 plied, " I go yet to school that I may continue 

 to learn."
