A NATIONAL PAPER, PUBLISHED WEDNESDAYS AND SATURDAYS BY JOHN FEN NO, No. 69, HIGH-STREET, PHILADELPHIA Wednesday, August 8, 1792. [Whole No. 452.] 77 Or\ tin ufti that max be made of Coutchouc* Guvty or Indian Rubber, in Arts and Manufactures,' an account of the manner of obtaining and md nujacluring it. (concluded.) 6th. A F.ROSTATION is now nearly at a stand ; xa. but it is wonderful rjo one ever per ceived the use that might have been made of this substance for that purpose. No kind of silk, or other light substance could ever be found, that pot fetfed the fmaileft degree of elasticity ; by confe r quence, when they afcendcd into thp higher Re gions, the expanfioa of the gas was in danger of buifting the globe ; it was therefore neceffarv t<j> leave it open below to guard against that accident. A globe of coutchouc would have polfeffcd the quality here wanted ; it would have expanded as the circumstances of ih? cafe required ; and while it was perfe&ly to prevent the involuntary escape of the fmaileft quantity, it would have adapt ed itfelf in size to every variation of circumstances. It is true, the retentive power of this substance, when very thin, has nevei y>et been afcertaiijed by experience ; but there is reason to believe it ii ve» rv great. ' 7th. As this substance is inflamable, and burns with a bright/lame withoyt requiring ?ny wick, it might be employed perhaps with great economy as torches or flambeaux. Solid balls have also been made of it, that are light, and of an amazing de gree of elasticity ; but what ufeful purpose could be made of these, does not at present appear It might also be moulded into the foipi of riding whips, and would probably answer that purpose admirably well ; and after they wefe wore oy.t, they might be employed a« torches. ,Bth. As a material for chiryrgicpl purpofos, it might be employed on occasions. Catheters ( have already been made of it, after having been dissolved in aether, that have been found to answer the purpose wanted, and to occasion irlueh less ir ritation in the parts than those of wiy other fort that have yet been tried ; but the great price, \yben thjus manufafturcd, prevents them from cowling into general use. The little bottles, when applied to the breads of women distressed with fore nip-r pies, can be so managed,.as to occa&on a more gentle fufliou than fatf be any other \v?y, and have therefore afforded v.eiy great relief. In ftiort, the variety of uses to which they might be applied, as bags for in jewing or 4or fucking", are too numerous, to adm.ut of being there so much as pointed at. 9th. Elajlic springs. In all cases where a fp,ring is wanted to att by us contrflflijc power, no sub stance can be conceived niore proper, than that of which we now speak, especially in coid climates ; and there are innumerable cases in which it might be employed in this tnanner with the happjelt effect, in various kinds of machinery. 10th. It is many years since Dr. Bcrgius at Stockholm, made some experiment# on this sub stance in Pa pita's digester : By fubje&ing ij in that way to an intense degree of heat, it is said to have beeaconvcitcd into a hard, eUftic, horn-ljke fub ftrnce. I have not heard that these experiments have been repeated ; but if upon farther trial, this' fhajl be found to be invariably thercCult, it would! extend the utility of this substance, far beyond the limits we have hitherto thought of; but in the state of uncertainty that at present prevails on that head, it would be improper so fay more. I might go on at this rate for many pages toge ther, pointi/ig out varjpus other uses to which it might be applied ; but J (hall content myfelf with fpecifying one other only. Geographical globes are at present an article of ex pence, jMpecjalJy when of such a as to admit of exhibiting a tolerable view of the earth'* furfact. These could be ijiade of coutchouc of a-ny size required, at a very moderate ex pence. The favagesot America whom cuir philosophers repre sent as destitute of every fTventaJ endow ment, will teach us the way of proceeding. Thd little bottles we import fropi thencc„ arc formed upon m®ulds of clay dried in the fun. When the coutchouc has hardened on the furfacc bv the process already <Jefcri.be(d, a little water is introduced at the mouth of the bottjc, which gra dually foftens the clay, and in time allows it to be wafticd entirely out of it. A globe of clay might be eafiJy moulded of any dimensions required, leaving at one of the pplej a small protuberance for a little neck. Tbis ball, when dry, might be co vered wiih coutchouc till it acquired the thickness required ; and lor the purpose here wanted, this might be very thin. The clay miglut tiien be washed out, so as to leave it empty. The re mainder of the proccfs might be here defenbed. were I not afraid of encroaching too much on the patience of the reader. It now only remains, I should give the reader some notices concerning the uec U>at produces this singular substance. In no one instance that I knpw has the inatten tion of mankind to ufeful improvements been more conspicuous, than with reipedt to the object of our present dilcuflion. It is not inudh lels than sixty yeais since Mr. <le li Condamine firft jnnde known to Europeans t,his lingular fubftauce, which poflt*ff< s qualities that obviously render it one of the mod uleful bodies that hath evei come to the knowledge of man tor many important purposes in life ; yet the culture of the plant which affords it, has been, till this moment, entirely negleded by every European nation ; nor do I believe, that ever a Tingle feed of it was planted by one person in the univcrfe. Tbe tree which yields this juice is large and (lately. Its trunk is uiually about 60 feet in heigh, and from two to three feet diameter. It grovs naturally in Brazil, in French Guiana, and m Cceral other provinces of South America, and alfou China, as it is fupjwfcd. It is called by the natives liebea 4 mid Mr. A'lVrt has preserved "that name. He calls h Hevta Qnvrnifis. It is iiie Pao Seringa, act. Paris, an. 17&U faTr»f)f*z Jriia terpatis clhpficis integfrfimiffybtiis c/i-ni\ pftio- Utis. Lin,—The form of its and botanical charafleriftirs, will be veil underftooc 5 by the ; plate. Its feed is a nut, o c a pleating tane, veVv ! much resembling thatot a filbert, afifl ttiucb ettdefr)- ed by the natives. The fee grows very freely, ?nd might doub l l { (V be eafijy reared, wsrc ieejds brought higher for that purpofr, either in fame of the focxy parts of our Weft-India islands, or the Cape Verd lflands, or along the coafU of Africa, where there arc such extensive tr?£ls of uninhabited country Jaid waste by the depopulation tjhat ovr deflru&tve trade in Haves occasions. What a dif ference would there be in theftate of the inhabit ants of that unhappy Country, were they to be taught to cultivate the arts of pea.ee, and to .enrich I thcmfelves by industrious labour, inftesd pi tharfs I cruel wars fomented by our m.ifcrablc tr-ade in Haves. Could this juice be had in abundancefo near to Europe, it might He sent here in iVs fluid state in clpfe cpfks or bottle®, so as to br here ma nufa&ured for the purposes it were fitted to au fwcr. Several other trees in phofe regions afford jui ccs approaching to the nature of the routchouc, though differing it in certain refpe&s, which might be applied to other uses in life ; but an ac count of thtfe shall be reserved for another occa iion. ~ [CIRCULAR.J Philadelphia, 9<£ Augujl t « 7^2, SIR, BY the inclosed copy of the minutes of the pro ceedings of a general .meeting of the citizens of Philadelphia, you will perceive, that the citi zens arc desirous to obtain information, 11 of tljc sense of the people in the different parts of the ftete, rcfpe&ing the chara&crs proper to be nomi nated as Representatives inCongrcfs, and Electors of a Prfficicnt and Vice-Prefid.tDt o f the Unitfjd States; and th»t they have committed to us, the tafkofendeavoringto coll?6lt.he materials, op which I their judgment and choice, in this important bufi | ness, may be fairly, independently, and fatisfac torily cxercifcd.

A RECIPE FOR KILLING RATS. In 1783* a premium of fivegunineas was giv en by the Dublin Society for the following re cipe to kill Rats. Take r quart of oatmeal, 4 drops of oil of I grain of miifk, 2 nuts ofnux vomi ca powdered. Mix the whole together, and place it where the rats frequent; continue to do so while they eat it, and it will soon destroy them, be they ever so numerous. Time, fays a late French writer, isuniverfal property —to make good use of it, is the firft of all riches. Even those who poilefs nothing, have an in terest to fee property protected ; for visible goods alone, such as money, furniture, houfei, lands, Set. are not the only property—the love of labor, induftrv, are alio filnds of which the product is property; and this is perhaps th<? moit valuable kind.
