SELECTING SEED CO EN. * Every one is acquaint* d with the fact, that plants of any variety, grown from seeds obtained in a higher lati'udo, or what is in eff-ct the same thing, a greater elevation will come to maturity, and ripen their seeds earlier, than when the process is reversed, and the soeds nre obtained from a lower latitude,-or more depressed position. In no plant is the effect more. conspicuous than in corn,.and the present season has afforded numberless opportuoi ies of testing the truth of^the tlrory. Where corn has been bTwg'it from the vallies to the bills and planted, it hn been uniformly later in tas 1!- 1 '* .U?. at ?hf?

Admitting Mr. Thocburohr statement of the growth of his China tree corn, and the ttme of its being fit for boiling to be correct; that corn, distributed over the north from Long Island, and some of it planted at much greater elevations, furnishes the most striking proof of the impolicy of selecting seed corn from a more southern region that ire havo yet seen. On the line of the Erie canal, two'degrees further north by latitude, " and one more by elevation. (ftOO feet in el, inttMMi being considered equal to a degree,) the corn irhttrh was fit to boil by (he tenth of July on Lbng Island had scarcely silked by the tenth of August, und would show few roasting or boiling ears by the first of 3cplember. Another instance we find in the August Ctflii valor. Judge Buel says?

We otanted wi h this seed eight rows across our field, the residue tF'ing planted witn com of our own raising.

Well filled ears; those that hive two or more} on 4 stalk ; and that r pen the earliest ; will be found t# be best and most productive, and should be chosen at .the proper season, without lea v. tag any thing to after selection or chance.

The price brought by Mr Physick'g trees sold at auction near Philadelphia in September induced others to advertise their trees to be sold also at auction. But before the tinc? of the sales arrived the suspension of specie payments in Philadelphia and other places with an unprecedented scarcity of money came on, and trees forced off at auction lilro all other articles not wanted for immediate use, brought next to nothing. By those who manage more judiciously* however, sales are still made at good prices. Air.

For some years a little slender man, whose attire denoiod ^>overtT? was obsrcxed ia Uia"11n? tforttn, wrrcre Tie was to be seen every week. Instead of walking through the galleries and examining the various paintings, ha was in the Flemish room, stationed before the same pictoro, a portrait of Rembrandt. He would remain there, for hours together, his hands behind his back, end his eyes fixed upon the picture. This was ascribed to excentricity, whilst it was a serious and singular study, leading to a discovery which will form an era in the hisory of pointing. Mr. Leipmao was meditating upon the in. vention of a machine for reproducing oil paintings ; and, after ten y?ars of persevering labour, he has succeeded beyond all expcctation. At his residence nro to be seen above a hundred copies of thnt very head of Rembrandt, all of them of scrupulous re. semblance to another. Ho#he has achieved this, is his own secrot. When onoeonsiders what privations he must have suffered in realizing his idea, one cannot help wishing that tits fcflbrts may be rewarded. With the assistance of a trust-worthy maidservant, he has laboured for many years, n'ght and day, making sealing wax at night to mike n livelihood. Tlie most surprising circumstance is, that he did not preciously make a complete copy of the picture, but conveyed it home by part*, as he had it in his mind after visiung the Museum. Thus, on one day it was an eye, on another the nose, on a third a lock of hair that he took i home, which must have required wfiole years for the completion of his task. Ho has procured with his machioe, in one of the rooms of the Royal Museum, and in presence of the directors, 110 co, ies of Rembrandt's portrait, painted by himself? a picture, the copying of which in the usual ' way presents tho utmost difficulties, according to tho opinion, of all painters. Lcipman's copies are said to be perfect, and to give the most delicate shades of the colour, lie asks but a louis d'or for a copy, (lis invention excites universal admiration. THB PREDICTION. The celebrated Dr. B ?fkf this TTorlvention being to oewse sonn neans to protect in future, a molt import int American Interest, we pnss at once ti ts considera ion. It may not to' out of place to advert t< hat derangement in the momentary systen >f the United States, which, in 1837, led ti i suspension of specie payments throughou he Americnn Republic. At that time ou :ountry owed the excess in value of thi mports over the exports of the Unite Suites, in their trade with England. To pay this balance in specie, was im jracticable. An unusually favorable son ion had given us a crop of unprecedente ibundance in the co!ton growing stntes.Fo transmit this property to tho country c aur great creditor, as fast ns possible, as a avidence that the cit z?ns of the Unite States were neither wanting in the mear nor the disposition to redeem all their obi gations, the aid of the Banking Institutior of the Union was invoked, and to guard part of the property so transmitted, throug their instrumentality, from unnecessary sa< nfice in the market of consumption, tf agency of Humphries and Biddle was et tabltshed in Liverpool. The result of th1 agency in winding up the large crop < 1838, is conclusive proof of whut may t done by consignees thoroughly devoted l American interests, suhjeci to no necessit by heavy advances, to glut the market b forcing upon it large stocks in constant an disastrous succession. In this brief outline, is embraced tt th establishment of litis agency for the dbfenc of our great staple had been removed, th trade would fall back into his old dhnneh and that the proociion for our interest would be ample, with the meansojlbe com mand of individuals engaged in it No one sought to prevent this.

Nothing harbcen saic or done, Sy the so called "moiopolis," t prevent others from entering into a fai competition with them. But we have, unfortunate!), been obligei to learn by a severe lesson, dat other coun trios, as well as our own, may, at timei be destitute of nn adequat# supply of th< precious metals. We huv* to reuhza tlx painful truth that after devsting our capital our anxious attention and tur labor, tj pro duce a good cropt and after witnessbg th< partial disappointment of our hope* fron the unfavorable influence of the dementi in our own country, the value of vhat w< have secured is to be essentially difttinisher by the extent, or deficency, of a differen crop in another countiy.

It will be perceived, io the sequ r that so far from desiring to force, orsedu 2 the Banks into the risks of commercial a i ventures, that we do not propose to th< to do any thing more than perform th< . usual function of tending mon-y with . augmented security. In one word we pi j pose that the Banks of the Southern Sta . should commence forthwith to make advr ,f ces on Cotton on the pledge, in a praccic n hie form of the mapriul itself; with I d personal security of the persons taking I s advance. i.

The truth is, the I e resumption was premature.

Shall t in the process of this exchange allow oihi to reap the benefits of this conversion ; a . moment too. when our Banks require a i I flux of bullion into their coffers or equivalent in foreign exchange, in ord-r lit at no distant day, they may redeem th< faith with the public ? If the Banks in t Southern Slates, advanced on the whe Cotton crop of our country, it is quite ob ous that they would, through the foreign c changes, have what Would he equivalent a supply annually, of eighty millions of t precious metals.

And wt hove no hesitation in say it that we believe if the Banks of the Sou come forward promptly and generally, at make advances, at sate rate3, to responsil parties, on our crop that the most stupo dously beneficial change will be effected i the currency trade, and exchanges or 01 section of the Union that has ever barb cor sumrnatcd.

We are aware, bow-? jr ever, we should not perform our duty, or hi very inadequately meet public expectation, i. if we did not point out, practically, the modo by which these desirable objects are to bejs accomplished. to First, it i* proposed at all the principal ie shipping ports of the cotton States, that parn* ties, whether planters, cotton merchants or n. factors, should apply to the Hanks for such re an advance on the cotton they hold, as may, a be in contormity with the current rates and ? 1). t>e mutually agreeable to the parties.
