Part 13
It has been an opinion, that he who receives an estate from his ancestors, is under some obligation to transmit the same to posterity. This obligation lies not on me, who never inherited a shilling from any ancestor or relation. I shall, however, if it is not diminished by some accident before my death, leave a considerable estate among my descendants and relations. The above observation is made merely as some apology to my family, for my making bequests that do not appear to have any immediate relation to their advantage.
I was born in Boston, New England, and owe my first instructions in literature to the free grammar schools established there. I have, therefore, considered those schools in my will.
But I am also under obligations to the state of Massachussets, for having, unasked, appointed me formerly their agent, with a handsome salary, which continued some years; and although I accidentally lost in their service, by transmitting governor Hutchinson's letters, much more than the amount of what they gave me, I do not think that ought in the least to diminish my gratitude. I have considered that, among artisans, good apprentices are most likely to make good citizens, and having myself been bred to a manual art, printing, in my native town, and afterwards assisted to set up my business in Philadelphia by kind loans of money from two friends there, which was the foundation of my fortune, and of all the utility in life that may be ascribed to me--I wish to be useful even after my death, if possible, in forming and advancing other young men, that may be serviceable to their country in both these towns.
To this end I devote two thousand pounds sterling, which I give, one thousand thereof to the inhabitants of the town of Boston, in Massachussets, and the other thousand to the inhabitants of the city of Philadelphia, in trust, to and for the uses, intents, and purposes, herein after mentioned and declared.
The said sum of one thousand pounds sterling, if accepted by the inhabitants of the town of Boston, shall be managed under the direction of the select men, united with the ministers of the oldest episcopalian, congregational, and presbyterian churches in that town, who are to let out the same at five per cent. per annum, to such young married artificers, under the age of twenty-five years, as have served an apprenticeship in the said town, and faithfully fulfilled the duties required in their indentures, so as to obtain a good moral character from at least two respectable citizens, who are willing to become sureties in a bond, with the applicants, for the re-payment of the money so lent, with interest, according to the terms hereinafter prescribed; all which bonds are to be taken for Spanish milled dollars, or the value thereof in current gold coin: and the manager shall keep a bound book, or books, wherein shall be entered the names of those who shall apply for, and receive the benefit of this institution, and of their sureties, together with the sums lent, the dates, and other necessary and proper records, respecting the business and concerns of this institution: and as these loans are intended to assist young married artificers, in setting up their business, they are to be proportioned by the discretion of the managers, so as not to exceed sixty pounds sterling to one person, nor to be less than fifteen pounds.
And if the number of appliers so entitled should be so large as that the sum will not suffice to afford to each as much as might otherwise not be improper, the proportion to each shall be diminished, so as to afford to every one some assistance. These aids may, therefore, be small at first, but as the capital increases by the accumulated interest, they will be more ample. And in order to serve as many as possible in their turn, as well as to make the re-payment of the principal borrowed more easy, each borrower shall be obliged to pay with the yearly interest, one tenth part of the principal; which sums of principal and interest so paid in, shall be again let out to fresh borrowers. And it is presumed, that there will be always found in Boston virtuous and benevolent citizens, willing to bestow a part of their time in doing good to the rising generation, by superintending and managing this institution gratis; it is hoped that no part of the money will at any time lie dead, or be diverted to other purposes, but be continually augmenting by the interest, in which case, there may in time be more than the occasion in Boston may require; and then some may be spared to the neighbouring or other towns, in the said state of Massachusetts, which may desire to have it, such towns engaging to pay punctually the interest, and the proportion of the principal annually to the inhabitants of the town of Boston. If this plan is executed, and succeeds, as projected, for one hundred years, the sum will then be one hundred and thirty thousand pounds, of which I would have the managers of the donation to the town of Boston then lay out, at their discretion, one hundred thousand pounds in public works, which may be judged of most general utility to the inhabitants; such as fortifications, bridges, aqueducts, public buildings, baths, pavements, or whatever may make living in the town more convenient to its people, and render it more agreeable to strangers resorting thither for health, or a temporary residence. The remaining thirty-one thousand pounds I would have continued to be let out to interest, in the manner above directed, for one hundred years; as I hope it will have been found that the institution has had a good effect on the conduct of youth, and been of service to many worthy characters and useful citizens. At the end of this second term, if no unfortunate accident has prevented the operation, the sum will be four millions and sixty-one thousand pounds sterling, of which I leave one million and sixty-one thousand pounds to the disposition and management of the inhabitants of the town of Boston, and the three millions to the disposition of the government of the state--not presuming to carry my views farther.
All the directions herein given respecting the disposition and management of the donation to the inhabitants of Boston, I would have observed respecting that to the inhabitants of Philadelphia; only, as Philadelphia is incorporated, I request the corporation of that city to undertake the management, agreeable to the said directions: and I do hereby vest them with full and ample powers for that purpose. And having considered that the covering its ground-plat with buildings and pavements, which carry off most of the rain, and prevent its soaking into the earth, and renewing and purifying the springs, whence the water of the wells must gradually grow worse, and in time be unfit for use, as I find has happened in all old cities; I recommend, that, at the end of the first hundred years, if not done before, the corporation of the city employ a part of the hundred thousand pounds in bringing by pipes the water of Wissahickon-creek into the town, so as to supply the inhabitants, which I apprehend may be done without great difficulty, the level of that creek being much above that of the city, and may be made higher by a dam. I also recommend making the Schuylkil completely navigable. At the end of the second hundred years, I would have the disposition of the four millions and sixty-one thousand pounds divided between the inhabitants of the city of Philadelphia and the government of Pennsylvania, in the same manner as herein directed with respect to that of the inhabitants of Boston and the government of Massachusetts. It is my desire that this institution should take place, and begin to operate within one year after my decease, for which purpose due notice should be publicly given, previous to the expiration of that year, that those for whose benefit this establishment is intended may make their respective applications: and I hereby direct my executors, the survivor or survivors of them, within six months after my decease, to pay over the said sum of two thousand pounds sterling to such persons as shall be duly appointed by the select men of Boston, and the corporation of Philadelphia, to receive and take charge of their respective sums of one thousand pounds each, for the purposes aforesaid. Considering the accidents to which all human affairs and projects are subject in such a length of time, I have, perhaps, too much flattered myself with a vain fancy, that these dispositions, if carried into execution, will be continued without interruption, and have the effects proposed: I hope, however, that if the inhabitants of the two cities should not think fit to undertake the execution, they will at least accept the offer of these donations, as a mark of my good will, token of my gratitude, and testimony of my desire to be useful to them even after my departure. I wish, indeed, that they may both undertake to endeavour the execution of my project, because I think, that, though unforeseen difficulties may arise, expedients will be found to remove them, and the scheme be found practicable. If one of them accepts the money with the conditions, and the other refuses, my will then is, that both sums be given to the inhabitants of the city accepting; the whole to be applied to the same purposes, and under the same regulations directed for the separate parts; and, if both refuse, the money remains of course in the mass of my estate, and it is to be disposed of therewith, according to my will made the seventeenth day of July, 1788.
My fine crab-tree walking-stick, with a gold head curiously wrought in the form of the cap of Liberty, I give to my friend, and the friend of mankind, General Washington. If it was a sceptre, he has merited it, and would become it.

LETTERS AND PAPERS
ON
_ELECTRICITY_.
_It may not be improper to present the reader with the following extract from the preface to the first edition of Dr. Franklin's papers on electricity, which, as we have stated in the advertisement, formed a pamphlet only._
_"The following observations and experiments were not drawn up with a view to their being made public, but were communicated at different times, and most of them in letters, written on various topics, as matters only of private amusement._
_"But some persons, to whom they were read, and who had themselves been conversant in electrical disquisitions, were of opinion, they contained so many curious and interesting particulars relative to this affair, that it would be doing a kind of injustice to the public, to confine them solely to the limits of a private acquaintance._
_"The editor was therefore prevailed upon to commit such extracts of letters and other detached pieces as were in his hands to the press, without waiting for the ingenious author's permission so to do; and this was done with the less hesitation, as it was apprehended the author's engagements in other affairs would scarce afford him leisure to give the public his reflections and experiments on the subject, finished with that care and precision, of which the treatise before us shows he is alike studious and capable."_
_With respect to the general merit and originality of the experiments and hypothesis of Dr. Franklin, as described and explained in these letters, the following is the testimony of one of the first natural philosophers of his age--the late Dr. Priestly, in his History of Electricity._
_"Nothing was ever written upon the subject of electricity which was more generally read and admired in all parts of Europe than these letters. There is hardly any European language into which they have not been translated; and, as if this were not sufficient to make them properly known, a translation of them has lately been made into Latin. It is not easy to say, whether we are most pleased with the simplicity and perspicuity with which these letters are written, the modesty with which the author proposes every hypothesis of his own, or the noble frankness with which he relates his mistakes, when they were corrected by subsequent experiments._
_"Though the English have not been backward in acknowledging the great merit of this philosopher, he has had the singular good fortune to be, perhaps, even more celebrated abroad than at home; so that, to form a just idea of the great and deserved reputation of Dr. Franklin, we must read the foreign publications on the subject of electricity; in many of which the terms_ Franklinism, Franklinist, _and the_ Franklinian system, _occur in almost every page. In consequence of this, Dr. Franklin's principles bid fair to be handed down to posterity as equally expressive of the true principles of electricity, as the Newtonian philosophy is of the true system of nature in general."_

INTRODUCTORY LETTER.
_Philadelphia, March 28, 1747._
SIR,
Your kind present of an electric tube, with directions for using it, has put several of us[15] on making electrical experiments, in which we have observed some particular phenomena that we look upon to be new. I shall therefore communicate them to you in my next, though possibly they may not be new to you, as among the numbers daily employed in those experiments on your side the water, it is probable some one or other has hit on the same observations. For my own part, I never was before engaged in any study that so totally engrossed my attention and my time as this has lately done; for what with making experiments when I can be alone, and repeating them to my friends and acquaintance, who, from the novelty of the thing, come continually in crowds to see them, I have, during some months past, had little leisure for any thing else.
I am, &c.
B. FRANKLIN.

_Wonderful Effect of Points.--Positive and negative Electricity.--Electrical Kiss.--Counterfeit Spider.--Simple and commodious electrical Machine._
_Philadelphia, July 11, 1747._
SIR,
In my last I informed you that, in pursuing our electrical enquiries, we had observed some particular phenomena, which we looked upon to be new, and of which I promised to give you some account, though I apprehended they might not possibly be new to you, as so many hands are daily employed in electrical experiments on your side the water, some or other of which would probably hit on the same observations.
The first is the wonderful effect of pointed bodies, both in _drawing off_ and _throwing off_ the electrical fire. For example,
Place an iron shot of three or four inches diameter on the mouth of a clean dry glass bottle. By a fine silken thread from the cieling, right over the mouth of the bottle, suspend a small cork-ball, about the bigness of a marble; the thread of such a length, as that the cork-ball may rest against the side of the shot. Electrify the shot, and the ball will be repelled to the distance of four or five inches, more or less, according to the quantity of electricity.--When in this state, if you present to the shot the point of a long, slender, sharp bodkin, at six or eight inches distance, the repellency is instantly destroyed, and the cork flies to the shot. A blunt body must be brought within an inch, and draw a spark to produce the same effect. To prove that the electrical fire is _drawn off_ by the point, if you take the blade of the bodkin out of the wooden handle, and fix it in a stick of sealing-wax, and then present it at the distance aforesaid, or if you bring it very near, no such effect follows; but sliding one finger along the wax till you touch the blade, and the ball flies to the shot immediately.--If you present the point in the dark, you will see, sometimes at a foot distance and more, a light gather upon it, like that of a fire-fly, or glow-worm; the less sharp the point, the nearer you must bring it to observe the light; and at whatever distance you see the light, you may draw off the electrical fire, and destroy the repellency.--If a cork-ball so suspended be repelled by the tube, and a point be presented quick to it, though at a considerable distance, it is surprising to see how suddenly it flies back to the tube. Points of wood will do near as well as those of iron, provided the wood is not dry; for perfectly dry wood will no more conduct electricity than sealing-wax.
To shew that points will _throw off_[17] as well as _draw off_ the electrical fire; lay a long sharp needle upon the shot, and you cannot electrise the shot so as to make it repel the cork-ball.--Or fix a needle to the end of a suspended gun-barrel, or iron-rod, so as to point beyond it like a little bayonet[18]; and while it remains there, the gun-barrel, or rod, cannot by applying the tube to the other end be electrised so as to give a spark, the fire continually running out silently at the point. In the dark you may see it make the same appearance as it does in the case before-mentioned.
The repellency between the cork-ball and the shot is likewise destroyed. 1. By sifting fine sand on it; this does it gradually. 2. By breathing on it. 3. By making a smoke about it from burning wood[19]. 4. By candle-light, even though the candle is at a foot distance: these do it suddenly.--The light of a bright coal from a wood fire; and the light of a red-hot iron do it likewise; but not at so great a distance. Smoke from dry rosin dropt on hot iron, does not destroy the repellency; but is attracted by both shot and cork-ball, forming proportionable atmospheres round them, making them look beautifully, somewhat like some of the figures in Burnet's or Whiston's Theory of the Earth.
_N.B._ This experiment should be made in a closet, where the air is very still, or it will be apt to fail.
The light of the sun thrown strongly on both cork and shot by a looking-glass for a long time together, does not impair the repellency in the least. This difference between fire-light and sun-light is another thing that seems new and extraordinary to us[20].
We had for some time been of opinion, that the electrical fire was not created by friction, but collected, being really an element diffused among, and attracted by other matter, particularly by water and metals. We had even discovered and demonstrated its afflux to the electrical sphere, as well as its efflux, by means of little light windmill-wheels made of stiff paper vanes, fixed obliquely, and turning freely on fine wire axes.
Also by little wheels of the same matter, but formed like water-wheels. Of the disposition and application of which wheels, and the various phenomena resulting, I could, if I had time, fill you a sheet[21]. The impossibility of electrising one's self (though standing on wax) by rubbing the tube, and drawing the fire from it; and the manner of doing it, by passing the tube near a person or thing standing on the floor, &c. had also occurred to us some months before Mr. Watson's ingenious _Sequel_ came to hand, and these were some of the new things I intended to have communicated to you.--But now I need only mention some particulars not hinted in that piece, with our reasonings thereupon: though perhaps the latter might well enough be spared.
1. A person standing on wax, and rubbing the tube, and another person on wax drawing the fire, they will both of them (provided they do not stand so as to touch one another) appear to be electrised, to a person standing on the floor; that is, he will perceive a spark on approaching each of them with his knuckle.
2. But if the persons on wax touch one another during the exciting of the tube, neither of them will appear to be electrised.
3. If they touch one another after exciting the tube, and drawing the fire as aforesaid, there will be a stronger spark between them than was between either of them and the person on the floor.
4. After such strong spark, neither of them discover any electricity.
These appearances we attempt to account for thus: We suppose, as aforesaid, that electrical fire is a common element, of which every one of the three persons abovementioned has his equal share, before any operation is begun with the tube. _A_, who stands on wax and rubs the tube, collects the electrical fire from himself into the glass; and his communication with the common stock being cut off by the wax, his body is not again immediately supplied. _B_,(who stands on wax likewise) passing his knuckle along near the tube, receives the fire which was collected by the glass from _A_; and his communication with the common stock being likewise cut off, he retains the additional quantity received.--To _C_, standing on the floor, both appear to be electrised: for he having only the middle quantity of electrical fire, receives a spark upon approaching _B_, who has an over quantity; but gives one to _A_, who has an under quantity. If _A_ and _B_ approach to touch each other, the spark is stronger, because the difference between them is greater: After such touch there is no spark between either of them and _C_, because the electrical fire in all is reduced to the original equality. If they touch while electrising, the equality is never destroyed, the fire only circulating. Hence have arisen some new terms among us; we say _B_, (and bodies like circumstanced) is electrised _positively_; _A_, _negatively_. Or rather, _B_ is electrised _plus_; _A_, _minus_. And we daily in our experiments electrise bodies _plus_ or _minus_, as we think proper.--To electrise _plus_ or _minus_, no more needs to be known than this, that the parts of the tube or sphere that are rubbed, do, in the instant of the friction, attract the electrical fire, and therefore take it from the thing rubbing: the same parts immediately, as the friction upon them ceases, are disposed to give the fire they have received, to any body that has less. Thus you may circulate it, as Mr. Watson has shewn; you may also accumulate or subtract it, upon, or from any body, as you connect that body with the rubber or with the receiver, the communication with the common stock being cut off. We think that ingenious gentleman was deceived when he imagined (in his _Sequel_) that the electrical fire came down the wire from the cieling to the gun-barrel, thence to the sphere, and so electrised the machine and the man turning the wheel, &c. We suppose it was _driven off_, and not brought on through that wire; and that the machine and man, &c. were electrised _minus_; _i. e._ had less electrical fire in them than things in common.
