CHAPTER XI

Spence's Experiments in Electricity. Franklin repeats them. Makes important Discoveries. Letters to Collinson. Experiment with the Kite. Publication of his Letters. Anecdote of the Abbé Nollet. Fame of Franklin. Elected a Member of the Royal Society.

1. It was in the year 1746, that Franklin first attended to the branch of philosophy in which he afterwards became so distinguished. During that year he was in Boston, and there met with a Dr. Spence, who showed him some experiments in electricity. It was a subject altogether new to him, and, though the experiments were not very well performed, they surprised and pleased him.

2. If you take a stick of sealing-wax, or a glass tube, or a piece of amber which has been a long time untouched, and bring it near some small pieces of paper, chaff, or other light substance, it produces no impression upon them. But if you first rub lightly and briskly the wax, the tube, or the amber, with a piece of dry woollen cloth, or cat skin, and then bring it near any of these light substances, you will find that they fly to it, and remain upon it. The power which attracts these substances, and which is excited by the rubbing, is called electricity.

3. It is so called from a Greek word which signifies amber, the substance in which this power was first observed. Amber is a brittle mineral substance, of a yellow, and sometimes a reddish brown color. It is found in several countries in Europe, and has recently been found in the United States, at Cape Sable, in Maryland. This is the substance with which the first electrical experiment was performed, ages ago, by a Greek philosopher of the name of Thales.

4. Several centuries passed without any thing being known upon this subject, beyond the fact that these substances possessed this power. At length it began to attract the attention of modern philosophers. In 1742, several ingenious Germans engaged in the subject, and the results of their researches astonished all Europe. They obtained large apparatus, by means of which they were enabled to collect large quantities of the electric fluid, and produce several wonders which had been before unobserved.

5. These experiments excited the curiosity of other philosophers. Mr. Peter Collinson, fellow of the Royal Society of London, about the year 1745, sent to the library company of Philadelphia a glass tube, with some account of its use in making such experiments. Franklin eagerly seized the opportunity of repeating those which he had seen at Boston, and, by much practice, acquired great readiness in performing those of which they had an account from England.

6. He was soon enabled to make a number of important discoveries, and his house was, for some time, continually full of people who came to see the new wonders. His observations upon the subject were, from time to time, communicated to his friend Collinson, in a series of letters, the first of which is dated March 28, 1747. These were read before the Royal Society, where they were not at first thought worthy of much attention.

7. In the year 1749, Franklin first suggested the idea of explaining the sameness of electricity with lightning. A paper upon this subject, which he wrote for Mr. Kinnersly, was read before the members of the Royal Society, and excited a hearty laugh. But it was the lot of this neglected theory to be generally adopted by philosophers, and to bid fair to endure for ages.

8. It was in the same year, that Franklin started the plan of proving the truth of his doctrine, by actually drawing down the lightning, by means of sharp-pointed iron rods raised high into the clouds. It was not until the summer of 1752, that he was enabled to complete his grand discovery by actual experiment.

9. The plan which he had first proposed was, to erect a box on some high tower, or other elevated place, from which should rise a pointed iron rod. He thought that electrified clouds, passing over it, would impart a portion of their electricity, which would be made evident by presenting a key or the knuckle to it. There was at this time, in Philadelphia, no opportunity of trying an experiment of the kind. But while Franklin was waiting for the erection of a spire, it occurred to him that he might have a more ready access to the clouds by means of a common kite.

10. He prepared a kite by fastening two cross sticks to a silk handkerchief, which would not suffer from the rain so much as paper. To the upright stick he affixed an iron point. The string was, as usual, of hemp, excepting the lower end, which was made of silk, because this substance does not give a free passage to the electricity.

11. With this kite, on the appearance of a thunder storm, he went out into the commons with his son, to whom alone he had communicated his intentions. He placed himself under a shed to avoid the rain; his kite was raised – a thunder cloud passed over it, but no sign of electricity appeared. The experiment had almost been given up in despair, when he perceived, in the loose fibres of the string, evident appearances of electricity. By continued observation the fact was most clearly proved; and the honor of establishing the sameness of electricity and lightning was won by Franklin.

12. The letters which Franklin had sent to Mr. Collinson were published by that gentleman in a separate volume, under the title of "New Experiments and Observations on Electricity, made at Philadelphia, in America." They were read with great eagerness, and soon translated into different languages. A very incorrect French translation fell into the hands of the celebrated Buffon, who was much pleased with it, and performed the experiments with success. A more correct translation was undertaken at his request, and contributed much towards spreading a knowledge of Franklin's principles in France. His experiments were repeated by most of the distinguished philosophers throughout Europe.

13. By these experiments, the truth of Franklin's doctrine was established in the firmest manner. When it could no longer be doubted, some men were anxious to take away from its merit. It was considered at that time rather mortifying to the European philosophers, to admit that an American could make important discoveries which had escaped their notice.

14. The Abbé Nollet, preceptor in natural philosophy to the royal family of France, was exceedingly offended at the publication of Franklin's letters. He had himself written about electricity, and could not at first believe that such a work had really come from America. He said it must have been composed by his enemies in Paris, to oppose his system. Afterwards, having been assured that there really existed such a person as Franklin at Philadelphia, he published a volume of letters, in defence of his own ideas upon the subject, and denying the propositions of the American philosopher.

15. Franklin thought at one time of writing a letter in reply to the abbé, and actually began one. But on considering that any one might repeat his experiments, and ascertain for himself whether or not they were true, he concluded to let his papers shift for themselves; believing it was better to spend what time he could spare in making new experiments than in disputing about those already made.

16. The event gave him no cause to repent of his silence. His friend, Monsieur Le Roy, of the Royal Academy of Sciences, took up his cause, and refuted the abbé. Franklin's volume was translated into the Italian, German and Latin languages; and the doctrine it contained was, by degrees, generally adopted by the philosophers of Europe, in preference to that of Nollet.

17. What gave his book the more sudden and general celebrity was the success of one of its proposed experiments, made at Marly, for drawing lightning from the clouds. This engaged the public attention every where. The "Philadelphia experiments," as they were called, were performed before the king and court, and all the curious of Paris flocked to see them.

18. Dr. Wright, an English physician, was at Paris when they were the talk and wonder of the day. He wrote to a member of the Royal Society an account of the high esteem in which the experiments of Franklin were held by learned men abroad and of their surprise that his writings had been so little noticed in England. The society, on this, resumed the consideration of the letters that had been read to them, and a summary account of their doctrines was drawn up and published among their philosophical essays and transactions.

19. To make Franklin some amends for the slight with which they had before treated him, the society chose him a member, without his having made the usual application. They also presented him with the gold medal of Sir Godfrey Copley for the year 1753, the delivery of which was accompanied by a very complimentary speech from the president, Lord Macclesfield.

CHAPTER XII

Appointed Postmaster-General. Journey to New England. Receives Degrees from two Colleges. Story of the Visit to his Mother.

1. Having been some time employed by the postmaster-general of America in regulating the several offices, and bringing the officers to account, upon his death, in 1753, Franklin was appointed, jointly with another gentleman, to succeed him. The American office had before this time never paid any thing to that of Great Britain; and the new postmasters were to have six hundred pounds between them, if they could make that sum out of the profits of the office.

2. To do this, a variety of improvements were necessary, some of which were at first very expensive; so that, for the first four years, the office became more than nine hundred pounds in debt to them. Afterwards they began to be repaid, and before Franklin was displaced, they had brought it to yield three times as much clear profit to the crown, as the post-office of Ireland. After Franklin's dismission, they never received a farthing from it.

3. The business of the post-office occasioned his taking a journey to New England, where the College of Cambridge presented him with the degree of Master of Arts. Yale College, in Connecticut, had before paid him a similar compliment. Thus, without studying in any college, he came to partake of their honors. They were conferred in consideration of his discoveries and improvements in natural philosophy.

4. It was either during this or his former journey that the story of the visit to his mother originated. He had been some years absent from his native city, and was at that period of life when the greatest and most rapid alteration is made in the human appearance. Franklin was sensible that his person had been so much changed that his mother would not know him, unless there were some instinct to point out, at a single glance, the child to its parent.

5. To discover the existence of this instinct by actual experiment, Franklin determined to introduce himself to his mother as a stranger, and to watch narrowly for the moment in which she should discover her son. On the afternoon of a sullen cold day, in the month of January, he knocked at his mother's door, and asked to speak with Mrs. Franklin. He found the old lady knitting before the parlor fire, introduced himself, by observing that he had been informed she entertained travellers, and requested a night's lodging.

6. She eyed him with coldness, and assured him that he had been misinformed – that she did not keep a tavern; though, to oblige some members of the legislature, she took a number of them into her family during the session; and at that time had four members of the council and six of the house of representatives who boarded with her. She added that all her beds were full, and went on knitting with a great deal of vehemence.

7. Franklin wrapped his coat around him, pretending to shiver with the cold, and observing that it was very chilly weather. It was, of course, nothing more than civil for the old lady to ask him to stop and warm himself. She pointed to a chair, and he drew himself up to the fire.

8. The entrance of her boarders prevented any further conversation. Coffee was soon served, and the stranger partook with the rest of the family. To the coffee, according to the custom of the times, succeeded a plate of apples, pipes, and a paper of tobacco. A pleasant circle of smokers was then formed about the fire. Agreeable conversation followed. Jokes were cracked, stories told, and Franklin was so sensible and entertaining as to attract the attention of the whole company.

9. In this manner the moments passed pleasantly and swiftly along, and it was eight o'clock before any of them expected it. This was the hour of supper, and Mrs. Franklin was always as punctual as the clock. Busied with family affairs, she supposed the stranger had quitted the house immediately after coffee. Imagine her surprise, when she saw him, with the utmost coolness and impudence, taking his seat with the family at the supper table!

10. Immediately after supper, she called an elderly gentleman, a member of the council, with whom she was in the habit of consulting, into another room; complained of the rudeness of the stranger, told the manner of his coming into the house, observed that he appeared like a foreigner, and she thought had something about him very suspicious. The old gentleman assured her that she need not be under any alarm, that the stranger was a man of education and agreeable manners, and was, probably, unaware of the lateness of the hour. He added, that it would be well to call him aside, and repeat to him that she was unable to give him lodgings.

11. She accordingly sent her maid to him, and then repeated the account of their situation, observed that it grew late, and gently hinted that he would do well to seek out other accommodations. The stranger replied that he should be very sorry to put her to any inconvenience, and would retire after smoking one more pipe with her boarders. He returned to the company, filled his pipe, and began talking as pleasantly and forcibly as ever. He recounted the hardships, and praised the piety and wisdom of their ancestors.

12. A gentleman present mentioned the subject of the day's debate in the house of representatives. A bill had been introduced to extend the powers of the royal governor. The stranger immediately entered upon the subject, supported the rights of the colonies with many arguments and much eloquence, and showed a great familiarity with the names of influential members of the house in the time of Governor Dudley.

13. The conversation was so animated and interesting that the clock struck eleven, unnoticed by the delighted circle. The patience of Mrs. Franklin was by this time completely exhausted. She now entered the room, and, before the whole company, addressed the stranger with much anger; told him plainly that she thought herself imposed upon; that she was a lone woman, but had friends who would protect her; and concluded by telling him to leave the house. Franklin made a slight apology, put on his great coat and hat, took a polite leave of the company, and approached the street door, lighted by the maid, and attended by the mistress.

14. While the company had been enjoying themselves within, a most tremendous snow storm had filled the streets, knee-deep; and no sooner had the maid lifted the latch, than a roaring wind forced open the door, put out the light, and almost filled the entry with drifted snow and hail. As soon as the candle was relighted, the stranger cast a mournful look on the lady of the mansion, and said – "My dear madam, if you turn me out of your house in this dreadful storm, I am a stranger in the town, and shall certainly perish in the streets. You look like a charitable lady; I should not think you could refuse shelter to a dog on such a night."

15. "Don't tell me of charity," said the offended matron; "charity begins at home. It is your own fault that you staid so long. In short, sir, I do not like your looks, or your conduct in thus forcing yourself upon my family, and I fear you have some bad designs."

16. The good lady had grown so angry as to raise her voice much above its ordinary pitch, and the noise drew all the company into the entry. They did not agree with Mrs. Franklin in respect to the stranger at all. He seemed to them to be a very honest, clever-looking fellow, and so far from wishing to turn him out of the house, there was not one of them but would have been glad to have him for a fellow-boarder. They thought him very sensible and pleasant, and could not account for their landlady's aversion.

17. At length, by their united interference, the stranger was permitted to remain in the house. There was no bed or part of a bed unoccupied, and he was obliged to sleep all night in an easy chair, before the parlor fire. Although her boarders appeared to have perfect confidence in his honesty, it was not so with Mrs. Franklin. She very carefully collected her silver spoons, pepper box and porringer from her closet, and, after securing the parlor door, by sticking a fork over the latch, carried them to her chamber. She charged the negro man to sleep with his clothes on – to take the great cleaver to bed with him, and to wake up and seize the vagrant at the first noise he made in plundering the house. The good lady then retired to bed with her maid, whom she compelled to sleep in the same room.

18. After a very restless night, Mrs. Franklin rose before the sun. She called her domestics, proceeded with them in a body to unfasten the parlor door. To her great astonishment, she found her guest quietly sleeping in his chair. She now began to feel sorry for her suspicions. Awaking him with a cheerful good morning, she inquired how he had rested, and invited him to partake of her breakfast, which was always served before that of the boarders.

19. "Pray, sir," said the old lady, as they were sipping their chocolate at the breakfast table, "as you appear to be a stranger here, to what distant country do you belong?"

20. Franklin put a little more sugar into his chocolate, and, helping himself to a slice of toast, replied, that he belonged to the city of Philadelphia. At the mention of this word, the old lady, for the first time, exhibited emotion. "Philadelphia?" said she – "if you live in Philadelphia, perhaps you know our Ben?"

21. "Who, madam?" replied Franklin, in the same cool and undisturbed manner that he had put on ever since he entered the house. "Why, Ben Franklin," said the mother; "my Ben – oh! he is the dearest child that ever blessed a mother!"

22. "What," said the stranger, "is Ben Franklin, the printer, your son? Why, he is my most intimate friend: he and I lodge in the same room." "O! Heaven forgive me!" exclaimed the old lady; "and have I suffered an acquaintance of my Benny to sleep on this hard chair, while I myself rested on a good bed!"

23. We can well imagine that the mother was very much astonished when she found that it was not an acquaintance of her son, but her son himself, whose countenance and person had been so much changed, that she had even been on the point of turning him out of doors! She was delighted to embrace him once more before she died, and was quite pleased that the members of the council had found him so agreeable a fellow as to insist that he should remain all night in the house.
