uniformly refused to except of any compensation. During this time, he communicated to the directors every information relative to improvements and discoveries in the arts, agriculture and philosophy.

The beneficial influence of this institution was soon evident. The terms of subscription to it were so mo. g. Jerate, that it was accessible to every one. Its advan.

tages were not confined to the opulent. The citizens in the middle and lower walks of life were equally partakers of them. Hence a degree of information

was extended amongst all classes of people. The En example was soon followed. Libraries were estab

lished in various places, and they are now become very numerous in the United States, and particularly in Pennsylvania. It is to be hoped that they will be still more widely extended, and that information will be every where increased. This will be the best security for maintaining our liberties. A nation of wellinformed men, who have been taught to know and prize the rights which God has given them, cannot be enslaved. It is in the regions of ignorance that tyranny reigns. It flies before the light of science. Let the citizens of America, then, encourage institutions calculated to diffuse knowledge amongst people ; and

amongst these, public libraries are not the least im. te portant.

In 1732, Franklin began to publish Poor Richard's Almanac. This was remarkable for the numerous and valuable concise maxims wisich it contained, all tending to exhort to industry and frugalityit was continued for many years.

In the almanac for the last year, all the maxiins were collected in an address to the reader, entitled, “ The Way to Wealth.” This has been translated into various languages, and inBerted in different publications. It has also been

printed on a large sheet, and may be seen-framed in ► many houses in this city. This address contains,

perhaps, the best practical system of economy that ever has appeared. It was written in a manner intelligible to every one, and which cannot fail of convincing every reader of the justice and propriety of the remarks and advice which it contains. The demand for this almanac was so great, that ten thousand

have been sold in one year; which must be consi. dered as a very large number, especially when we reflect, that this country was, at that time, but thinly peopled. It cannot be doubted that the salutary maxims contained in these almanacs must bave made a favourable impression upon many of the readers of them.

It was 'not long before Frånklin entered upon his Fre political career. In the year 1736, he was appointed clerk to the general assembly of Pennsylvania ; and was re-elected by succeeding assemblies for several years, until he was chosen a representative for the city of Philadelphia.

Bradford was possessed of some advantages over Franklin, by being post-master, thereby having an opportunity of circulating his paper more extensively, and thus rendering it a better vehicle for advertisements, &c. Franklin, in his turn, enjoyed these advantages, by being appointed post-master of Philadelphia, in 1737. Bradford, while in office, had acted ungenerously toward Franklin, preventing, as much as possible, the circulation of his paper. He had now an opportunity of retaliating: but his nobleness of soul prevented him from making use of it.

The police of Philadelphia had early appointed watchmen, whose duty it was to guard the citizens against the midnight robber, and to give an immediate alarm in case of fire. This duty is, perhaps, one of the most important that can be committed to any set of men. The regulations, however, were not sufficiently strict. Franklin saw the dangers arising from this cause, and suggested an alteration, so as to oblige the guardians of the night to be more watchful over the lives and property of the citizens. The propriety of this was immediately perceived, and a reform was effected.

There is nothing more dangerous to growing cities than fires. Other causes operate slowly, and almost imperceptibly : but these, in a moment, render abortive the labours of ages. On this account there should be, in all cities, "ample provisions to prevent fires from spreading. Franklin early saw the necessity of these ; and, about the year 1738, formed the first fire com

pany in this city. This example was soon followed by others; and there are now numerous fire compa. pies in the city and liberties. To these may be atiributed, in a great degree, the activity in extinguishing fires, for which the citizens of Philadelphia are distinguished, and the inconsiderable damage which this city has sustained from this cause. Some time after, Franklin suggested the plan of an association for in suring houses from losses by fire, which was adopted; and the association continues to this day. The advantages experienced from it have been great.

From the first establishment of Pennsylvania, a spirit of dispute appears to have prevailed amongst its inhabitants. During the life-time of William Penn, the constitution had been three times altered. After this period, the history of Pennsylvania is little else than a recital of the quarrels between the proprietaries, or their governors, and the Assembly. The proprietaries contended for the right of exempting their lands from taxes"; to which the Assembly would by no means consent." This subject of dispute interfered in almost every question, and prevented the most salutary laws from being enacted. This, at times, subjected the people to great inconveniences. In the year 1744, during a war between France and Great Britain, some French and Indians had made inroads upon the frontier inhabitants of the province, who were unprovided for such an attack. It became necessary that the citizens should arm for their defence. Governor Thomas recommended to the Assembly, who were then sitting, to pass a militia law. To this they would agree, only upon condition that he should give his assent to certain laws, which appeared to them calculated to promote the interests of the people. As he thought these laws would be injurious to the proprietaries, he refused his assent to them; and the Assembly broke up without passing a militia law. The situation of the province was, at this time, truly alarming; exposed to the continual inroad of an enemy, destitute of every means of defence. At this crisis, Franklin stepped forth, and proposed to a meeting of the citizens of Philadelphia, a plan of a voluntary association for the defence of the province.

This was approved of, and signed by twelve hundred persons immediately. Copies were instantly circu. lated throughout the province; and, in a short time, the number of signers amounted to ten thousand. Franklin was chosen colonel of the Philadelphia regiinent; but he did not think proper to accept of the honour.

Pursuits of a different nature now occupied the greatest part of his attention for some years." He engaged in a course of electrical experiments, with all The ardour and i hirst for discovery which characterized the philosophers of that day. Of all the branches of experimental philosophy, electricity had been least explored. The attractive power of amber is mentioned by Theophrastus and Pliny, and from them, by la. ter naturalists. In the year 1600, Gilbert, an English physician, enlarged, considerably, the catalogue of substances which have the property of attracting, light bodies Boyle, Otto Guericke, a burgomaster of Magdeburg, celebrated as the inventor of the airpump, Dr Wall, and Sir Isaac Newton, added soine facts. Guericke first observed the repulsive power of electricity, and the light and noise produced by it. In 1709, Hawkesbec communicated some important observations and experiments to the world. For several years, electricity was entirely neglected, until Mr Grey applied himself to it, in 1723, with great assia duity. He and his friend, Mr. Wheeler, made a great variety of experiments; in which they demostrated, that electricity may be communicated from one body to another even without being in contact, and in this way may be conducted to a great distance. Mr. Grey afterwards found, that, by suspending rods of iron by silk or hair lines, and bringing an excited tube under them, sparks might be drawn, and a light perceived at the extremities in the dark. M Du Faye, inten. dant of the French king's gardens, made a nuniber of experiments, which added not a little to the science. Ile made the discovery of two kinds of electricity, which he called vitreous, and resinous ; the former produced by rubbing glass, the latter from excited sulphur, sealing wax, &c. But this idea he afterwards gave up as erroneous. Between the years 1739

and 1742, Desauguliers made a number of experiments, but added little of importance. He first used the terms conductors and electrics per se. In 1742, several ingenious Germans engaged in this subject; of these the principal were, professor Boze, of Wittemberg, professor Winkles, of Leipsic, Gordon, a Scotch Benedictine monk, professor of philosophy at Erfurt, and Dr. Ludolf, of Berlin. The result of their researches astonished the philosophers of Europe. Their apparatus was large, and by means of it they were enabled to collect large quantities of the electric fluid, and thus to produce phenomena which had been hitherto unobserved. They killed small birds, and set spirits on fire. Their experiments excited the curiosity of other philosophers. Collinson, about the year 1745, sent to the Library Company of Philadelphia an account of these experiments, together with a tube and directions how to use it. Franklin, with some of his friends, immediately engaged in a course of experiments; the result of which is well known. He was enabled to make a number of important discoveries, and to propose theories to account for various phenomena, which have been universally adopted, and which' bid fair to endure for ages. His observations he communicated, in a series of letters, to his friend Collinson; the first of which is dated March 28, 1747. In these he shows the power of points in drawing and throwing off the electrical matter, which had hitherto escaped the notice of electricians. He also made the grand discovery of a plus and minus, or of a positive and negative state of electricity. We give him the honour of this, without hesitation; although the English have claimed it for their countryman, Dr. Watson. Watson's paper is dated January 21, 1748 ; Franklin's, July 11, 1747; several months prior.. Shortly after, Franklin, fronı his principles of the plus and minus state, explained, in a satisiactory manner, the phenomena of the Leyden phial, first observed by Mr. Cuneus, or by professor Muschenbroeck, of Leyden, which had much perplexed philosophers. He showed clearly, that the bottle, when charged, contained no more electricity than before, but that as much was taken from one
