The library, once established, grew apace. From time to time, huge folios and quartos were added to it by purchase or donation, from which nobody profited more than Franklin himself with his insatiable avidity for knowledge. The first purchase of books for it was made by Peter Collinson of London, who threw in with the purchase as presents from himself Newton's Principia and the Gardener's Dictionary, and continued for thirty years to act as the purchasing agent of the institution, accompanying each additional purchase with additional presents from himself. Evidence is not wanting that the first arrival of books was awaited with eager expectancy. Among Franklin's memoranda with regard to the Junto we find the following: "When the books of the library come, every member shall undertake some author, that he may not be without observations to communicate." When the books finally came, they were placed in the assembly room of the Junto; a librarian was selected, and the library was thrown open once a week for the distribution of books. The second year Franklin himself acted as librarian, and for printing a catalogue of the first books shortly after their arrival, and for other printing services, he was exempted from the payment of his annual ten shillings for two years.
Among the numerous donations of money, books and curiosities made to the library, were gifts of books and electrical apparatus by Thomas Penn, and the gift of an electrical tube, with directions for its use, by Peter Collinson, which proved of incalculable value to science in the hands of Franklin who promptly turned it to experimental purposes. When Peter Kalm, the Swedish naturalist, was in Philadelphia in 1748, "many little libraries," organized on the same plan as the original library, had sprung from it. Non-subscribers were then allowed to take books out of it, subject to pledges of indemnity sufficient to cover their value, and to the payment for the use of a folio of eight pence a week, for the use of a quarto of six pence, and for the use of any other book of four pence. Kalm, as a distinguished stranger, was allowed the use of any book in the collection free of charge. In 1764, the shares of the library company were worth nearly twenty pounds, and its collections were then believed to have a value of seventeen hundred pounds. In 1785, the number of volumes was 5487; in 1807, 14,457; in 1861, 70,000; and in 1912, 237,677. After overflowing more contracted quarters, the contents of the library have finally found a home in a handsome building at the northwest corner of Locust and Juniper Streets and in the Ridgway Branch Building at the corner of Broad and Christian Streets. But, never, it is safe to say, will this library, enlarged and efficiently administered as it is, perform such an invaluable service as it did in its earlier years. "This," Franklin declares in the Autobiography, "was the mother of all the North American subscription libraries, now so numerous. It is become a great thing itself, and continually increasing. These libraries have improved the general conversation of the Americans, made the common tradesmen and farmers as intelligent as most gentlemen from other countries, and perhaps have contributed in some degree to the stand so generally made throughout the colonies in defence of their privileges."
Franklin next turned his attention to the reform of the city watch. Under the existing system, it was supervised by the different constables of the different wards of Philadelphia in turn. The Dogberry in charge would warn a number of householders to attend him for the night. Such householders as desired to be wholly exempt from the service could secure exemption by paying him six shillings a year, which was supposed to be expended by him in hiring substitutes, but the fund accumulated in this way was much more than was necessary for the purpose and rendered the constableship a position of profit. Often the ragamuffins gathered up by a constable as his aids were quite willing to act as such for no reward except a little drink. The consequence was that his underlings were for the most part tippling when they should have been moving around on their beats. Altogether, they seem to have been men who would not have been slow to heed the older Dogberry's advice to his watchmen that, if one of them bid a vagrom man stand, and he did not stand, to take no note of him, but to let him go, and presently call the rest of the watch together and thank God that he was rid of a knave.
To this situation Franklin addressed himself by writing a paper for the Junto, not only setting forth the abuses of the existing system but insisting upon its injustice in imposing the same six shilling tax upon a poor widow, whose whole property to be guarded by the watch did not perhaps exceed the value of fifty pounds, as upon the wealthiest merchant who had thousands of pounds' worth of goods in his stores. His proposal was the creation of a permanent paid police to be maintained by an equal, proportional property tax. The idea was duly approved by the Junto, and communicated to its affiliated clubs, as if it had arisen in each of them, and, though it was not immediately carried into execution, yet the popular agitation, which ensued over it, paved the way for a law providing for it which was enacted a few years afterwards, when the Junto and the other clubs had acquired more popular influence.
About the same time, the same indefatigable propagandist wrote for the Junto a paper, which was subsequently published, on the different accidents and defaults by which houses were set on fire, with warnings against them, and suggestions as to how they might be averted. There was much public talk about it, and a company of thirty persons was soon formed, under the name of the Union Fire Company, for the purpose of more effectively extinguishing fires, and removing and protecting goods endangered by them. Under its articles of agreement, every member was obliged to keep always in good order, and fit for use, a certain number of leather buckets, with strong bags and baskets for transporting goods, which were to be brought to every fire; and it was further agreed that the members of the company were to meet once a month and spend a social evening together in the discussion and interchange of such useful ideas as occurred to them upon the subject of fires. The formation of this company led to the formation of one company after another until the associations became so numerous as to include most of the inhabitants of Philadelphia who were men of property. It was still flourishing more than fifty years after its establishment, when its history was narrated in the Autobiography, and Franklin and one other person, a year older than himself, were the only survivors of its original members. The small fines, paid by its members as penalties for absence from its monthly meetings, had been used to such advantage in the purchase of fire-engines, ladders, fire-hooks and other useful implements for the different companies that Franklin then questioned whether there was a city in the world better provided than Philadelphia with the means for repressing incipient conflagrations. Indeed, he said, since the establishment of these companies, the city had never lost by fire more than one or two houses at a time; and often flames were extinguished before the house they threatened had been half consumed.
"Ideas will string themselves like Ropes of Onions," Franklin once declared. This was certainly true of the plans which his public spirit devised for the improvement of Philadelphia. The next thing to which his hand was turned was the creation of an academy. In 1743, he drew up a proposal for one, but, being disappointed in his efforts to persuade the Reverend Mr. Peters to act as its head, he let the project lie dormant for a time. While it remained so, remembering Poor Richard's maxim that leisure is time for doing something useful, he passed to the organization of a system of military defenses for the Province and the founding of a Philosophical Society. Of the former task we shall speak hereafter. The latter was initiated by a circular letter from him to his various learned friends in the Northern Colonies, proposing the formation of a society for the purpose of promoting a commerce of speculation, discovery and experimentation between its members with regard to scientific interests of every sort. A correspondence with the Royal Society of London and the Dublin Society and "all philosophical experiments that let light into the nature of things, tend to increase the power of man over matter, and multiply the conveniences or pleasures of life" were among the things held out in the proposal. Colonial America was far more favorable to practical activity than to philosophical investigation, but the society, nevertheless, performed an office of no little usefulness. When Franklin built a new wing to his residence in Philadelphia, after his return from Paris, he provided a large apartment
