We acted in concert to supply Braddock's army with provisions; and when the shocking news arrived of his defeat, the governor sent in haste for me, to consult with him on measures for preventing the desertion of the back counties. I forget now the advice I gave; but I think it was that Dunbar should be written to, and prevailed with, if possible, to post his troops on the frontiers for their protection, till by reinforcements from the colonies, he might be able to proceed on the expedition. And, after my return from the frontier, he would have had me undertake the conduct of such an expedition with provincial troops, for the reduction of Fort Duquesne, Dunbar and bis men being otherwise employed; and he proposed to commission me as general. I had not so good an opinion of my military abilities as he professed to have, and I believe his professions must have exceeded his real sentiments; but probably he might think that my popularity would facilitate the raising of the men, and my influence in Assembly the grant of money to pay them, and that, perhaps, without taxing the proprietary estate. Finding me not so forward to engage as he expected, the project was dropt, and he soon after left the government, being superseded by Captain Denny.
In 1746, being at Boston, I met there with a Dr. Spence, who was lately arrived from Scotland, and showed me some electric experiments. They were imperfectly performed, as he was not very expert, but, being on a subject quite new to me, they equally surprised and pleased me. Soon after my return to Philadelphia, our library company received from Mr. P. Collinson, Fellow of the Royal Society of London, a present of a glass tube, with some account of the use of it in making such experiments. I eagerly seized the opportunity of repeating what I had seen at Boston; and, by much practice, acquired great readiness in performing those, also, which we had an account of from England, adding a number of new ones. I say much practice, for my house was continually full, for some time, with people who came to see these new wonders.
To divide a little this incumbrance among my friends, I caused a number of similar tubes to be blown at our glass-house, with which they furnished themselves, so that we had at length several performers. Among these, the principal was Mr. Kinnersley, an ingenious neighbor, who, being out of business, I encouraged to undertake showing the experiments for money, and drew up for him two lectures, in which the experiments were ranged in such order and accompanied with such explanations in such method as that the foregoing should assist in comprehending the following. He procured an elegant apparatus for the purpose, in which all the little machines that I had roughly made for myself were nicely formed by instrument-makers. His lectures were well attended, and gave great satisfaction; and after some time he went thro' the colonies, exhibiting them in every capital town, and picked up some money. In the West India Islands, indeed, it was with difficulty the experiments could be made, from the general moisture of the air.
