"Make a small Cross of two light Strips of Cedar, the Arms so long as to reach to the four Corners of a large thin Silk Handkerchief when extended; tie the Corners of the Handkerchief to the Extremities of the Cross, so you have the Body of a Kite; which being properly accommodated with a Tail, Loop and String, will rise in the Air, like those made of Paper; but this being of Silk is fitter to bear the Wet and Wind of a Thunder Gust without tearing. To the Top of the upright Stick of the Cross is to be fixed a very sharp pointed Wire, rising a Foot or more above the Wood. To the End of the Twine, next the Hand, is to be tied a silk Ribbon, and where the Twine and the silk join, a Key may be fastened. This Kite is to be raised when a Thunder Gust appears to be coming on, and the Person who holds the String must stand within a Door, or Window, or under some Cover, so that the Silk Ribbon may not be wet; and Care must be taken that the Twine does not touch the Frame of the Door or Window. As soon as any of the Thunder Clouds come over the Kite, the pointed Wire will draw the Electric Fire from them, and the Kite, with all the Twine, will be electrified, and the loose Filaments of the Twine will stand out every Way, and be attracted by an approaching Finger. And when the Rain has wet the Kite and Twine, so that it can conduct the Electric Fire freely, you will find it stream out plentifully from the Key on the Approach of your Knuckle. At this Key the Phial may be charg'd; and from Electric Fire thus obtain'd, Spirits may be kindled, and all the other Electric Experiments be perform'd, which are usually done by the Help of a rubbed Glass Globe or Tube; and thereby the Sameness of the Electric Matter with that of Lightning compleatly demonstrated."

“I am much obliged by the kind present you have made us of your edition of Vattel. It came to us in good season, when the circumstances of a rising state make it necessary frequently to consult The Law of Nations. Accordingly, that copy which I kept, (after depositing one in our own public library here, and sending the other to the college of Massachusetts Bay, as you directed,) has been continually in the hands of the members of our congress, now sitting, who are much pleased with your notes and preface, and have entertained a high and just esteem for their author.”

“[A] great Empire, like a great Cake, is most easily diminished at the Edges.”

“Can sweetening our tea, &c. with sugar, be a circumstance of such absolute necessity? Can the petty pleasure thence arising to the taste, compensate for so much misery produced among our fellow creatures, and such a constant butchery of the human species by this pestilential detestable traffic in the bodies and souls of men?—Pharisaical Britain! to pride thyself in setting free a single Slave that happens to land on thy coasts, while thy Merchants in all thy ports are encouraged by thy laws to continue a commerce whereby so many hundreds of thousands are dragged into a slavery that can scarce be said to end with their lives, since it is entailed on their posterity!”

“[Referring to private hospital funding alone:] That won't work, it will never be enough, good health care costs a lot of money, remembering 'the distant parts of this province' in which 'assistance cannot be procured, but at an expense that neither [the sick-poor] nor their townships can afford.' ... '[This] seems essential to the true spirit of Christianity, and should be extended to all in general, whether deserving or undeserving, as far as our power reaches.'”

“[T]he waters moved away from the North American Coast towards the coasts of Spain and Africa, whence they get again into the Power of the Trade Winds, and continue the Circulation. ...so long and so strong a Current as that of the Gulph Stream, thro' all the Latitudes of variable Winds, can only be accounted for, by its having a considerable Descent, and moving from Parts where the Water is higher, to Parts where it is lower.”

“How much more than is necessary do we spend in Sleep! forgetting that The sleeping Fox catches no Poultry,[Sept. 1743] and that there will be sleeping enough in the Grave,[Sept. 1741] as Poor Richard says.”
