The shrinking that a mahogany box, given to him in England, underwent, when subjected to the atmospheric conditions of America, suggested a hygrometer to him which Nairne afterwards constructed in accordance with his plans.[55]
His mind seems to have had no torpid moments, except, perhaps, when some Congressional orator was speaking. When, in early life, he had nothing else better to do, he would address himself to making magic squares and circles as intricate as Rosamond's walk. "He took it into his head," James Logan wrote to Collinson, "to think of magical squares, in which he outdid Frenicle himself, who published above eighty pages in folio on that subject alone." Not willing to be outdone even by Stifelius, Franklin drew a square of such extraordinary numerical properties that not only did the numbers on all the rows and diagonals on its face total 2056, but the sum of the numbers on every group of 16 smaller squares on its face, when revealed through a hole in a piece of paper, moved backwards and forwards over its face, equalled precisely 2056 too. He likewise drew a
magick circle, consisting of 8 concentric circles, and 8 radial rows, filled with a series of numbers, from 12 to 75, inclusive, so disposed as that the numbers of each circle or each radial row, being added to the central number 12, they made exactly 360, the number of degrees in a circle; and this circle had, moreover, all the properties of the square of 8.
Both of these conceits were duly forwarded to Collinson and, with regard to the square of 16, Franklin wrote to him playfully that he made no question but that he would readily allow that it was the most magically magical of any magic square ever made by any magician. From the terms of this letter, it is plain that the practical intellect of Franklin was a little ashamed of these feats as but difficiles nugæ, but his misgivings were somewhat soothed by the suggestion of Logan that they might not be altogether useless if they produced by practice an habitual readiness and exactness in mathematical disquisitions.
Hardly more profitable than the magic squares but indicative, too, of the same mental initiative, was the scheme formed by Franklin for a new alphabet and a reformed mode of spelling. In the new alphabet, the first effort was to arrange the letters in what was supposed to be a more natural order than that of the old alphabet by beginning with the simple sounds framed by the breath with no or very little help from the tongue, teeth and lips, and proceeding gradually forward from sounds, produced at the back of the mouth, to the sound produced by closing the lips, that is m. The c of the old alphabet was omitted, k being left to supply its hard sound, and s its soft, and k being also left to supply the place of q, and with an s added, the place of x. W as well as q and x was also dismissed from service, the vowel u, sounded as oo, being relied upon to perform its function. Y also went by the board, i taking its place, where used singly, and two vowels, where used as a diphthong. J was superseded by an entirely new symbol, shaped something like a small h, and sounded as ish, when used singly, but subserving various other offices, when conjoined with d, t and z. As a whole, the new alphabet was so systematized that the sound of any letter, vowel or consonant was always the same, wherever it occurred, or whatever its alphabetical collocation. Nor did the new alphabet contain any silent letters, or fail to provide a letter for every distinct sound in the language. The difference between short and long vowels was compassed by a single vowel where short, and a double one, where long. For illustration, "mend" remained "mend" and "did," "did," but "remained" reappeared as "remeened," and "deed" as "diid." Typographical obstacles prevent us from bringing to the eye of the reader a specimen of the reformed alphabet and spelling as they looked on a printed page. They, of course, issued from the mind of Franklin as stillborn as his reformed Episcopal Prayer Book. His only proselytes appear to have been Polly, who even wrote a letter to him in the strange forms, and his loving sister, Jane, who was delighted to have another language with which to express her affection for him. Our world is one in which some things are made but others make themselves, and, however arbitrary their character, will not allow themselves to be made over, even at the behest of such merciless rationalism as that of Franklin.
In the latter part of Franklin's life, Noah Webster, the lexicographer, also formed a scheme for the reform of the alphabet, and Franklin had the pleasure of writing to him, "Our Ideas are so nearly similar, that I make no doubt of our easily agreeing on the Plan." Several years later, Webster, in his Dissertations on the English Language, stated that Franklin had compiled a dictionary, based upon his own reformatory system, and procured the types for printing it, but, finding himself too old to prosecute his design, had offered both manuscript and types to him. "Whether this project, so deeply interesting to this country," Webster said, "will ever be effected; or whether it will be defeated by insolence and prejudice, remains for my countrymen to determine."
Another thing upon which the ingenuity of Franklin was brought to bear, as the reader has already been told, was the Armonica. In his letter to Beccaria, extolling its merits, he describes it with a wealth of detail, not only thoroughly in keeping with his knack for mechanics, but showing that to music as to everything else, that won the favor of his intellect, he brought the ken of a man of science. The letter concludes with a dulcet compliment, which harmonizes well with its subject: "In honour of your musical language (the Italian), I have borrowed from it the name of this instrument, calling it the Armonica." In one of his papers, he drew up instructions for the proper use of the instrument which nothing but the most intimate familiarity with its operation could have rendered possible.
Admiration has often been expended upon the acuteness with which Franklin, in a letter to Lord Kames, accounted for the pleasure afforded by the old Scotch tunes, as compared with the pleasure afforded by the difficult music of his day, which, he said, was of the same nature as that awakened by the feats of tumblers and rope-dancers. The reason was this. The old Scotch melodies were composed by the minstrels of former days, to be played on the harp, accompanied by the voice. The harp was strung with wire (which gives a sound of long continuance) and had no contrivance like that in the modern harpsichord, by which the sound of the preceding note could be stopped, the moment a succeeding note began. To avoid actual discord, it was therefore necessary that the succeeding emphatic note should be a chord with the preceding, as their sounds must exist at the same time. Hence arose that beauty in those tones that had so long pleased, and would please forever, though men scarce knew why.
The most useful invention of Franklin was what came to be known as the Franklin stove. With modifications, it is still in use, and the essay written on it by Franklin, entitled An Account of the New-invented Pennsylvanian Fireplaces, is one of the best illustrations of the capacity of his scientific genius to adapt itself to the hardest and barest offices that human comfort and convenience could impose upon it with a nicety and accuracy of trained insight and touch worthy of the cleverest journeyman, a command of scientific principles to be expected only of a professional student, and a gift of clear, lively expression which reminds us of the remark of Stella that Dean Swift could write agreeably even about a broomstick. The principle upon which the Franklin stove was constructed was that of making the heat from its open fireplace, after first ascending to its top, descend in such a manner at its back, before passing off into the chimney, as to diffuse by radiation through the room, in which it stood, a large part of its warmth. The essay enumerates the different methods of heating rooms then in use: the great, open, smoky chimney-place, that the unremitting labor of one man could scarce keep supplied with fuel, and that gave out little more heat for human warmth than a fire outdoors; this chimney-place reduced to a smaller size with jambs, and free, to a great extent from the reproach of smokiness, yet, with its contraction setting up strong currents of whistling and howling air, which reminded Franklin of the Spanish proverb,
"If the Wind blows on you thro' a Hole,
Make your Will, and take Care of your Soul";
