borrower is a slave to the lender, and the debtor to the creditor; disdain the chain, preserve your freedom, and maintain your independency: be industrious and free; be frugal and free. At present perhaps you may think yourselves in thriving circumstances, and that you can bear a little extravagance without injury; but,

For age and want save while you may,
No morning sun lasts a whole day,'

as poor Richard says. Gain may be temporary and uncertain; but ever while you live, expense is constant and certain and it is easier to build two chimneys, than to keep one in fuel,' as poor Richard says. So Rather go to bed supperless than rise in debt.'

Get what you can, and what you get hold,

'Tis the stone that will turn all your lead into gold,'

as poor Richard says. And when you have got the philosopher's stone, sure you will no longer complain of bad times, or the difficulty of paying taxes.

"This doctrine, my friends, is reason and wisdom: but, after all, do not depend too much upon your own industry, and frugality, and prudence, though excellent things, for they may be blasted, without the blessing of heaven: and therefore ask that blessing humbly, and be not uncharitable to those that at present seem to want it, but comfort and help them. Remember, Job suffered, and was afterwards prosperous.

"And now, to conclude, Experience keeps a dear school; but fools will learn in no other, and scarce in that; for it is true, we may give advice, but we cannot give conduct,' as poor Richard says. However, remember this, "They that will not be counselled, cannot be helped,' as poor Richard says; and further, that 'If you will not hear Reason, she will surely rap your knuckles.

Thus the old gentleman ended his harangue. The people heard it, and approved the doctrine, and immediately prac tised the contrary, just as if it had been a common sermon ; for the auction opened, and they began to buy extravagantly, notwithstanding all his cautions, and their own fear of taxes. I found the good man had thoroughly studied my Almanacs, and digested all I had dropped on those topics, during the course of twenty-five years. The frequent mention he made of me, must have tired every one else; but my vanity was wonderfully delighted with it, though I was conscious that not a tenth part of the wisdom was my own which he

ascribed to me, but rather the gleanings that I had made of the sense of all ages and pations. However, I resolved to be the better for the echo of it; and though I had first deter mined to buy stuff for a new coat, I went away, resolved to wear my old one a little longer.

Reader, if thou wilt do the same, thy profit will be as great as mine.

I am, as ever, thine to serve thee,
RICHARD SAUNDERS.

Extract of a Letter from Dr Franklin to the celebrated Father Beccaria.

PERHAPS, it may be agreeable to you, as you live in a musical country, to have an account of the new instrument lately added here to the great number that charming science was before possessed of.-As it is an instrument that seems peculiarly adapted to Italian music, especially that of the soft and plaintive kind, I will endeavour to give you such a description of it, and the manner of constructing it, that you, or any of your friends, may be enabled to imitate it, if you incline so to do, without being at the expense and trouble of the many experiments I have made in endeavouring to bring it to its present perfection.

You have doubtless heard the sweet tone that is drawn from a drinking-glass, by passing a wet finger round its brim. One Mr Puckeridge, a gentleman from Ireland, was the first who thought of playing tunes, formed of these tones. He collected a number of glasses of different sizes, fixed them near each other on a table, and tuned them by putting into them water, more or less, as each note required. The tones were brought out by passing his fingers round their brims. He was unfortunately burned here, with his instrument, in a fire which consumed the house he lived in. Mr E. Delaval, a most ingenious member of our Royal Society, made one in imitation of it, with a better choice and form of glasses, which was the first I saw or heard. Being charmed with the sweetness of its tones, and the music he produced from it, I wished only to see the glasses disposed in a more convenient form, and brought together in a narrower compass, so as to admit of a greater number of tones, and all within

reach of the hand of a person sitting before the instrument, which I accomplished, after various intermediate trials, and less commodious forms, both of glasses and construction, in the following manner:

The glasses are blown as near as possible in the form of hemispheres, having each an open neck, or socket in the middle. The thickness of the glass near the brim, about the tenth of an inch, or hardly quite so much, but thicker as it comes nearer the neck, which in the largest glasses is about an inch deep, and an inch and half wide within ; these dimensions lessening as the glasses themselves diminish in size, except that the neck of the smallest ought not to be shorter than half an inch.-The largest glass is nine inches diameter, and the smallest three inches. Between these three are twenty-three different sizes, differing from each other a quarter of an inch in diameter.-To make a single instrument there should be at least six glasses blown of each size; and out of this number, one may probably pick thirty-seven glasses (which are sufficient for three octaves, with all the semi-tones) that will be each either the note one wants or a little sharper than that note, and all fitting so well into each other as to taper pretty regularly from the largest to the smallest. It is true there are not thirty-seven sizes, but it often happens that two of the same size differ a note or halfnote in tone, by reason of a difference in thickness, and these may be placed one in the other without sensibly hurting the regularity of the taper form.

The glasses being chosen, and every one having marked with a diamond the note you intend it for, they are to be tuned by diminishing the thickness of those that are too sharp. This is done by grinding them round from the neck towards the brim, the breadth of one or two inches, as may be required; often trying the glass by a well-tuned harpsichord. When you come nearer the matter, be careful to wipe the glass clean and dry before each trial, because the tone is somewhat flatter when the glass is wet, than it will be when dry; and grinding very little between each trial, you will thereby tune to great exactness. The more care is necessary in this, because if you go below your required tone, there is no sharpening it again but by grinding somewhat off the brim, which will afterwards require polishing, and thus increase the trouble.

The glasses being thus tuned, you are to be provided with a case for them, and a spindle on which they are to be fixed. My case is about three feet long, eleven inches every way, wide within at the biggest end, and five inches at the smallest

end; for it tapers all the way, to adapt it better to the conical figure of the set of glasses. This case opens in the middle of its height, and the upper part turns up by hinges fixed behind. The spindle which is of hard iron, lies horizontally from end to end of the box within, exactly in the middle, and is made to turn on brass gudgeons at each end, and tapering to a quarter of an inch at the smallest.-A square shank comes from its thickest end through the box, on which a shank-wheel is fixed by a screw. This wheel serves as a fly to make the motion equable, when the spindle, with the glasses, is turned by the foot like a spinning-wheel. My wheel is of mahogany, eighteen inches diameter, and pretty thick, so as to conceal near its circumference about twentyfive pounds of lead.-An ivory pin is fixed in the face of this wheel, and about four inches from the axis. Over the neck of this pin is put the loop of the string that comes up from the moveable step to give it motion. The case stands on a neat frame with four legs.

To fix the glasses on the spindle, a cork is first to be fitted in each neck pretty tight, and projecting a little without the neck, that the neck of one may not touch the inside of another when put together, for that would make a jarring. These corks are to be perforated with holes of different diameters, so as to suit that part of the spindle on which they are to be fixed. When a glass is put on, by holding it stiffly between both hands, while another turns the spindle, it may be gradually brought to its place, but care must be taken that the hole be not too small, lest in forcing it up the neck should split; nor too large, lest the glass not being firmly fixed should turn or move on the spindle, so as to touch and jar against its neighbouring glass. The glasses thus are placed one in another, the largest on the biggest end of the spindle, which is to the left hand; the neck of this glass is toward the wheel, and the next goes into it in the same position, only about half an inch of its brim appearing beyond the brim of the first; thus proceeding, every glass when fixed shews about an inch of its brim (or threequarters of an inch, or half an inch, as they grow smaller) beyond the brim of the glass that contains it; and it is from these exposed parts of each glass that the tone is drawn, by laying a finger upon one of them as the spindle and glasses

turn round.

My largest glass is G, a little below the reach of a common voice, and my highest G, including three complete octaves. To distinguish the glasses the more readily to the eye, I have painted the apparent parts of the glasses within

side, every semi-tone white, and the other notes of the octave with the seven prismatic colours, viz. C, red; D, orange; E, yellow; F, green; G, blue; A, indigo; B, purple; and C, red again so that glasses of the same colour (the white excepted) are always octaves to each other.

This instrument is played upon, by sitting before the middle of the set of glasses, as before the keys of a harpsichord, turning them with the foot, and wetting them now and then with a sponge and clean water, and quite free from all greasiness; a little fine chalk upon them is sometimes useful, to make them catch the glass and bring out the tone more readily. Both hands are used, by which means different parts are played together.-Observe, that the tones are the best drawn out when the glasses turn from the ends of the fingers, not when they turn to them.

The advantages of this instrument are, that its tones are incomparably sweet beyond those of any other; that they may be swelled and softened at pleasure, by stronger or weaker pressures of the finger, and continued to any length; and that the instrument being once well tuned, never again wants tuning.

In honour of your musical language, I have borrowed from it the name of this instrument, calling it the Armonica. With great esteem and respect,

I am, &c.

Mr Strahan's Queries, and Dr Franklin's Answers.

DEAR SIR,-In the many conversations we have had together about our present disputes, we perfectly agreed in wishing they may be brought to a speedy and happy conclusion. How this is to be done is not so easily ascertained.

Two objects, I humbly apprehend, his majesty's servants have now in contemplation. 1st. To relieve the colonies from the taxes complained of, which they certainly had no hand in imposing. 2d. To preserve the honour, the dignity, and the supremacy of British legislature over all his majesty's dominions. As I know your singular knowledge of the subject in question, and am as fully convinced of your cordial attachment to his majesty, and your sincere desire to pro
