opinion, the test of value in matters of invention, and that a discovery which can be applied to no use, or is not good for something, is good for nothing. I took for the basis of my calculation the supposition that there are 100,000 families in Paris, and that these families consume in the night half a pound of bougies, or candles per hour. I think this is a moderate allowance, taking one family with another; for though I believe some consume less, I know that many consume a great deal more. Then estimating seven hours per day, as the medium quantity between the time of the sun's rising and ours, he rising during the six following months from six to eight hours before noon, and there being seven hours of course per night in which we burn candles, the account will stand thus :-- In the six months between the twentieth of March and the twentieth of September, there are Nights Hours of each night in which we burn candles Multiplication gives for the total num ber of hours These 1,281 hours multiplied by 100,000, 183 7 1,281 128,100,000 64,050,000 pound, pound, makes the sum of ninety-six livres tournois 96,075,000 An immense sum! that the city of Paris might save every year, by the economy of using sunshine instead of candles. If it should be said, that people are apt to be obstinately attached to old customs, and that it will be difficult to induce them to rise before noon, consequently my discovery can be of little use: I answer, Nil desperandum. I believe all who have common sense, as soon as they have learnt from this paper that it is daylight when the sun rises, will contrive to rise with him; and, to compel the rest, I would propose the following regulations: First. Let a tax be laid of a louis per window, on every window that is provided with shutters to keep out the light of the sun. Second. Let the same salutary operation of police be made use of to prevent our burning candles, that inclined us last winter to be more economical in burning wood; that is, let guards be placed in the shops of the wax and tallow chandlers, and no family be permitted to be supplied with more than one pound of candles per week. Third. Let guards also be posted to stop all the coaches, &c. that would pass the streets after sun-set, except those of physicians, surgeons, and midwives. Fourth. Every morning, as soon as the run rises, let all the bells in every church be set ringing; and if that is not sufficient, let cannon be fired in every street, to wake the sluggards effectually, and make them open their eyes to see their true interest. Alp All the difficulty will be in the first two or three days: after which the reformation will be as natural and easy as the present irregularity: for, ce n'est que le premier pas qui coute. Oblige a man to rise at four in the morning, and it is more than probable he shall go willingly to bed at eight in the evening; and, having had eight hours sleep, he will rise more willingly at four the morning following. But this sum of ninety-six millions and seventy-five thousand livres is not the whole of what may be saved by my economical project. You may observe, that I have calculated upon only one half of the year, and much may be saved in the other, though the days are shorter. Besides, the immense stock of wax and tallow left unconsumed during the summer will probably make candles much cheaper for the ensuing winter, and continue them cheaper as long as the proposed reformation shall be supported. For the great benefit of this discovery, thus freely communicated and bestowed by me on the public, I demand neither place, pension, exclusive privilege, nor any other reward whatever. I expect only to have the honour of it. And yet I know there are little envious minds who will, as usual, deny me this, and say, that my invention was known to the ancients, and perhaps they may bring passages out of the old books in proof of it. I will not dispute with these people, that the ancients knew not the sun would rise at certain hours; they possibly had, as we have, almanacks that predicted it but it does not follow from thence, that they knew he gave light as soon as he rose. This is what I claim as my discovery. If the antients knew it, it night have been long since forgotten, for it certainly was unknown to the moderns, at least to the Parisians, which to prove, I need use but one plain simple argument. They are as well-instructed, judicious and prudent a people as exist any where in the world, all professing, like myself, to be lovers of economy; and, from the many heavy taxes required from them by the necessities of the state, have surely an abundant reason to be economical. I say it is impossible, that so sensible a people, under such circumstances, should have lived so long by the smoaky, unwholesome and enormously expensive light of candles, if they had really known, that they might have had as much pure light of the sun for nothing. I am, &c, An ABONNE. TO JOHN ALLEYNE, ESQ. DEAR JACK, On early Marriages. Craven Street, Aug. 9, 1768. YOU desire, you say, my impartial thoughts on the subject of an early marriage, by way of answer to the numberless objections, that have been made by numberless persons, to your own. You may remember, when you consulted me on the occasion, that I thought youth on both sides to be no objection. Indeed, from the marriages that have fallen under my observation, I am rather inclined to think, that early ones stand the best chance of happiness. The temper and habits of the young are not yet become so stiff and uncomplying, as *From the Gentleman's Magazine for May 1799. Editor. when when more advanced in life; they form more easily to each other, and hence many occasions of disgust are removed. And if youth has less of that prudence, which is necessary to manage a family, yet the parents and elder friends of young married persons are generally at hand to afford their advice, which amply supplies that defect; and by early marriage, youth is sooner formed to regular and useful life; and possibly some of those accidents or connections, that might have injured the constitution, or reputation, or both, are thereby hap pily prevented. Particular circumstances of particular persons may possibly sometimes make it prudent to delay entering into that state; but in general, when nature has rendered our bodies fit for it, the presumption is in nature's favour, that she has not judged amiss in making us desire it. Late marriages are often attended, too, with this further inconvenience, that there is not the same chance that the parents shall live to see their offspring educated. "Late children," says the Spanish proverb," are early orphans." A melancholy reflection to those whose case it may be! With us in America, mariages are generally in the morning of life; our children are therefore educated and settled in the world by noon; and thus, our business being done, we have an afternoon and evening of cheerful leisure to our-selves, such as our friend at present enjoys. By these early marriages we are blessed with more children; and from the mode among us, founded by nature, of every mother suckling and nursing her own child, more of them are raised. Thence the swift progress of popula tion among us, unparalleled in Europe. In fine, I am glad you are married, and congratulate you most cordially upon it. You are now in the way of becoming a useful |
