The number of females in the State of Massachusetts engaged in the various manufactures of cotton, straw-platting, etc., has been estimated at forty thousand, and the annual value of their labor at one hundred dollars each on an average, or four millions of dollars for the whole. From the facts stated in the letters of Messrs. Mills and Clark above cited, it appears there is a difference of not less than fifty per cent. between the earnings of the least educated and of the best educated operatives—between those who make their marks instead of writing their names, and those who have been acceptably employed in school-keeping. Now suppose the whole forty thousand females engaged in the various kinds of manufactures in that commonwealth to be degraded to the level of the lowest class, it would follow that their aggregate earnings would fall at once to two millions of dollars. But, on the other hand, suppose them all to be elevated by mental cultivation to the rank of the highest, and their earnings would rise to the sum of six millions of dollars annually.
There can be no doubt but that education, or the want of it, affects the pecuniary value of female labor in the ordinary domestic employments of the sex not less than in manufactures. If, then, the females of the thirty states of the Union be estimated at eight millions—and the number sustaining the relations of daughters, wives, and mothers must exceed the supposition—the effect of giving them all an education equal to the best would at once raise their earnings, annually, two hundred millions of dollars! But this is the lowest sense in which we can estimate the value of education, even in the sterner sex. This sum, vast as it may seem, is as dross to gold when compared with the refining and elevating influence which eight millions of educated females would exert upon the domestic and social institutions of our country, in uplifting our national character and improving the condition of the race.
Not more than thirty years ago it was uncommon for a glazier's apprentice, even after having served an apprenticeship of seven years, to be able to cut glass with a diamond without spending much time and destroying much of the glass upon which he worked. But the invention of a simple tool has put it into the power of the merest tyro in the trade to cut glass with facility, and without loss. A man who had a mind, as well as fingers, observed that there was one direction in which the diamond was almost incapable of abrasion or wearing by use. The tool not only steadies the diamond, but fastens it in that direction.
The operation of tanning leather consists in exposing a hide to the action of a chemical ingredient, called tannin, for a length of time sufficient to allow every particle of the hide to become saturated with the solution. In making the best leather, the hides used to lay in the pit for six, twelve, or eighteen months, and sometimes for two years, the tanner being obliged to wait all this time for a return of his capital. By the modern process, the hides are placed in a close pit, with a solution of the tannin matter, and the air being exhausted, the liquid penetrates through every pore and fiber of the skin, and the whole process is completed in a few days.
The bleaching of cloth, which used to be effected in the open air, and in exposed situations where temptation to theft was offered, and in England hundreds and probably thousands of men have yielded and forfeited their lives, is now performed in an unexposed situation, and in a manner so expeditious, that cloth is bleached as much more rapidly than it formerly was as hides are tanned.
It is stated by Lord Brougham, in his beautiful Discourse on the Advantages of Science, that the inventor of the new mode of refining sugar made more money in a shorter time, and with less risk and trouble, than perhaps was ever realized from any previous invention.
Intelligence also prevents loss as well as makes profits. How much time and money have been squandered in repeated attempts to invent machinery, after a principle had been once tested and had failed through some defect inherent and natural, and therefore insuperable! Within thirty years not less than five patents have been taken out, in England and the United States, for a certain construction of paddle-wheels for a steamboat, which construction was tested and condemned as early as 1810.[42] A case once came within my own knowledge, says Mr. Mann, of a person who spent a fortune in mining for coal, when a work on geology, which would have cost but a dollar, and might have been read in a week, would have informed him that the stratum where he began to excavate belonged to a formation lower down in the natural series than coal ever is, or, according to the constitution of things, ever can be found. He therefore worked into a stratum which must have been formed before a particle of coal, or even a tree, or a vegetable existed on the planet. Numerous similar and equally striking illustrations might be cited, but this is not necessary.
These are a few specimens, on familiar subjects, taken almost at random, for the purpose of showing the inherent superiority of any association or community, whether small or great, where mind is a member of the partnership. What is true of the above-mentioned cases is true of the whole circle of those arts by which human life is sustained and human existence comforted, elevated, and embellished. Mind has been the improver, for matter can not improve itself, and improvement has advanced in proportion to the number and culture of the minds excited to activity and applied to the work.
Similar advancements have been effected throughout the whole compass of human labor and research; in the arts of Transportation and Locomotion, from the employment of the sheep and the goat as beasts of burden, to the steam-engine and the rail-road car; in the art of Navigation, from the canoe clinging timidly to the shore, to steam-ships which boldly traverse the ocean; in Hydraulics, from carrying water by hand in a vessel or in horizontal aqueducts, to those vast conduits which supply the demands of a city, and to steam fire-engines which throw a column of water to the top of the loftiest buildings; in the arts of Spinning and Rope-making, from the hand distaff to the spinning-frame, and to the machine which makes cordage or cables of any length, in a space ten feet square; in Horology or Time-keeping, from the sun-dial and the water-clock to the watch, and to the chronometer, by which the mariner is assisted in measuring his longitude, and in saving property and life; in the extraction, forging, and tempering of Iron and other ores having malleability to be wrought into all forms and used for all purposes, and supplying, instead of the stone hatchet or the fish-shell of the savage, an almost infinite variety of instruments, which have sharpness for cutting or solidity for striking; in the art of Vitrification or Glass-making, giving not only a multitude of commodious and ornamental utensils for the household, but substituting the window for the unsightly orifice or open casement, and winnowing light and warmth from the outward and the cold atmosphere; in the arts of Induration by Heat, from bricks dried in the sun to those which withstand the corrosion of our climate for centuries or resist the intensity of the furnace; in the arts of Illumination, from the torch cut from the fir or pine tree to the brilliant gas-light which gives almost a solar splendor to the nocturnal darkness of our cities; in the arts of Heating and Ventilation, which at once supply warmth for comfort and pure air for health; in the art of Building, from the hollowed trunk of a tree or the roof-shaped cabin, to those commodious and lightsome dwellings which betoken the taste and competence of our villages and cities; in the art of Copying or Printing, from the toilsome process of hand-copying, where the transcription of a single book was the labor of months or years, and sometimes almost of a life, to the power printing-press, which throws off sixty printed sheets in a minute; in the art of Paper-making, from the preparation of the inner bark of a tree, cleft off and dried at immense labor, to machinery from which there jets out an unbroken stream of paper with the velocity and continuousness of a current of water; in the art of Painting, from the use of the crayon, and artificial colors imperfectly blended, requiring whole days to present an incomplete picture, to the production, as by enchantment, of perfect likenesses in nature's own penciling, executed in a few seconds; in the art of Telegraphing, from communicating information by signs which may be seen from one station to another, to conveying intelligence to any given distance with the velocity of lightning; and, in addition to all these, in the arts of Moulding and Casting, of Designing and Engraving, of Preserving materials and of Changing their color, of Dividing and Uniting them, etc., etc., an ample catalogue, whose very names and processes would fill volumes.
Now, for the perfecting of all these operations, from the tedious and bungling process to the rapid and elegant; for the change of an almost infinite variety of crude and worthless materials into useful and beautiful fabrics, mind has been the agent. Succeeding generations have outstripped their predecessors just in proportion to the superiority of their mental cultivation. When we compare different people or different generations with each other, the diversity is so great that all must behold it. But there is the same kind of difference between contemporaries, fellow-townsmen, and fellow-laborers. Though the uninstructed man works side by side with the intelligent, yet the mental difference between them places them in the same relation to each other that a past age bears to the present. If the ignorant man knows no more respecting any particular art or branch of business than was generally known during the last century, he belongs to the last century, and he must consent to be outstripped by those who have the light and knowledge of the present. Though they are engaged in the same kind of work, though they are supplied with the same tools or implements for carrying it on, yet, so long as one has only an arm, but the other has an arm and a mind, their products will come out stamped and labeled all over with marks of contrast; inferiority and superiority, both as to quantity and quality, will be legibly written on their respective labors.
