While the foregoing series of inventions placed an almost unlimited supply of cotton yarn at the disposal of the weaver, the machinery as yet introduced was still incapable of providing yarn fit for the finest grades of cotton cloth. The "water-frame" indeed spun abundant twist for warps, but it could not furnish the finest qualities of yarn, because these were too tenuous to bear safely the pull of the rollers while they wound themselves on the bobbin. Samuel Crompton, a young weaver living near Bolton, possessed the ingenuity needful to remove this difficulty. He succeeded in combining in one machine, which from its nature is happily called the "mule," the several excellences of Hargreaves' spinning-jenny and Arkwright's water-frame. Copying after the latter, the mule has a system of rollers to reduce the roving; copying after the former it has spindles without bobbins to give the twist; and the thread is stretched and spun at the same time by the spindles after the rollers have ceased to give out the rove. "The distinguishing feature of the mule is that the spindles, instead of being stationary, as in both the other machines, are placed on a movable carriage which is wheeled out to the distance of fifty-four or fifty-six inches from the roller beam, in order to stretch and twist the thread, and wheeled in again to wind it on the spindles. In the jenny, the clasp which held the rovings was drawn back by the hand from the spindles; in the mule, on the contrary, the spindles recede from the clasp, or from the roller-beam which acts as a clasp. The rollers of the mule draw out the roving much less than those of the water-frame, and they act like the clasp of the jenny by stopping and holding fast the rove, after a certain quantity has been given out, whilst the spindles continue to recede for a short distance farther, so that the draught of the thread is in part made by the receding of the spindles. By this arrangement, comprising the advantages both of the roller and the spindles, the thread is stretched now gently and equably, and a much finer quality of yarn can therefore be produced."

The ingenuity of Hargreaves, Arkwright, and Crompton had been exercised to provide the weaver with yarn, and had now indeed provided him with more yarn than he could use; the spinster had beaten the weaver, just as the weaver had previously beaten the spinster; and the making of cotton cloth seemed likely to continue sluggish, because the yarn could not be woven any faster than a skilled workman could weave it with Kay's improved fly-shuttle. In the summer of 1784, a Kentish clergyman named Edmund Cartwright, being in conversation with some Manchester gentlemen, one of whom observed that, "as soon as Arkwright's patent expired so many mills would be erected and so much cotton spun that hands would never be found to weave it," replied, "Arkwright must then set his wits to work to invent a weaving-mill." Notwithstanding the unanimous opinion expressed by the Manchester gentlemen, that such a weaving-machine was wholly impracticable, the clergyman himself within three years had invented and brought into successful operation the "power-loom." Subsequent inventors improved the idea which Cartwright originated, and before 1834 there were not less than 100,000 power-looms at work in Great Britain alone.[3]

Substantially the same machinery invented for carding and spinning and weaving cotton was very shortly and successfully applied to the carding and spinning and weaving of wool, because the wisdom of Nature imparted to them both the same sort of tenacity of fibre, the same capacity in that fibre to be spun into a thread of indefinite length by means of the little loops or kinks easily interlocking contiguous fibres into a single thread, which two obvious resemblances gave an identical name to the animal and vegetable products otherwise so different from each other.

The spirit of Invention, one of the chief conditions in the production of material commodities, thus simply illustrated along the line of a single manufacture, may serve us for a sample of similar improvements taken and taking place in scores upon scores of other lines of effort and production. The principle is the same in all cases past and present and still to come, namely this, to throw the strain from the mind and muscles of men upon the forces and agencies of free Nature, with which the world around us is crowded in our behalf, and which are waiting to slave in the service of mankind without rest and without fatigue,—without money and without price.

(c) Freedom. By far the most important of all the conditions, under which the production of material commodities goes broadly forward, is liberty of action on the part of the individual; because, wherever such liberty is conceded, association and invention and all other needful conditions follow right along by laws of natural sequence. By liberty of individual action is meant the practical right of every man to employ his own efforts for the satisfaction of his own wants in his own way, whether directly or through exchange. Each man's right of individual freedom is limited of course by every other man's right to equal freedom, which the first man is not at liberty to infringe; and also, in certain few and limited respects, by what is sometimes called the "general good," the judge of the application of which must be the government under which the man lives. With these limitations, which are few in number and never serious in degree when rightly applied, and which limit in common all other rights whatsoever, the right of every man to buy and sell and get gain is just as fully a right as the right of breathing. It stands on the same impregnable ground. It is a natural and self-evident and inalienable right, with which each man has been endowed by his Creator, to put forth efforts for his own well-being and for those dependent upon him, either directly or by means of efforts exchanged with other men equally free; and he is a slave in spirit and position, who tamely submits to have his own rights of buying and selling curtailed, or to stand by and see the rights of his fellow-citizens similarly curtailed, unless such act of interference and curtailment on the part of his Government be justified by a solid proof that some other public or private rights, which are at least as well based as his own, would be endangered by the exercise of his own.

In what cases may a Government properly step in to regulate or prohibit the buying and selling of its citizens? Hundreds of inductions extending through hundreds of years have been carefully and logically conducted in order to reach a just and comprehensive answer to this question; and in all probability the cases have been inductively ascertained for all time, and they are these: such buying and selling may be controlled and prohibited, as are proven to be contrary (1) to the public Morals, (2) to the public Health, (3) to the public Revenue. All other buying and selling may be safely assumed to be both profitable to the parties to it, and also useful to the Commonwealth in general; and any interference with it by public authority is a high-handed infringement of natural rights, a blow aimed at the life and source of property. These wrongful strokes at private rights, this restriction on the freedom of individuals to exchange products for their own welfare, is now mostly confined in civilized countries to the region of Taxation. Within this region the wrongs are still frightful. Judge Cooley, in his "Principles of Constitutional Law," states the matter as follows: "Constitutionally a tax can have no other basis than the raising of revenue for public purposes; and whatever governmental action has not this basis is tyrannical and unlawful. A tax on imports, therefore, the purpose of which is not to raise a revenue, but to discourage and indirectly prohibit some particular import for the sake of some home manufacturer, may well be questioned as being merely colorable, and therefore not warranted by constitutional principle."

Formerly, governments interfered almost beyond belief with the freedom of their people in all industrial and commercial action; dictating what should and what should not be grown and manufactured, what should and what should not be exported and imported; decreeing by proclamation or enacting by statute, the number of apprentices each artisan might employ, and the years during which these must serve as such, and the conditions under which they might then work as journeymen; the materials to be used in woven fabrics, and even the widths and other minor features of such fabrics, were prescribed in the foremost of the European nations; in the reign of St. Louis of France, a "Book of Trades" was issued under royal authority and is still extant, which organizes minutely and subjects to cumbersome rules more than one hundred separate industries as then practised; England was the country of the great trading "Companies," and of all of these the same may be said as Adam Smith said of the Turkey Company formed in 1579, namely, it was "a strict and oppressive monopoly"; among others there were the African Company established in 1530, the Russia Company beginning its operations in 1553, the East India Company chartered on the very last day of the seventeenth century and going out of existence in our own time, and the Hudson's Bay Company, chartered in 1670 and so having the sole control in trade of a region forty times larger than all England; while the colonial system prevailing for two centuries in all the countries of Western Europe regulated the commerce and controlled the manufactures in the colonies with a single eye to the benefits of the mother country, as those were conceived of under the wretched Mercantile system.

Happily, since governments have become more enlightened than formerly, they are perceiving for the most part that they have not the least right to interfere in those ways or in any ways with the natural right of their people to make and grow freely all material commodities, and to buy and sell these freely in the best markets wherever these markets are to be found; and they are also perceiving, that by such interference incalculable losses of property and indefinite retardations of progress are caused to their people, as well as weakness to themselves as governments through a more difficult gathering of taxes and a harder maintenance of prestige and power.

The only motive to a mutual exchange of services, whether in one or in all of their three kinds, that is to say, to a free production of commodities and services and credits, is always and everywhere the mutual benefit of the two parties exchanging. After all the processes have been gone through with and the exchanges are consummated, all the parties are richer than before, that is, they have more satisfactions, otherwise the processes and exchanges would instantly cease. Therefore, a universally free production benefits everybody, and harms nobody. Moreover, under a system of free production, every man is allowed under the stimulus of self-interest to work away at those obstacles to the gratification of human desires which he feels himself best able to overcome, to follow the bent of his own mind, and to avail himself of all those free helps in his peculiar work which Nature offers to him. Under these circumstances, obstacles give way in all directions; the amount of material products produced is vastly augmented, the number and variety and excellence of personal services proffered are indefinitely increased, and credits compelling the Future to pay tribute to production are multiplied; the diversified and rapidly increasing desires of all persons in such a community are readily met through profitable exchanges; while all peculiar facilities natural and acquired are taken immediate advantage of, the diversities of relative advantage in production become marked in all directions, and a new day of industrial and commercial prosperity is ushered in. Because under freedom all men are sure to dispose of their industrial efforts to the best advantage, they have the strongest possible motives to put them forth; since they can purchase with them what they will and when they will, and where they will. Thus freedom leads to extended association, and also to the invention of machinery and all labor-saving appliances.

3. We are now in position to understand thoroughly the ultimate Grounds of the production of material commodities. We have seen, that these commodities have been multiplying in number and variety and excellence ever since the beginnings of history, that they are everywhere multiplying now at a rate hitherto unprecedented and undreamed of, and that improved and improving methods of transportation by land and sea are now carrying these back and forth to the ends of the earth. What is the principle, under which these things have been done, are now being done, and are certain to be done in the time to come?
