But this form of Capital, as well as all other forms of the same, is perpetually wearing out, that is to say, is gradually losing its power to contribute as at first to the present and future processes of production. This loss is in the very nature of things,—in the very nature of all Capital. The great Father never intended that His children should cease from work. He has ordered all things so, that they cannot cease from work, and continue to live in any comfort and progress. Value, as we have already thoroughly learned, is not a quality that can be put into anything to stay there: it is a recurring relation of mutual services between man and man; and each of these services of the three kinds involves recurring Efforts. Capital is a form of Value; and, consequently, it cannot possibly take on a shape not subject to the law of diminishing returns. This is deductive proof. And precisely the same result is reached by Induction. Men have noticed and recorded the fact at all times, and have made provision for it in their pecuniary calculations, that tools and machinery need to be repaired and then replaced, that the current interest on moneyed capital tends to decline from generation to generation in all progressive countries, and also that lands and other forms of real estate so lose their productive and rental power unless cared for in renovation that men migrate and emigrate in consequence.

How much Rent shall the tenant pay to the landlord for the present use of the latter's old lands? Or in other words, how much shall be added to the going price of the product on account of the diminishing return due for the use of the old landed capital? This is a hard question to answer: probably the hardest question that is ever asked in practical Economics. Mr. Gladstone wrestled with it as complicated with a larger political question in passing the Irish Land Bill of 1881. Another honest athlete, Mr. Parnell, wrestled with it upon the same parliamentary arena. Scores of able and practical statesmen in Great Britain, and elsewhere, have struggled to reach a practical answer to this question; and scores of able and theoretical economists in all countries have striven to reach a theoretical answer to it. Most of these answers have been inharmonious, and many of them contradictory, with each other. The Land Bill of 1881 created a parliamentary Commission, whose duty and authority it was, to visit the Irish counties in person, to gain information in detail, to take sworn testimony of all the parties concerned, and then to lift or lower rents according to their discretion. The discontent of the Irish tenants in general was considerably mollified by the action of this Commission; while the debates and wrangles of the parliamentary session of 1889, and the persistent agitations for Home Rule (an agitation at once political and economical), show that the results of the work of that Commission were not wholly satisfactory.

(a) It is easy enough to see why the solution of this general problem is so extremely difficult. The new is mixed in with the old. The result of the old labor and capital is a productive piece of land; the current labor and capital is expended upon the same piece to make it more productive; the same sort of thing is done now that was done then, and the results of the two are now thoroughly intermixed; there were original free utilities in soil and growths and deposits, but these had and have no value and can never yield rent; the old labor and capital improved the soil by clearing and drainage and fertilizers, and made the growths and deposits more valuable and accessible, so that even the old onerous was more or less transformed into the original gratuitous; and now the new onerous, the fresh cultivation and fertilization and betterments generally, in soils and roads and buildings, are inextricably commingled with former betterments of the same general kind and with the original free gifts of Nature. No wonder the Commission of 1881 found difficulty in determining what was what and which was which! No wonder that Irish tenants on long leases quarrel with their landlords about the betterments, how much is new, how much is old! It is clear, that when the lease is ended, the landlord ought to compensate the tenant for all that portion of the latter's betterments, which is not already worn out; it is equally clear, that the tenant ought to be willing to pay a fair rent for the use of the unexpended betterments of the landlord and his predecessors; while there is room and verge enough for endless disputes between them as to the respective amounts of these, and consequently as to the amounts of rent and of its remissions.

These difficulties and intricacies do not belong to the principles of the Science of buying and selling, which are in the main clear and certain in their action, but are incidents of determining in certain cases what that is, which is bought and sold. Parties in interest in all kinds of buying and selling are sometimes compelled to go to the courts in order to have the Law decide what their respective rights are as buyers and sellers; but this is no fault of Political Economy as a science, or of trading as an art; two men in all cases make their own bargain, according to their own estimate of the respective rendering and receiving of each; if the uncertainties of language, the misconception on the part of one or both of the terms agreed upon, and the misapprehension of some of the circumstances of the case, breed confusion and litigation, all this cannot be justly charged to the science of Political Economy.

Nevertheless, it is into these incidental intricacies and uncertainties, that Henry George's now famous theory of landed rents and the taxation of them, strikes its roots. Instead of building his structure upon firm and open ground, so that thoughtful men can see that his basis is solid and scientific, Mr. George dashes at once into a thicket and lays his foundations with quickness and assurance where all is dark and doubtful, or at best where all is rather incidental than fundamental and demonstrable, and pretty soon displays a superstructure that appears attractive both without and within, through whose airy halls he knows how to conduct to their delight the credulous and discontented, and on whose walls hang plausible pictures calculated to invite and hold the attention of the masses. Let the perfect integrity and rhetorical ability of Mr. George be freely conceded; let it be freely conceded also, that he teaches in his books and lectures a great deal of vastly important industrial truth in a popular way so as to accomplish great good, such, for example, as the imperative need of greater simplicity in taxation, and the indisputable right of the people to their liberty in buying and selling; yet it must at the same time be owned, that he has never yet found out exactly what Value is in general, consequently what are the causes of value in lands, and what are the nature and grounds of Rent. Something more of patient and radical analysis at the outset, and of logical and scientific unfolding afterwards, would have made Henry George one of the chief benefactors of his age.

(b) It is also very easy to see, that the current price of produce, that is, what is gotten in return for the sale of what is gotten out of the land-parcels, must have a dominant influence upon what can be paid as rent for the use of the parcels. Unless the return from the produce be sufficient to reward at current rates the present labor and capital employed upon the parcel, the parcel will not continue to be cultivated at all, otherwise men would act without a motive for action, which they never do; unless, therefore, the price of produce be more than high enough to repay current wages and profits, there will be nothing left for Rent; and, consequently, the amount of the rent that can continue to be paid for lands will be the difference between the going price of what is produced from them and the current expenses of cultivating them. Here, as everywhere else within the domain of Exchange, Competition exerts its beneficent action. If one dealer, or ten, endeavors to put a price upon the produce more than enough to pay current wages and profits with a fair margin for the diminishing rate of rent, there are a plenty of others, dealers in the same grade of produce, who will be content with a fair return for present and past expenditure of labor and capital; and the action of these will effectually debar the others from exorbitant rates. The price of produce, accordingly, under free competition, is the divinely appointed regulator of landed rents. It regulates also, though more indirectly, the current rates of wages and profits in agriculture.

Very different from this is Ricardo's doctrine of Rent. He makes everything turn on the Cost of Production of the Produce, which is Effort, ignoring the ever-varying demands for the produce, which is Desire. His doctrine, too famous and too long received for us to pass by in this connection, though now superannuated, was for substance, this: there are some lands in every country whose produce just repays the expenses of cultivation, and consequently yields no margin for rent; and the cost of production on these rentless and poorest lands under cultivation, will determine the price of the produce; and as there can be but one price in the same market, the produce raised on more fertile land will be sold for the same price, and this price, besides paying the cost of cultivation, will yield a rent rising higher according as the land is more fertile; so that the rent paid on any land is always a measure of the excess of productiveness of that land over the least productive land under paying cultivation; and therefore, an increased demand for food in consequence of increased population, and the higher price resulting, will force cultivation down upon still poorer soils, or compel a higher culture for less remunerative returns on the old soils, according to the law of diminishing returns, which in either case will raise the rents on all the soils above that grade that just repays the expenses of cultivation; so that it is the sole interest of landlords, as such, that population should be dense and food high, their interest being directly antagonistic to that of the other classes of the community.

(c) Finally, in this connection, it is easy enough to see, what were the motives on the part of the landlords, and what were the results on the part of the masses, of Great Britain, in putting on and keeping on the infamous Corn Laws, so-called, which were repealed forever in 1846. The Corn Laws forbade the importation of foreign cereals under heavy pecuniary penalties. The simple purpose of the landlords then governing England was to raise the price of their grain by shutting off Competition of foreigners by means of these prohibitory tariff-taxes. It was Protectionism pure and simple. It was designed to raise the price of bread to the masses of their countrymen, and often did raise it to the point of their starvation. But we have just seen, that the higher the price of the produce, the wider the margin for Rent for the lands that produce it. The Corn Laws of England enriched the landlords at the expense of all other classes and to the starvation of many of the poor. As has been well said, this was the most successful of all the many expedients that have been tried, "to fertilize the rich man's land by the sweat of the poor man's brow." The words of Daniel O'Connell, spoken Sept. 28, 1843, in his parliamentary fight against the high-tariff Corn Laws, were surfeited with truth and righteousness: "But what is the meaning of 'Protection'? It means an additional sixpence for each loaf; that is the Irish of it. If the landlord had not the protection, the loaf would sell for a shilling, but if he has protection, it will sell for one and sixpence. Protection is the English for sixpence; and what is more, it is the English for an extorted sixpence. The real meaning of 'Protection,' therefore, is robbery,—robbery of the poor by the rich."

At the present moment and for twenty-five years past, the public laws of the United States ostensibly relating to Taxes, have had an immense influence upon the value and rents of the agricultural lands of the country to depress them; because these laws have put up nearly or wholly impassable barriers to the coming in of those foreign goods, against which the farmers would naturally and profitably and inevitably have sold their surplus agricultural produce; by destroying the foreign market for farm products, these laws do in effect destroy a large part of the value of the farms of the country, and of what would otherwise be the rentals of a part of them; the Constitution of the country expressly forbids any taxation whatever of Exports, but these laws have precisely the same effect on the value of farm products if they were themselves forbidden to be exported, because those goods for which these would be otherwise exchanged for a profit are forbidden to be imported. A market for products is products in market. Thus these wretched laws lower the price of farm products, and consequently the value of farms and of their rents, and impoverish the farmers who are nearly one-half of the entire population of the country.

While these paragraphs are being written, comes the intelligence of the formation of the "North American Salt Company," whose purpose is in their own language "to unify and systematize the salt interests of the United States and Canada," and to this end "arrangements have been completed for the purchase and control of nearly all the existing salt properties of the North American continent." As this is a fair instance out of some thousands, in which a tariff-tax has the designed effect to lift or lower values which deeply concern the people, let us look at it for a moment. On the average of the past twenty-five years the tariff-tax on salt has in general doubled the cost of that necessary of life to the whole people of the United States. When Canada had no such tax, American makers of it sold salt sometimes to the Canadians 40% less than they would sell it to their own countrymen. On the basis of this United States tariff-tax (it would never have been dreamed of without it) this new company comes forward with a scheme of international monopoly to control in their own interest the price of a prime necessity of life. They propose to issue stock and bonds to the amount of $15,000,000, with which to buy up "the existing salt properties"; and they frankly avow in the prospectus from which we are quoting, that profits of $2,000,000 a year on their capital are justified by the present outlook. Whence are these immense profits to come? Out of the pockets of the masses of the American people bound hand and foot in the meshes of a legal monopoly, which they themselves allow themselves to be ensnared in! In a similar but more outrageous way, are bound up at the present moment in the secret so-called "Trusts" about forty more of the necessaries of life; each one of which, unless it be the "Standard Oil Trust," has its footing in a so-called "protective" tariff-tax, and would collapse instantly on the repeal of that!
