Now, we are not aware that Sir Robert Peel has ever _directly_ retracted these opinions, although many passages might be quoted from his speeches to show that he considered increased cheapness--the necessary result of his free-trade measures--some sort of compensation for the probable decline in the value of agricultural produce. But the income-tax and increased public burdens may fairly be set against any saving on the ground of cheapness, and the question remains precisely where it was before. The averages of sixteen years, excluding extraordinary impulses to an unnatural rise or fall, entitle us to assume that the British farmer cannot raise wheat profitably at lower prices than 56s. per quarter; and Sir Robert Peel, whatever may be the effect of his subsequent measures, once gave his solemn guarantee that, when prices should fall below 51s., there should be no foreign competition. We have no desire to rake up old matters of discussion, or to reflect upon pledges which may either have lapsed or been broken. Our present business with Sir Robert is simply to have his evidence as to the remunerating prices of corn, and that evidence we have stated above. We are, therefore, entitled to assume that any great and permanent decline of prices, following upon increased foreign imports, must have a most deleterious effect upon the agriculture of the country, unless some remedy can be found which shall lessen the cost of production. As usual, there is no lack of volunteers to suggest remedies. Dr Buckland, of iguanodon and icthyosaurus celebrity, discourses learnedly of subsoils and manures, and offers to show how acres of wheat may be raised upon soils hitherto yielding no other crop than rushes, ling, or heather. It is the misfortune of scientific men that they live in a world of their own; for, had the learned fossilist been aware of what has been passing around for the last twenty years, he would have known that no sane person ever questioned the truth of his assertions. With the aid of draining, manure, and other artificial appliances, corn may be grown almost anywhere within the compass of the British islands. No man disputes that. The simple question is: Will the corn, when grown, yield a fair return for the expenses attendant upon its growth? Until the geologists and chemists have acquired so much real practical knowledge as to be able to answer this query satisfactorily, they will best consult the public interest by confining themselves to their quarries and their laboratories. That agriculturist who should deny the advantages which his own science has derived from the aid of chemistry, would not only be an ungrateful, but an exceedingly unreasonable man; nevertheless, he cannot be charged with either ingratitude or folly if, after calculating the cost of the productive agent, and the value of the produce, he declines to expend his capital in forced improvements, which at the end of the year, and with diminished prices, must leave
