The main causes of that change are stated in a public letter which I addressed to my constituents shortly before the General Election of 1847, from which the following is an extract. The latter part of this extract refers to a question in some respects distinct—namely, the difficulty there would be in subsequently maintaining inviolate the Corn Law of 1842 in the event of its suspension in 1845 on account of apprehended scarcity. I will give, however, the extract entire, as the reasoning applies with nearly equal force to the principle of continued protection as well as to the policy of its revival after having been once in abeyance. The letter is dated July, 1847. _To the Electors of Tamworth._ My confidence in the validity of the reasons on which I had myself heretofore relied for the maintenance of restrictions on the import of corn had been materially weakened. It had been weakened by the conflict of arguments on the principle of a restrictive policy; by many concurring proofs that the wages of labour do not vary with the price of corn; by the contrast presented in two successive periods of dearth and abundance, in the health, morals, and tranquillity and general prosperity of the whole community; by serious doubts whether, in the present condition of this country, cheapness and plenty are not ensured for the future in a higher degree by the free intercourse in corn, than by restrictions on its importation for the purpose of giving protection to domestic agriculture. It had been weakened also by the following considerations, which were in a great degree new elements in forming a judgment on this vital matter. The general repeal of prohibitory duties, and the recent application of the principles of free trade to almost all articles of import from abroad, made the Corn Laws the object of more searching scrutiny and more invidious comment, and narrowed the ground on which their defence could be maintained. Among the articles of foreign import prohibited up to the year 1842, and then admitted at low rates of duty, were some important articles of agricultural produce, salted and fresh meat, oxen, sheep, cows, etc. You probably recollect the panic which this admission caused—the forced sale of stock, the prophecies that it would be impossible to compete with the foreign grazier, and that meat would be reduced to threepence a pound. Five years have passed since this great change in the law took place, and your own experience will enable you to judge whether the panic was well founded, and whether the prophecies have been fulfilled. The complete failure of these prophecies had naturally had its effect on public opinion with regard to the probable consequences of a free intercourse in other articles of agricultural produce.
