Writing in 1847, Porter said rents had doubled since 1790.[648] In Essex farms could be pointed out which were let in 1790 at less than 10s. an acre, but during the war at from 45s. to 50s. In 1818 the rent went down to 35s., and in 1847 was 20s.

In Berks. and Wilts. farms let at 14s. per acre in 1790, rose by 1810 to 70s., or fivefold; sank in 1820 to 50s., and in 1847 to 30s. In Staffordshire farms on one estate let for 8s. an acre in 1790, rose during the war to 35s., and at the peace were lowered to 20s., at which price they remained. Owing to better farming light soils had been applied to uses for which heavy lands alone had formerly been considered fit, with a considerable increase of rent.

On the Duke of Rutland's[649] Belvoir estate, of from 18,000 to 20,000 acres of above average quality, rents were in—

1799 19s. 33/4d.an acre.
181225s. 83/4d."
183025s. 13/4d."
185036s. 8d."

But the Dukes of Rutland were indulgent landlords and evidently took no undue advantage of the high prices during the war, a policy whose wisdom was fully justified afterwards.

It was the opinion of most competent judges, even after the abolition of the Corn Laws, that English land would continue to rise in value. Porter stated that the United Kingdom could never be habitually dependent on the soil of other countries for the food of its people, there was not enough shipping to transport it if it could.[650]

Caird prophesied that in the next eighty years the value of land in England would more than double. The wellnigh universal opinion was that as the land of England could not increase, and the population was constantly increasing, land must become dearer. Men failed to foresee the opening of millions of acres of virgin soil in other parts of the world, and the improvement of transport to such an extent that wheat has occasionally been carried as ballast. About twenty-five or thirty years after these prophecies their fallacy began to be cruelly exposed.[651]

About 1853[652] matters began to mend, chiefly owing to the great expansion in trade that followed the great gold discoveries in America and Australia. Then, came the Crimean War, with the closing of the Baltic to the export of Russian corn, wheat in 1855 averaging 74s. 8d., and in the next decade the American War crippled another competitor, the imports of wheat from the United States sinking from 16,140,000 cwt in 1862, to 635,000 cwt. in 1866. From 1853 until 1875 English agriculture prospered exceedingly, assisted largely by good seasons. Between 1854 and 1865 there were ten good harvests, and only two below the average. Prices of produce rose almost continuously, and the price and rent of land with them. The trade of the country was good, and the demand for the farmer's products steadily grew; the capital value of the land, live stock, and crops upon it, increased in this period by £445,000,000.[653]

It appeared as if the abolition of the Corn Laws was not to have any great effect after all.

Now at last the great body of farmers began to approach the standard set them long before by the more energetic and enterprising. Early maturity in finishing live stock for the market by scientific feeding probably added a fourth to their weight The produce of crops per acre grew, and drainage and improvements were carried out on all sides, the greatest improvement being made in the cultivation and management of strong lands, of which drainage was the foundation, and enabled the occupier to add swedes to his course of cropping.[654]
