About 1835 Elkington’s system of drainage, which among the more advanced agriculturists, at any rate, had been used for half a century, was superseded by that of James Smith of Deanston, a system of thorough drainage and deep ploughing, which effected a complete revolution in the art of draining, and holds the field to-day.  Hitherto the draining of land had been done by a few drains where they were thought necessary, which was often a failure.  Smith initiated a complete system of parallel underground drains, near enough to each, other to catch all the superfluous water, running into a main drain which ran along the lowest part of the ground.  His system has also been called ‘furrow or frequent draining’, as the drains were generally laid in the furrows from two to two-and-a-half feet deep at short intervals.  Even then the tributary drains were at first filled in with stones 12 inches deep, as they had been for centuries, and sometimes with thorns, or even turves, as tiles were still expensive; and the main was made of stonework.  However, the invention of machines for making tiles cheapened them, and the substitution of cylindrical pipes for horse-shoe tiles laid on flat soles still further lowered the cost and increased the efficiency.[613] In 1848, Peel introduced Government Drainage Loans, repayable by twenty-two instalments of 6 1/2 per cent.  This was consequently an era of extensive drainage works all over England, which sorely needed it; but even now the work was often badly done.  In some cases it was the custom for the tenant to put in as many tiles as his landlord gave him, and they were often merely buried.  At Stratfieldsaye, for instance, where the Iron Duke was a generous and capable landlord, the drains were sometimes a foot deep, while others were 6 feet deep and 60 feet apart,[614] although the soil required nothing of the kind.

Vast sums were also spent on farm-buildings, still often old and rickety, with deficient and insanitary accommodation; in Devonshire the farmer was bound by his lease to repair ’old mud and wooden houses’, at a cost of 10 per cent. on his rent, and there were many such all over England.  Farm-buildings were often at the extreme end of the holding, the cattle were crowded together in draughty sheds, and the farmyard was generally a mass of filth and spoiling manure, spoiling because all the liquid was draining away from it into the pool where the live stock drank; a picture, alas, often true to-day.  It was to bring the great mass of landlords and farmers into line with those who had made the most of what progress there had been, that the Royal Society was founded in 1838, in imitation of the Highland Society, but also owing to the realization of the great benefits conferred on farming during the last half-century by the exertions of Agricultural Societies, the Smithfield Club Shows having especially aided the breeding of live stock.
