 contrive to make it so bad. They use much pottage made of coal-wort, which they call kail, sometimes broth of decorticated barley. The ordinary country-houses are pitiful cots, built of stone and covered with turfs, having in them but one room, many of them no chimneys, the windows very small holes and not glazed. The ground in the valleys and plains bear very good corn, but especially bears barley or bigge, and oats, but rarely wheat and rye.”

It is probable that no great change had taken place in Scotland from the end of the 15th century, except that tenants gradually became possessed of a little stock of their own, instead of having their farm stocked by the landlord. “The minority of James V., the reign of Mary Stuart, the infancy of her son, and the civil wars of her grandson Charles I., were all periods of lasting waste. The very laws which were made during successive reigns for protecting the tillers of the soil from spoil are the best proofs of the deplorable state of the husbandman.”

In the 17th century those laws were made which paved the way for an improved system of agriculture in Scotland. By a statute of 1633 landholders were enabled to have their tithes valued, and to buy them either at nine or six years’ purchase, according to the nature of the property. The statute of 1685, conferring on landlords a power to entail their estates, was indeed of a very different tendency in regard to its effects on agriculture. But the two Acts in 1695, for the division of commons and separation of intermixed properties, facilitated improvements.

From the Revolution to the accession of George III. the progress of agriculture was by no means so considerable as might be imagined from the great exportation of corn. It is probable that very little improvement had taken place, either in the cultivation of the soil or in the management of live stock, from the Restoration down to the middle of the 18th century. Clover and turnips were confined to a few districts, and at the latter period were scarcely cultivated at all by common farmers in the northern part of the island. Of the writers of this period, therefore, it is necessary to notice only such as describe some improvement in the modes of culture, or some extension of the practices that were formerly little known.

In John Houghton’s Collections on Husbandry and Trade, a periodical work begun in 1681, there is one of the earliest notices of turnips being eaten by sheep:—“Some in Essex have their fallow after turnips, which feed their sheep in winter, by which means the turnips are scooped, and so made capable to hold dews and rain water, which, by corrupting, imbibes the nitre of the air, and when the shell breaks it runs about and fertilizes. By feeding the sheep, the land is dunged as if it had been folded; and those turnips, though few or none be carried off for human use, are a very excellent improvement, nay, some reckon it so, though they only plough the turnips in without feeding.” This was written in February 1694. Ten years before, John Worlidge, one of his correspondents, and the author of the Systema Agriculturae (1669), observes, “Sheep fatten very well on turnips, which prove an excellent nourishment for them in hard winters when fodder is scarce; for they will not only eat the greens, but feed on the roots in the ground, and scoop them hollow even to the very skin. Ten acres (he adds) sown with clover, turnips, &c., will feed as many sheep as one hundred acres thereof would before have done.”

The next writer of note is John Mortimer, whose Whole Art of Husbandry, a regular, systematic work of considerable merit, was published in 1707.

From the third edition of Hartlib’s Legacie we learn that clover was cut green and given to cattle; and it appears that this practice of soiling, as it is now called, had become very common about the beginning of the 18th century, wherever clover was cultivated. Rye-grass was now sown along with it. Turnips were hand-hoed and extensively employed in feeding sheep and cattle.

The first considerable improvement in the practice of that period was introduced by Jethro Tull, a gentleman of Berkshire, who about the year 1701 invented the drill, and whose Horse-hoeing Husbandry, published in 1731, exhibits the first decided step in advance upon the principles and practices of his predecessors. Not contented with a careful attention to details, Tull set himself, with admirable skill and perseverance, to investigate the growth of plants, and thus to arrive at a knowledge of the principles by which the cultivation of field-crops should be regulated. Having arrived at the conclusion that the food of plants consists of minute particles of earth taken up by their rootlets, it followed that the more thoroughly the soil in which they grew was disintegrated, the more abundant would be the “pasture” (as he called it) to which their fibres would have access. He was thus led to adopt that system of sowing his crops in rows or drills, so wide apart as to admit of tillage of the intervals, both by ploughing and hoeing, being continued until they had well-nigh arrived at maturity. Such reliance did he place in the pulverization of the soil that he grew as many as thirteen crops of wheat on the same field without manure.

As the distance between his rows appeared much greater than was necessary for the range of the roots of the plants, he begins by showing that these roots extend much farther than is commonly believed, and then proceeds to inquire into the nature of their food. After examining several hypotheses, he decides this to be fine particles of earth. The chief and almost the only use of dung, he thinks, is to divide the earth, to dissolve “this terrestrial matter, which affords nutriment to the mouths of vegetable roots”; and this can be done more completely by tillage. It is therefore necessary not only to pulverize the soil by repeated ploughings before it be seeded, but, as it becomes gradually more and more compressed afterwards, recourse must be had to tillage while the plants are growing; and this is hoeing, which also destroys the weeds that would deprive the plants of their nourishment.

The leading features of Tull’s husbandry are his practice of laying the land into narrow ridges of 5 or 6 ft., and upon the middle of these drilling one, two, or three rows, distant from one another about 7 in. when there were three, and 10 in. when only two. The distance of the plants on one ridge from those on the contiguous one he called an interval; the distance between the rows on the same ridge, a space or partition; the former was stirred repeatedly by the horse-hoe, the latter by the hand-hoe.

“Hoeing,” he says, “may be divided into deep, which is our horse-hoeing; and shallow, which is the English hand-hoeing; and also the shallow horse-hoeing used in some places betwixt rows, where the intervals are very narrow, as 16 or 18 inches. This is but an imitation of the hand-hoe, or a succenadeum to it, and can neither supply the use of dung nor fallow, and may be properly called scratch-hoeing.” But in his mode of forming ridges his practice seems to have been original; his implements, especially his drill, display much ingenuity; and his claim to the title of founder of the present horse-hoeing husbandry of Great Britain seems indisputable.

Contemporary with Tull was Charles, 2nd Viscount Townshend, a typical representative of the large landowners to whom the strides made by agriculture in the 18th century were due. The class to which he belonged was the only one which could afford to initiate improvements. The bulk of the land was still farmed by small tenants on the old common-field system, which made it impossible for the individual to adopt a new crop rotation and hindered innovation of every kind. On the other hand, the small farmers who occupied separated holdings were deterred from improving by the fear of a rise in rent. Townshend’s belief in the growing of turnips gained him the nickname of “Turnip Townshend.” In their cultivation he adopted Tull’s practice of drilling and horse-hoeing, and he was also the founder of the Norfolk or four-course system, the first of those rotations which dispense with the necessity of a summer-fallow and provide winter-keep for live-stock (see below, Rotation of Crops). The spread of these principles in Norfolk made it, according to Arthur Young (writing in 1770), one of the best cultivated counties in England. In the latter half of the century another Norfolk farmer, Thomas William Coke of Holkham, earl of Leicester,
