There was a great increase in the number of live stock owing to the spread, gradual though it was, of roots and clover, which increased the winter food; 'of late years,' it was said in 1739, 'there have been improvements made in the breed of sheep by changing of rams, and sowing of turnips, grass seeds, &c.'[375] Crops, too, were improving; and enclosed lands about 1726 were said to produce over 20 bushels of wheat to the acre.[376] Though the number of Enclosure Acts at the beginning of the century was nothing like the number at the end, the process was steadily going on, often by non-parliamentary enclosure, and was approved by nearly every one. Some, however, were opposed to it. John Cowper, who wrote an essay on 'Enclosing Commons' in 1732, said, a common was often the chief support of forty or fifty poor families, and even though their rights were bought out they were under the necessity of leaving their old homes, for their occupation was gone; but he says nothing of the well-known increased demand for labour on the enclosed lands. The force of his arguments may be gauged from his answer to Lawrence's statement that enclosure is the greatest benefit to good husbandry, and a remedy for idleness. On the contrary, says he, who among the country people live lazier lives than the grazier and the dairyman? All the dairyman has to do is to call his cows together to be milked! Worlidge in 1669 had lamented that turnips were so little grown by English farmers in the field, and that it was a plant 'usually nourished in gardens',[377] and in a letter to Houghton in 1684, he is the first to mention the feeding of turnips to sheep.[378] However, in 1726 it was said that nothing of late years had turned to greater profit to the farmer, who now found it one of his chief treasures; and there were then three sorts: the round which was most common, the yellow, and the long.[379] For winter use they were to be sown from the beginning of June to the middle of August, on fallow which had been brought to a good tilth, the seed harrowed in with a bush harrow, and if necessary rolled. When the plants had two or three leaves each they were to be hoed out, leaving them five or six inches apart, though some slovenly farmers did not trouble to do this; but there is no mention of hoeing between the rows. The fly was already recognized as a pest, and soot and common salt were used to fight it. Folding sheep in winter on turnips was then little practised, though Lawrence strongly recommends it. According to Defoe,[380] Suffolk was remarkable for being the first county where the feeding and fattening of sheep and other cattle with turnips was first practised in England, to the great improvement of the land, 'whence', he says, 'the practice is spread over most of the east and south, to the great enriching of farmers and increase of fat cattle.' There were great disputes as to collecting the tithe, always a sore subject, on turnips; and the
