He took to agriculture more by necessity than by choice, for he knew too much 'the inconveniency and slavery attending the exorbitant power of husbandry servants', and he further gives this extraordinary character of the farm labourer of his day: ''Tis the most formidable objection against our agriculture that the defection of labourers is such that few gentlemen can keep their land in their own hands, but let them for a little to tenants who can bear to be insulted, assaulted, kicked, cuffed, and Bridewelled, with more patience than gentlemen are endowed with.'[411] Tull wrote just before it became the fashion for gentlemen to go into farming, and laments that the lands of the country were all, or mostly, in the hands of rack-renters, whose supposed interest it was that they should never be improved for fear of fines and increased rents. Gentlemen then knew so little of farming that they were unable to manage their estates. No doubt his scathing remarks helped to initiate the well-known change in this respect, and soon, over all England, gentlemen of education and position were engaged in removing this reproach from their class. The same complaint as to their ignorance of matters connected with their land crops up again during the great French war, but they then had a good excuse, as they were busy fighting the French. Tull invented his drill about 1701 at Howberry. The first occasion for making it, he says, was that it 'was very difficult to find a man that could sow clover tolerably; they had a habit to throw it once with the hand to two large strides and go twice in each cast; thus, with 9 or 10 lb. of seed to an acre, two-thirds of the ground was unplanted. To remedy this I made a hopper, to be drawn by a boy, that planted an acre sufficiently with 6 lb. of seed; but when I added to this hopper an exceeding light plough that made 6 channels eight inches asunder, into which 2 lb. to an acre being drilled the ground was as well planted. This drill was easily drawn by a man, and sometimes by a boy.' His invention was largely prompted by his desire to do without the insolent farm servant whom he has described above, and the year after it was invented he certainly had his wish, for they struck in a body and were dismissed: 'it were more easy to teach the beasts of the field than to drive the ploughman out of his way.'
