Blith's books on husbandry show notable good sense, based on the author's and others' farming experience. He presents his judgements and opinions carefully, and made textual changes in subsequent editions to describe new farming practices. His The English Improver, or, A New Survey of Husbandry was dedicated to both houses of Parliament and to the "ingenuous reader". A second edition appeared in the same year, and third, "much augmented" in 1652, with a second part containing "Six Newer Pieces of Improvement". This was dedicated to Cromwell, the council of state, nobility, gentry, soldiers, husbandmen, cottagers, labourers, and the meanest commoner. The new information concerned new crops such as woad, clover, sainfoin, lucerne, etc. Yet another edition appeared in 1653. Blith intended to write a further book on animal husbandry, but apparently did not complete it. His Parliamentarian sympathies prevented any of his work reappearing after the Restoration of 1660. The books were written "in our own natural country language and in our ordinary and usual home-spun terms". He urged agricultural improvement, but showed less enthusiasm for enclosure, through his concern for the poor: enclosure should not be allowed to cause depopulation. Blith's views almost certainly reflect discussion with Joseph Lee, the pamphleteer and advocate of enclosure, who was rector of Cotesbach. Enclosure had in fact caused turmoil in the village in 1603 and made it a centre of the Midland revolt of 1607. Though Blith showed sympathy for the common man and understood the aspirations of the Diggers, he did not think the latter were realistic. Blith's work also bore a religious message, holding up "the examples of biblical husbandmen and improvers, from Adam to Solomon, as well as that of God himself, 'the great Husbandman', who had first made plants and trees come forth upon the earth. God intended the preservation of his creation, Blith suggested, and mankind was the instrument by which he would achieve this. For Blith, therefore, the historical examples of the Bible taught the lesson that individuals had a duty to God to practise a reformed husbandry, and that only by doing this might their country be redeemed from sin, famine, and warfare into a new Eden of peace and plenty. Blith's ideas brought some improvement in techniques, but the period of peace under the Commonwealth was short-lived, and general, substantial improvement had to wait for the Agricultural Revolution of the next century.
