Clearly demonstrated from principles of sound reason, ingenuity, and late, but most certaine reall experiences. Held forth under six peeces of improvement. Viz. 1. By floating or watering such lands as are capable thereof. 2. By reducing boggy or drowned land to sound pasture. 3. By such a way of ploughing and corneing old courser pasture, as not to impoverish it; and by such a method of enclosure, as shall provide for poore. And all interests without depopulation. 4. By discovering divers materials for soyle and compost, with the nature and use of them, as both tillage and pasture be advanced as high as promised. 5. By such a new plantation of divers
