Some farmers obtained land grants to create farms in undeveloped land in Massachusetts and Connecticut or bought plots of land from speculators in New Hampshire and what later became Vermont. Other farmers became agricultural innovators. They planted nutritious English grass such as red clover and timothy-grass, which provided more feed for livestock, and potatoes, which provided a high production rate that was an advantage for small farms. Families increased their productivity by exchanging goods and labor with each other. They lent livestock and grazing land to one another and worked together to spin yarn, sew quilts, and shuck corn. Migration, agricultural innovation, and economic cooperation were creative measures that preserved New England's yeoman society until the 19th century.
