“ New pine tubs are ruinous to the butter. To have sweet butter in dog days, and thro' the vegetable seasons, send stone pots to honest, neat, and trusty dairy people, and procure it pack'd down in May, and let them be brought in in the night, or cool rainy morning, covered with a clean cloth wet in cold water, and partake of no heat from the horse, and set the pots in the coldest part of your cellar, or in the ice house.—Some say that May butter thus preserved, will go into the winter use, better than fall made butter. ”
