Tow and flax are such bad conductors of heat, 

 that a piece of ice will be preserved a long time

 of this to be mixed thoroughly with 16 ounces of 

 the butter as soon as it is freed from the* butter 

 milk; it is then to be put into a close and perfect-

 carefully excluded, and it will remain good for 

 many years

The soils most suited to the culture of this 

 plant, are those of the deep, black, putrid, veget-

 is generally much greater on the former than on 

 the latter; but it is said to be greatly inferior in
