 wood, coal and limestone, with earth as a 

 covering. Dr. Wm. Frear, chemist of the 

 Pennsylvania station, in Bulletin 261 of the 

 Pennsylvania department of agriculture, 

 describes a method of burning lime on the 

 farm as follows: "A convenient oblong

 need be, to secure a fit platform. Upon this

 near each end, and the stone and coal are
