It is usually made in a small way with mills driven by a horse or mule and with primitive methods of evaporation in an ordinary kettle. Hard pine wood is burned for the evaporation and the empyreumatic flavor of the pine is often absorbed by the sirup. In Figs. 80 and 81 are shown typical apparatus used for the manufacture of sirup from sugar cane in Georgia and in Fig. 82 the relative length of canes ready for manufacture. In factories where modern apparatus is used,
