distilled in Ceylon and elsewhere from the leaves of this 
species. General Martin observed, that cattle are vora- 
ciously fond of this grass ; but it imparts its fragrance to

Andropogon saccharatus, Eoxb. {Sorghum saccharatum, Pers.) 
Tropical Asia. The Broom-Corn. A tall annnal species, 
splendid as a fodder grass. Erom the saccharine juice 
sugar is obtainable. A sample of such, prepared from plants 
of the Melbourne Botanic G-arden, was shown at the 
Exhibition of 1862. This Sorghum furnishes also material 
for a well-known kind of brooms. A variety or a closely 
allied species yields the Caffir Corn {A. Gaffrorum, Kunth). 
The plant can be advantageously utilized for preparing 
treacle. For this purpose, the sap is expressed at the time 
of flowering, and simply evaporated ; the yield is about 
100 gallons from the acre. In 1860, nearly seven millions 
of gallons of sorghum treacle were produced in the United 
States.
