When a litre of sap of the sugar sorgho weighs 1064 grammes, 
a.sout 9° Beaumé, a gallon of this same sap weighs 4 kilogrammes 0°31 
grammes, or 8 Ibs. 14 oz. 2 drachms 14 grains, English weight. This 
gallon of sap contains 652 grammes of sugar, salts, and organic mat- 
ters, or 1 lb. 7 oz. 4 gr , English weight.

To make one thousand lbs. of unrefined sugar, cleansed and well 
dropped, with sap of the sorgho of a density of 1064, requires 1250 
to 1300 gallons of sap. This sugar is of the same kind as that ex- 
tracted from the cane. 
The sugar of the sorgho will give almost as much molasses as the 
cane sugar in Louisiana, perhaps a little less, because it has a density 
a trifle more than the average of the cane in Louisiana, at least that 
which I have examined. 
One thousand pounds of this sugar thoroughly clarified, will not 
give less than fifty-five gallons of molasses ; in some instances the molasses 
would be in much greater proportion. In this respect the sorgho will 
share the vicissitudes of the sugar cane—sueceeding years would not 
give equal results, 
An arpent (six sevenths of an acre) of sorgho, well cultivated, with 
~a good yield, might give eight hundred to one thousand Ibs. of raw 
sugar, clarified and saleable. The experiments which I have made 
upon the subject show this clearly enough. Certainly the sorgho cannot 
supersede the sugar cane in Louisiana; but it has great advantage 
over the cane, in that it can be crushed from the early part of August, 
and throughout September, whilst the cane cannot be crushed until 
about the first of November. It remains to be known if this ad- 
vantage can reconcile itself with the other interests of the planter ; 
this I have not sought to establish. 
The sap of the, sorgho, after having been clarified, as do all the
