290 APPENDIX. 
Before passing to the economic part of our subject, we will speak 
of some special products furnished by the sugar sorgho. The researches 
of many intelligent observers have evinced in this plant certain 
coloring principles, susceptible of acquiring a certain importance that 
is very likely, so far as regards the hull of the seed; but as to the 
stalk, it is not possible to hope it having a good result in practice. 
But in advancing this opinion we hope that we will not be understood 
as being hypercritical upon the scientific laborers who, analyzing 
matter, have extracted from it its most hidden secrets; thus again 
proving that man, thanks to the sources of his intelligence, finds in 
everything a part worthy of his attention, and that he has only to 
interrogate to obtain all he needs; that, in a word, there is nothing 
in the whole realm of nature which is entirely without valne. We 
may repeat the preceding remarks in considering the cerosie, a waxy 
efflorescence which is met with upon some large cereals, the obtain- 
‘ment of which is not more possible in the case of the sorgho than with 
the sugar cane; nevertheless, it is a substance which merits being 
studied, and it is necessary to know it more intimately to follow it 
through the different elaborations which it undergoes in the saccharine 
stalk. 
EXPENSES AND PROFITS OF THE INDUSTRIAL CULTURE OF THE 
SORGHO. ' 
In the following table we have not the pretension to fix in a peremp- 
tory manner, a result which the sorgho may give under all circum- 
stances. We wish only to present the probable results of a good 
culture, with a soil suitable to its growth, and endowed with certain 
fertility. 
RAW PRODUCT. 
1. Sixteen thousand pounds of stalks, which, treated by 
maceration, will yield at least seventeen gallons of juice to - 
two hundred and seventy pounds, say ten thousand three 
hundred gallons of juice, susceptible of giving eight per 
cent. of alcohol (in the south of France and in Algeria ; 
seven and six per cent. in our central departments) upon 
distillation. This, then, is a yield of about eight hundred
