GiLLIEs.—On Sorghum Haperiments. 515 
concentrated syrup weighs 144 lbs. to the gallon, it would, if sold at the 
absurdly low price of 1d. per lb. (in America it sells for 7 cents. per 1b.— 
or 834.), produce a gross return of £14 10s. per acre, a sum sufficient to 
yield a fair profit per acre; as I calculate that with a two-horse mill crush- 
ing 80 gallons of juice, or 1 ton of cane per hour, the total expense of 
crushing and evaporating should not cost, (within reasonable distance of 
coal,) over 10s. per ton, or £6 per acre. This is, of course, only calculation, 
as the actual cost in my experiments, employing special labour, came to 
about £1 per ton, or £16 per acre. But even this would leave a good profit 
with syrup at 2d. per lb. On a farm no labour would be required other 
than the ordinary labour of the farm, and the leaves and seed would be an 
important and valuable item in the feeding of stock and poultry. 
I have now finished my experiments, as my increasing public duties will 
prevent my further prosecuting them. It remains for some intelligent 
farmer to take up the matter, and test the results I have obtained. To 
such an one I shall be happy to hand over my crushing-mill, boiler, and 
other apparatus, as well as afford him every advice and assistance in my 
power. I feel thoroughly convinced that, at no distant date, the growth of 
Sorghum will be found to be one of the most paying crops that the northern 
farmer can produce. 
Supplementary Paper on Sorghum. By Mr. Justice Gus. 
i [Read before the Auckland Institute, 17th September, 1883.] 
Since reading my paper on Sorghum at last meeting I have received from 
Dr. Hector the results of the Colonial Laboratory analysis of a one gallon 
jar of syrup sent him some four months after it was made. These results 
and the data they afford as to the commercial value of growing Sorghum 
for sugar production are of the utmost value. The following is the 
report :—

At a temperature of 60°, specific gravity 1-406 water at 1:000, the syrup contained 
71:60 per cent. of cane sugar. The syrup and sugar gave 7:15 per cent. of 
grape sugar.
