11. Amber—October 2, 1880. Juice obtained from the upper half of the stalks after topping as usual. Specific gravity 1.069 Grape sugar 2.94 per cent. Cane sugar 9.67 " 12. Amber—October 2, 1880. Juice obtained from the lower half of stalks. Specific gravity Grape sugar Cane sugar. 1.070 1.94 per cent. 11.64 "

13. Orange—October 6, 1880. Juice obtained from plants very ripe, stalks still standing in the field. No appearance of injury by the slight frost of the previous week. Specific gravity 1.078 Grape sugar 4.02 per cent. Cane sugar 11.41 " Weight of entire stalks taken . 3 / pounds.

Orange—Oct. 23, 1880. Juice obtained from cane which was cut, stripped and topped Oct. 2, and placed under shelter until examined. Juice whitish. Specific gravity .'. 1.094 Grape sugar 14.66 per cent. Cane 3.55 The acidity of the juices was tested from time to time. The juice of the amber was more acid in every instance than that of the orange. Each variety reached its minimum of acidity at the maximum of cane sugar, and its maximum acidity by standing after being cut. The temperature in these experiments was 2u° C.
