Dilution of the Sugar Cane Juice. 73 
cents net value of sugar minus 27 cents cost of coal 
equals 36 cents profit on every 10,000 lbs. of canes or 
$077 on every ton of sugar. If the water is added after 
the megass has passed the second mill and 77 0/0 of 
juice has been extracted, we find that it is necessary to 
add 148 lbs. of water in order to reduce the juice to 
8 deg. Beaume. By a calculation similar to the preced- 
ing one we obtain a profit of $1*05 per ton of sugar. 
The table on page 75 shows the composition of the 
megass after the juice it contains has been reduced to 
8 deg B., 7 deg. B., etc., also the profit or loss per ton 
of sugar when the water is added to the megass after 
60 per cent, and 77 per cent, juice have been extracted. 
From this table it appears that when water or steam is 
added after the megass has left the first mill and the 
crushing is about 60 per cent, the greatest profit is 
derived by reducing the juice extracted by the second 
mill to 6 deg. Beaume. If the juice be reduced to 7 deg. 
Beaume a gain of $1 07 is obtained, which is only 9 
cents less than the profit obtained by reducing the 
juice to 6 deg, Beaume. Taking into consideration the 
first cost and wear and tear of the evaporating machin- 
ery, it is evident that with our present appliances it 
will only pay to reduce the density of the juice to 7 deg. 
Beaume. If the water be added to the megass after it 
leaves the second mill and 77 per cent, of the weight of 
the canes has been obtained in juice, and the extra juice 
is separated by means of a third mill, centrifugal or 
press, it appears from the table that the greatest profit 
is obtained by reducing the juice to 5 deg. Beaume. By 
still further reducing the juice, the quantity of coal 
required to evaporate the extra water causes the profit
