“ Another Watsonville man who lives two miles from 
the factory and cultivated eleven acres, reports a yield of 
170 1-20 tons, which netted him a profit of $35.08 per 
acre.’’ 
When we were at Grand Island we learned that the 
plant there cost about $500,000. About 200 men are 
employed, 100 on each shift, running night and day. 
There are six batteries of boilers, two in each battery. We 
noticed that they made their own lime on the ground. 
They used up about 250 tons of beets a day. It was about 
11a. m. when we visited the packing rooms, and the work¬ 
men told us that they put up 110 sacks (100 pounds in a 
sack) that morning, or, at that rate, about 400 sacks of 
sugar a day. The plant runs as long as there are beets to 
be had—sav from three to five months. 
It is apparent from the numerous inquiries about 
sugar b’eets, that a great many farmers do not understand 
the terms used by chemists and others in describing the 
work. This may be due to the fact that the previous 
bulletins (Nos. 7 and 11) have not fallen tnto their hands. 
We find it necessary, even at the cost of repetition, to 
explain the terms used : 
Coefficient of Purity —Is the term used to denote the 
ratio per cent, of the total sugar (sucrose) in the juice to 
the total solids. Suppose, for instance, that the juice con¬ 
tained 15 per cent, total solid and 11 per cent, sugar 
(sucrose), the coefficient of purity would be 11 —f- 15 = 
73.3 per cent. It must follow that the higher the coeffi¬ 
cient of purity the easier it is for the manufacturer to 
make the sugar from the juice of the beet. 
Marc —Is the name applied to the dried residue or 
chips that remain after the sugar and juice have been 
extracted. It is used to some extent as a cattle food, and 
sold in Grand Island, Nebraska, at twenty-five cents a ton.
