tion of steam and chemicals, the time being three 
to four hours as compared with eight to twelve 
hours for wood pulp. 
The most serious disadvantage is the limited pro- 
duction of the raw material, the total of which does 
not amount to more than 1,000 tons for the entire 
United States. 
The stalks when extracted for an hour under steam 
pressure, yield a quantity of soluble solids which 
contain practically all of the food value of the raw 
material. These tests indicate that if they can be 
secured in sufficiently large quantities, the broom- 
corn stalks can be pulped at a profit without taking 
into consideration the value of the food extract.
