The company began operations in February 1902, and the 

 actual output at the present time is stated to be 600 barrels a 

 day, but additional machinery is being put in, so that by Dec. 1, 

 1902, its capacity is expected to reach 1000 barrels a day. The 

 method of manufacture consists of gradually reducing the raw 

 materials in large crushers, Griffin mills, or tube mills; the burn- 

 ing is done in rotary kilns, and the clinker is ground in Griffin 

 mills and tube inilis.
