TABLE No, 17. Diffusion juice. 



The system of diffusion employed at Ilio Grande is fully explained 

 by 'Fig. 5, Bulletin No. 17. It differs radically from the system of 

 closed diffusion. As operated at Bio Grande last year the extraction 

 was no better than by good milling in Louisiana, while the dilution was 

 fully as great as at Fort Scott and Magnolia. 



The defects of the system were both mechanical and chemical.
