RESULTS OF GERMINATION TESTS OF GRAIN IMMERSED FROM 



ONE TO FOURTEEN MINUTES IN THE VARIOUS 



FORMALIN SOLUTIONS.

Table XX. — Continued. 



Note: The symbols S. W. D. stand for strong, weak and dead. 



It will be noted from the above table that the stronger solu- 

 tions have a marked influence on the vitality of the oats. For 

 all solutions below one to thirty the danger resulting from im- 

 mersing is apparent. Even immersing for one minute in those 

 solutions caused more injury than the use of eight pints per 

 bushel of the one to ten solution and covering for two hours. 

 Di] ping grain in the solution of one to thirty and one to forty 

 caused no apparent injury, and for practical purposes these 

 may be recommended.
