155 



TABLE LIX. Percentages of Gramineous, Leguminous, and Miscellaneous 

 Herbage. Average of determinations made at different times during 

 57 years (1856-1912, and 1902 separately}.^ Rothamsted. First crops. 



Including Potash, first 6 years. 



t The hay from some plots is partially separated nearly every year, but that 

 from others is only analysed at irregular intervals as occasion arises. Conse- 

 quently the averages in the above table refer to a different number and selection 

 of years for each individual plot, according to the analyses that have been made.
