In examining this tabulation it will be well at first 

 to confine attention to Series 1, and which is seen to 

 consist of three experiments, as follows ;— 



No. 1. Unmanured . . . . , -i 



p. 



No. 2. Manured with 20 bushs. of clay and wood I „„ 

 ashes, and of these the produce is united ( 

 and thrown into one mean of J 



No. 3. Manured with 14 tons of farm-yard manure 43 







Of 



And the object for which these trials were instituted, 

 and the results classed together, is expressed by the ex- 

 perimenters in the following words, " The mean result 

 of the unmamired and ash portions, taken together, 

 form one, and that of the farm-yard manure another 

 standard of com2)arison by which to judge of the effects 

 of the other manures."— V. 481.
