much more than fully ripe, the hay having shed its seed, and 

 being quite dry and hard. The results are contained in the 



following table 



Table IV. — Field Plan of Experiments on Hay, showing the 

 arrangement of the plots, and the produce in pounds of the 

 hay moiun on the 11th September. 



The field on which this experiment was made had a con- 

 siderable slope, and, as often happens in that case, the quality 

 of the soil was not uniform. The Nothing plots indicate very 

 distinctly the increase in the produce from above downwards, 

 but the arrangement is such that the duplicate results correct 

 one another, the produce of one plot from each manure being 

 as much above the average as the other is below it. This is 

 obvious from the next table, which gives the results per acre, 

 and in which, owing to the size of plot adopted, the numbers 

 which stand for lbs. in the field plan represent cwts.
