In the following table particulars are given of the crops of potatoes obtained each 

 year from 1894 to 1897, inclusive, from each of the plots devoted to experiments with 

 fertilizers, also the average results of these tests for four years. It will be seen that 

 plot 1, to which well rotted barn-yard manure has been applied, has given the best 

 results in the plots after barley, while in those after wheat plot 2 on which fresh manure 

 was used, has a very slight advantage. None of the artificial fertilizers or mixtures of 

 these fertilizers have given results as good as those obtained from barn-yard manure. 

 Of the single fertilizers tried, the best crops have been had from the Mineral Superphos- 

 phate of lime, and tliie next best from Muriate of Potash.
