560 Experiments on the Potato- Crop. 



The rate of progression was found to be very regular, both in 

 individual experiments, and in average results. 



Sixthly. As to the relative pjvditctiveness of different varieties 



of the Potato. 



To avoid undue complication, the varieties employed in these 

 experiments have been rather limited, and the question of their 

 relative productiveness has only been a matter of secondary im- 

 portance. As, however, several of the varieties are very generally 

 cultivated, it may be well briefly to state the results. 



The average produce of 1 oz., 2 oz., and 4 oz. sets planted 

 1 foot apart in the rows was as follows on the gross crop per 

 acre : —
