The actual weight of tubers thus raised from 21 seeds was 

 44 lbs. 8^ oz., discarding all fractions, say upon an average 2 lbs. 

 of healthy tubers to each plant. The number of plants thus 

 raised per acre would be 7260, which multiplied by 2, the aver- 

 age weight of the produce of each of the plants will give 

 14,520 lbs. = 6 tons 9 cwt. an acre, or taking the sack at 2J cwt. 

 to 5H sacks per acre.
