produced an equal bulk. Of the same number planted on 

 April 30, 13 again were in excess of those planted on May 31, 

 and one (White Elephant) less. Of the twelve varieties planted 

 on May 31 and June 14, the whole 12 planted on the earlier 

 date yielded more than those planted later, and the whole of 

 the 10 varieties planted respectively on June 14 and June 28 

 yielded more on the first than on the second planting. So, in 

 comparing these fifty instances of an earlier with the next 

 succeeding planting, we find that no less than 48 yielded 

 heavier crops, one an equally heavy crop, and only one a less 

 crop the weight including both seed and ware. 



That the date of the last planting, June 28, was backward 

 enough was proved by the very poor result obtained, the 

 average weight for the whole lot being very little over 26 cwt. 

 per acre, or not twice the weight of the seed originally planted. 

 In some cases, notably those of The Bruce, Magnum Bonum, 

 and Imperator, they never grew with sufficient vigour to pre- 

 vent their ripening before those planted a fortnight earlier. 

 We find that the average weight per acre of those planted on 

 March 31 was about 19 cwt. in excess of those planted a month 

 later, 46.^ cwt. above those planted on May 31, 69i cwt. more 

 than those planted on June 14, and no less than 105 cwt. in 

 excess of those planted last of all. Putting their average value, 

 one season with another, at the somewhat low figure of 50s. per 

 ton, the first planted exceeded in value the second by 2 7s. 6d., 

 the third by 5 16s. 3d., and the fourth by 13 2s. 6d. per acre. 



It is often more or less impracticable to commence planting 

 largely before the latter end of March, but these results point em- 

 phatically to the necessity of getting the potatoes (particularly 

 the earlier varieties) in by the end of April, for though the 

 falling-off of 19 cwt. per acre is considerable, yet up to that 

 time there is still a prospect of tolerably good yields ; but the 

 further fall to 46^ cwt. of those planted on May 31 puts out of 

 the question all idea of a profit from those planted so late in
