556 Experiments on the Potato-Crop. 



Secondly. As to the influence on the crop of the distance at which 

 the sets are planted ; or the results of close and wide plantinrj of 

 various sized sets. 



To establish this point, I shall compare, separately, each series 

 of experiments on potatoes of the same weight, planted at different 

 distances : — 



Averages of 1 oz. Sets. 



These comparisons all shew an advantage in planting the 

 smaller sets at intervals closer than 12 inches in the rows ; but 

 the results are not very decided, and in one or two cases the 

 gain in the gross crop does not make up for the extra weight of 

 the sets planted. 



The following comparisons refer to the effect of planting the 

 sets more than a foot apart in the rows. 



Three experiments averaged together, viz. — 



8 oz. "Flukes," 6 oz. "Flukes," and 4oz. "Late Red," gave 

 a gross crop of 23 tons 16 cwts. 1 qr. 8 lbs., and a net average 

 of 20 tons 3 cwts. 1 qr. 17 lbs. The same sizes and varieties, 

 planted at intervals in the rows of 1 foot 3 inches, produced a 

 gross crop of 18 tons 13 cwts. 1 qr. 2 lbs., and a net crop of 

 15 tons 14 cwts. 3 qrs. 20 lbs. — a falling off of 4 tons 8 cwts. 

 1 qr. 25 lbs. per acre. Indeed the produce of each set was, as 

 nearly as possible, the same, whether planted a foot apart or 

 15 inches, so that the additional distance was so much loss to 

 the crop. The average produce of 6 oz. and 8 oz. Flukes shews
