on Table 9 the three normal leaves above from plot 5, with the eight belov^^ from 

 the Potash -deficient plot 6.) 



The individual leaflets assume a crimpled form similar to those of the Tobacco 

 plant, — also the mid -rib turns invv'ards towards the under surface — the leaves 

 retain an undulating appearance and yellowish spots which gradually turn brown 

 show between the veins of the leaf, drying up finally dark brown without inter- 

 mediate yellow. 



Such alterations are not exhibited by leaves of normally nourished potato plants. 

 These turn yellow-green to yellow before ripening, and this without any alteration 

 of the leaf form, and finally dry up brown, which is, however, lighter than when 

 Potash is lacking. 



Crop of fresh tubers from 1 acre.
