POTATOES — TESTING ADVISABILITY OF PLANTING AS SOON AS CUT. 



British Queen potatoes were planted the same day the seed was cut, but a part of 

 the seed was held over for two weeks and planted on the rows adjoining those of the 

 same variety planted two weeks previous. The held seed was stored in sacks in a 

 fairly light room.
