 purpose. There is a form of it which has taller stems, leaves 

 slightly reticulated, and 

 numerous white flowers, and 

 which resembles the Royal 

 Ash-leaf Kidney. This, al- 

 though not so early, is far 

 more productive than the 

 ordinary variety. It is grown 

 in the open air. About 

 Paris, the practice of sprout- 

 ing " seed " potatoes before 

 planting them is very 

 common. For this purpose, 

 the tubers are ranged on 

 wicker-work screens (care 

 being taken to place them 

 with an eye uppermost), and

 from frost until they are 

 planted. When planting- 

 time arrives, the screens are carried to the ground, and the 

 tubers are taken from them one by one and carefully deposited

 mishap which occurs 

 more frequently with this 

 variety than with any 

 other — that is, the com-

 overground stems. When 

 this happens, no stems
