the air turn green and are not edible, but poi- 

 sonous. Early or new potatoes may be dug 

 and separated from the vine without killing 

 the plant or retarding its growth. Take off 

 two or three of the largest and cover up the 

 hole. 



The crop of old potatoes, as the ripe tubers 

 are called, are gathered after the tops die 

 down, by digging or plowing up the hills. They 

 may be left in the ground for several weeks 

 and dug as wanted. Dig them all before first 

 rain. Let the potatoes lie in the sun for a few 

 hours to dry before gathering. 



More pounds of potatoes are produced than 

 any other food crop in the world. 



Potato Scab. 

 Is much in evidence in potato crops each 

 year. To keep it under control the seed should 

 first be dipped in some disinfecting solution. 

 Two kinds are used, the formaldehyde and 

 corrosive sublimate solution. The formalde- 

 hyde is prepared by pouring a pint of formal- 

 dehyde into 30 gallons of water. Dip the po- 

 tato seed in this for two hours, covering the 

 barrel. Potatoes must be planted soon after 

 dipping or spread out in the sun to dry.
