POTATO CULTURE. 79 



same L on the ripe potato. He says we must bear in mind 

 the effort always made by a living tissue to heal a wound, 

 in order to understand the form the scabs assume. The 

 ultimate form is the result of a continuous formation of 

 layers of cork below the area of disease, because of the irri- 

 tating, eroding action of the parasite. It seems as though 

 this action must stop as soon as growth is over. If so, some 

 growers are greatly mistaken. For example, one market- 

 gardener told me he always dug his Early Ohio potatoes the 

 moment they were done growing, as, if left in the soil till 

 fall, they would be a mass of scabs. 



Later. I have just got from friend Boot 25 new bushel 

 boxes to handle my seed in this year, after treating it. I 

 think it will be advisable to go to the trouble of treating it. 

 There may be some germs on my own or purchased seed, no 

 matter how nice the tubers may look. I have just bought 

 12 oz. of corrosive sublimate also, for $1.50.
