so all over the neighborhood, for it is the reverse with some of our 

 neighbors. 



Mr. Moffat, of the same county gives a clue to some of these 

 contradictions. He says, " The kind of potato that is least affected 

 on the heavy soil, is more affected on the light soil, so far as the 

 disease has shown itself on both kinds of soils. The cup potato is 

 less affected on the heavy land with me than the red potato is. In 

 a farm adjoining, where the land is light, the cup potato is much 

 Uiore affected than the red one is." 



Mr. Gardiner, overseer to Mr. Fleming, of Barochan, gives a 

 similar instance. As a general rule, the cups and coarser potatoes, 

 seem to have been least affected, and in many cases to have been 

 later in showing the disease. Neither does it appear that changing 

 the seed is a protection, the kinds recently introduced have been in 

 some instances less affected, but in others /ctr more. This brings us 

 to the ninth query. 



Query 9. — Are varieties raised from seed, or such asbearno apples, 

 to your knowledge liable to failure. 



All who have read the publications upon the potato disease, will 

 have noticed that great stress has been laid upon the necessity of 

 producing new varieties from the seed, to replace those whose con- 

 stitutions are injured by long cultivation. In fact this has been by- 

 some upheld as a certain remedy for the disease. It is most unfor- 

 tunate for those who believe this, that in the whole of the answers 

 to the abt)ve question, there is not one favorable to their theory. 



Mr. Girdwood says, " I have ten sorts raised from seed two years 

 ago, all affected." 



Mr. J. McBride, Wigfonshire: "I know of varieties that were 

 recently grown from the seed of sound and healthy potatoes that 

 have been worse than any other kind. With myself they have been 

 an entire failure." 



Mr. Kennedy^ Wigtonshire: "I use all varieties, the recently in- 

 troduced have failed first, and the older ones followed. 



Mr. Gardiner: " Varieties raised from seed are as liable to failure 

 and disease as any of the older varieties. Above sixty varieties 

 raised from seed, upon this farm, one, two and three years ago, and 

 planted this spring, have been attacked by this disease with as much,
