broken up grass lands as commonly as on any other description of 

 lands." 



I have before me no less than thirteen other answers which say 

 essentially the same thing. In a few instances, those grown on 

 newly broken up grass lands, have been less affected, but in the 

 majority of cases little difference has been perceived. 



We are compelled to come to the conclusion that the disease has 

 appeared more or less upon every variety of soil, and in every situ- 

 ation, on heavy and light, on dry and wet land, on moss, clay, loam^ 

 gravel and sand, at every elevation where the potato is cultivated. 

 No variety of soil yet noticed, has proved an efficient protection. 



Query 8.- — In what varieties of potato has the disease appeared 

 most ? Have old, or long cultivated varieties failed more than new^^ 

 or recently introduced varieties 1 



The first part of this query has been answered differently from 

 almost every farm and neighborhood. In many places all are said to 

 be affected alike. 



Mr. Elliottj Hardgrovej Dumfriesshire^ says, "As a general rule 

 it may be remarked that it is worst upon the varieties which grow 

 w'eak stems, and not so bad upon those kinds which are stronger^ 

 and more vigorous in their stems." 



Mr. Girdwoody Corsforphine, Mid-Lothian: " I possess twenty 

 varieties, they are all equally bad." 



Mr. Maxwell, of Munches: "The old varieties are decidedly the 

 worst. The soundest potato is that called cups. 



Mr, Smith, Ladyland, Dumfriesshire : " Cups have been long culti- 

 vated, and have failed less than any others." 



Mr. Goodlet, Grant'' s Braes, Haddington: "Irish cups are not 

 much affected." 



Mr. Hird, Crossjlaf, ./lyrshire: The Irish cups, and early kinds 

 are less affected than any others." 



This would seem a clear verdict in favor of the cups, but the next 

 answer is of a different cast. 



Messrs. James and John Jackson, Houston, Renfrewshire, say, 

 " With us the Irish cup potato, is the worst diseased. But it is not
