VARIETIES IN CULTIVATION. 21 



The varieties more generally approved of are 

 CLASS I. Agricultural Late Kidney. In length nearly 

 thrice its average diameter, slightly flattened and thick- 

 ened towards the point; eyes few and very shallow, or 

 almost level with the general surface; colour whitish; 

 quality superior. Two tubers were received by us 

 (Messrs. Lawson) from the late Mr. Loudon, the largest 

 of which measured 10 inches in length by 11 inches cir- 

 cumference at the middle, and weighed 2 Ibs. 6J oz. 



Bedfordshire Kidney. Stem rather erect, about 30 to 

 33 inches high ; tuber long, thick, and straight ; colour 

 reddish ; medium, good flavour, and very healthy. 



Blue Don. Stem stout and spreading, about 30 inches 

 in height ; tuber round and hollowed at stalk ; colour dark 

 bluish purple, with small whitish blotches; mealy and 

 very good flavour. Much liked, and largely cultivated in 

 some districts in Ireland. 



Common or Scotch Don. Stem strong and spreading, 

 about 30 inches high ; tuber round and hollowed at the 

 stalk ; colour white, and reddish purple about the eyes ; 

 mealy, good flavoured, and tolerably healthy. As a feed 

 potato this variety is more extensively cultivated in 

 Mid-Lothian and adjacent districts than any other. Wheo. 

 cooked its tubers are much whiter-fleshed than those of 

 the Perthshire Reds and some others of the more esteemed 

 field sorts; they are also mealy and of an agreeable 

 flavour, but when grown to a large size, often hollow, or 

 hard and waxy in the centre. 



Cork Red. Stem spreading, about 2 feet high ; tuber 

 flattened slightly, oblong and pointed; colour roughish 

 and reddish brown ; mealy, good flavoured, and healthy. 

 The favourite variety in some parts of Ireland. 



Douglas Irish Kidney. Stem spreading, about 2 feet 

 high ; tuber long, and thickest towards the point ; colour 

 darkish purple ; mealy, good flavoured, and healthy.
