VARIETIES IN CULTIVATION. 23 



flattened ; colour red ; skin smooth ; mealy, good flavoured, 

 and healthy. There are three varieties in cultivation 

 the true, or " Oblong Flat," the " Small-eyed Round/' and 

 the " Large Deep-eyed/' These three are grown indis- 

 criminately, and are known in the markets under the 

 names of Common, Scotch, or Perthshire Reds, the latter 

 of which has been applied since they became so much 

 esteemed in the London markets. The Small-eyed is 

 about equal to the first-named in quality, but rather

 slightly curved; colour whitish, with a reddish point
