When the potatoes are sound and in good condition most of the 
12.47 per cent waste in peeling is composed of flesh around the eyes. 
If the eyes are deep it is not possible to gouge them out with a knife 
as carefully as the skin is removed by the peeler. This loss is less 
important than an equally deep peeling elsewhere, however, for the 
internal medulla extends a branch to each eye, lessening the propor- 
tion of dry matter to water and reducing accordingly the food value 
of the flesh. East ® has shown that the quality of the potato varies
