ux^on variety. It may be thick or thin, tough or brittle. A thick, 

 fairly tough skin is preferred. 



8. Flesh: T^Tien cut, firm, clear in color, free from hollow center, 

 dark rings, discoloration, woodiness. 



9. Freedom from blemishes: No scab spots or skin ruptures from 

 any other diseases, no cuts, bruises, scratches, or other defects. 



Practical exercises. — Students should practice on identifying the 

 different varieties of potatoes until they can be recognized at sight. 

 The chief characteristics noted above should be studied and students 

 taught to observe varieties from type. Use score card suggested be- 

 low or ask the State agricultural college for enough to supply the 

 class. Require the students to mark the points on the card. Com- 

 pare with a typical potato (either a real potato or a good picture of 

 one) to note any difference. Hold judging contests in which the 

 students will be required to judge and score the different varieties. 

 Ask for the help of the county agent in these contests. Make this 

 work of a practical nature, and drill until the pupils are able to 

 recognize readily the different kinds of potatoes and to score them 

 fairly accurately. The following form of score card may be used:

NoTE. — Give directions for using the above card. 



Correlations. — Language: Oral or written reports on the kinds 

 of potatoes grown in the district or in the State; how to judge po- 

 tatoes; a history of the chief classes of potatoes will all provide 

 abundant language work. 



History : Write a history of the potato, an account of its introduc- 

 tion into Europe, the story of Luther Burbank and the Burbank 

 potato. 



Arithmetic: If potatoes scoring 100 points are worth $2.50 per 

 bushel, what would be the value per bushel of the potatoes scored,
