when grown and harvested under good conditions, its skin is a golden russet 

 color. 



The vines of the Late Petoskey are medium-large, with the main stem 

 upright and long-jointed. The lateral branches are decumbent. The stems 

 are streaked with dark purple. The leaves are rather small, dark green and 

 quite rough. The flowers are violet-purple. 



The tubers are round-flattened to oblong-flattened. Eyes are very shallow. 

 The skin is a deep russet and much netted. The sprouts are purple.

The White Rurals include such varieties as the Rural New Yorker No. 2, 

 Sir Walter Raleigh, and Carman No. 3. These three varieties bear a very 

 close resemblance to each other in vine and tuber characteristics. 



White Rurals have practically the same growing qualities as the Late 

 Petoskey (Russet Rural). Tubers of the White Rurals, however, have white 

 skins. 



The Green Mountain variety is grown quite generally in the Upper Penin- 

 sula of Michigan, where the growing season is usually cool and moist. This 

 variety is not adapted to sections where long periods of drought are of com- 

 mon occurrence. It matures about two weeks earlier than the Rural type of 

 potatoes. The cooking qualities are very good. The vines are large and 

 quite spreading by the end of the season. The stems are green and do not 

 bear any purple markings. The flowers are white. The tubers are oblong- 

 flattened or roundish-flattened; the ends are usually blunt. The skin is of a 

 dull creamy-white color and is more or less netted. The sprouts are white.
