each of the two cells. 
28. Wild Carrot. — This eastern weed 
_| is not yet very common in the north- 
western states, but, when met, is easily 
recognized by its resemblance to the 
garden carrot — especially by persons 
who have seen the latter growing the 
second summer of its life history. The 
compact, flat-topped umbels of white 
flowers are very distinctive. This is the 
original of the cultivated carrot, but in 
its wild state it is reputed to be poison- 
ous. It occurs in meadows, 
pastures, and waste places. 
our garden parsnips and has the same appearance. 
It has a long tap root; the flowers are yellow; 
seeds broad and flat. It is said to be poisonous. 
30. Corn Cockle. — This plant, most com- 
monly found in wheat fields, attains a height of 
one or two feet, has but few branches, and those 
grow straight upward. It is quite hairy all over. 
The five calyx lobes are very narrow, and longer 
than the five purple-red petals. The pod ap- 
pears swollen and contains many round, black | 
seeds, which are poisonous. Flour made from 
grain containing much cockle is injurious to

health; and therefore such grain is reduced in grade by 
elevator and mill men.
