PLOWEES OF TUB FIELD. 73 



blooms early in the spring, and, as Hooker remarks, is 

 " too frequent " in the corn-fields. Its provincial name 

 varies in different localities kerlock,kadlock,andchaJ- 

 lock. It is a species of mustard, and the young leaves 

 are frequently gathered and used as greens by villagers. 

 It is somewhat difficult to distinguish this plant from 

 the turnip, or the Black Mustard (Sinapis nigra), 

 which is largely cultivated in Durham for its seeds, 

 which, when ground, form the mustard of commerce. 

 The flowers of all these are of a pale sulphur colour, 

 and are cross-shaped. 



In the early spring, on dry sandy soils, we find the 

 Long Scorpion Grass (Myosotis collina), though it 

 properly belongs to the dry walls. It has very bright 

 blue blossoms, which have entirely disappeared by mid- 

 summer, when its place is taken by the Field Mouse- 

 ear or Scorpion Grass (Myosotis arvensis), the true 

 inhabitant of our cultivated fields. This plant is 

 nearly allied to the forget-me-not, and is frequently 

 mistaken for it; but its little cluster of light blue 

 flowers have not the golden centre of the flower of 

 remembrance. When the days lengthen the fields 

 become the poor man's garden, and furnish forth the 

 most brilliant of our wild flowers.
