    Two problems, winter hard red winter and/or hard red spring wheat; oats; rye, malt barley and corn will be used to make up the grading phase of the contest.
    No actual grain samples will be worked. Master sheets listing grading factors will be furnished to each contestant.

  3. Only the following special grades may be used in the contest:

    light smutty
    garlicky
    treated
    ergot
    OATS

    garlicky
    ergot
    bleached
    bright
    RYE
    ergoty

  4. Grading will be done on two problems from card factors only. Approximately five minutes will be allowed for each problem.
  5. The contestant must indicate with an "X" in the proper circle on the score sheet the correct grade, subclass, class and factors which apply for each problem. In addition, information will be furnished on the card whereby the contestant will be expected to determine percent dockage and special grade where applicable.
  6. Grading factors: A reason why a grain goes down in grade. A grain which grades No. 1 has no grading factors and need be given none. A grain grading No. 2 or lower must have a factor or factors which bring it down. Only the factors which bring it down to the lowest grade should be marked.
