EXPERIMENTS WITH FLAX OX BREAKING. 
23 
utilized in breeding experiments, strains may be produced which are 
better adapted for the various regions where flax is grown in this 
country. 
The question often arises whether Indian, Argentine, or Manchu- 
rian seed would be of value for seeding purposes in the United States. 
In order to throw some light on this subject, a representative assort- 
ment of varieties from India, Argentina, Manchuria, and other coun- 
tries has been selected from the nursery experiments, and such data 
regarding them as are available are presented in Table XI in compar- 
ison with similar data obtained on numerous northern-grown varie- 
ties and selections. In some instances only one variety of a type was 
available.
