and after the first true leaves appear, weed and thin 

 to three inches apart, being careful to distinguish 

 the seedlings from grass. 



3. Give frequent tillage and keep the plants free from 



weeds throughout the season. 



4. Some of the roots may be dug in autumn and others

 being covered with leaves or litter to prevent 

 alternate freezing and thawing at the surface of the 

 ground.

THE STORY. 



Write the story of how you grew a crop of salsify. When 

 does it blossom ? Is it an annual or biennial ? Do 

 you see any relation in root or plant to the common 

 chicory found along the roadside? Why is salsify 

 called "vegetable oyster"? What have you found 

 to be the best ways to cook the roots ?
