120 COOL SEASON VEGETABLES 



12. Forcing asparagus and rhubarb is a good winter exercise or project. 

 Dig the largest roots and let them freeze. Later take them into a hotbed or to 

 a cellar window and wet them with water slightly warmed. Do not force the 

 growth too rapidly. Record the cost of labor and the value of products secured. 



13. Vegetable Survey. — Make a list of the common cool-season vegetables 

 of your region, and let each member of the class report on them for his own 

 neighborhood — quantities or areas planted, purposes for which they are grown, 

 varieties, why others of the list are not grown, etc. 



14. Market Prices.— Let the class visit a good vegetable market if possible, 

 or let one student do this and report on the manner of preparing each vege- 

 table for market, containers, prices, and quantities handled. 



15. Garden Returns. — From such facts as those obtained in 13 and 14, 

 calculate the garden returns of some good gardens, if products were sold in 

 market.
