REFERENCE KEY 



Reference books. — In all references used in this book, letters 

 are employed instead of the titles of the books. The letter W al- 

 ways means this particular book, Vegetable Growing. Projects, and 

 the numerals used with W refer to the page number. For example, 

 W : 14 refers to this book, page 14 ; W-VG : 10 refers to Vegetable 

 Gardening by Watts, page 10 ; L : 25 to Productive Vegetable Gar- 

 dening by Lloyd, page 25 ; and C : 50 to Garden Farming by Corbett, 

 page 50, etc. Many other books might be included, but the list 

 is sufficiently complete to meet the needs of most pupils. In fact, 

 if funds are very much limited, the last three volumes named above, 

 or any one of them, with the first, will serve the purpose. SH refers 

 to Stevens and Hall's Diseases of Economic Plants, Revised Edi- 

 tion, 1921.
