LAST year's garden may have been a 

 pastime for odd hours, but this year's 

 gardeners have stepped into the front rank 

 of national defense. There is no gardener 

 so inexperienced that he cannot get val- 

 uable help from 



Corbelt's Garden Farming 



and no gardener is so old in his trade that 

 he will not continually have occasion to con- 

 sult it for assistance. 



A thorough-going systematic summing up 

 of important garden facts, simply written, 

 yet taking nothing for granted.
