 ashes and plaster, equal parts, the joung plants to be 

 thoroughly covered with the mixture. Air slaked shell 

 lime (calcined oyster-shells) is much used by market gar- 

 deners in the same manner, it is also useful as a fertil- 

 izer. Fortunately the most destructive Saw Fly and 

 other enemies of this crop have not yet made their way 

 to this country, but as in the exceptional season of 1881- 

 83, large quantities of turnips were imported, it is not at 

 all unlikely that some of the British insects may have 

 come with them. 



In the Southern States, the Harlequin Cabbage-bug 

 (see p. 37) is very destructive to the Turnips.
