may sometimes be found in sufficient numbers to 

 make handpicking advisable. 



Varieties have been introduced in large numbers, 

 but only a comparatively small list has ever suc- 

 ceeded in becoming popular in a commercial way. 

 The varieties may be classed as white and green. 

 The white group comprises all of the so-called self- 

 blanching sorts which have come into common use 

 only during comparatively recent years and have 

 done much to revolutionize celery culture. The 

 green sorts are of the larger growth and require 

 more careful work in the matter of blanching. 



A CELERY HILLER 



White Plume> Golden Self-Blanching, Giant Pascal, 

 Winter Queen and Boston Market are perhaps the 

 leading varieties under cultivation at the present 

 time. 



Celeriac is a plant belonging to the celery family, 

 but grown for its roots rather than leaf stems. It 

 is used for flavoring and also for cooking purposes. 

 It is not extensively grown in this country. It re- 

 quires the same soil and cultural conditions as the 

 celery and may be readily stored like all other 

 root crops.
