 better in the field, and I recommend the 

 application of this principle to the whole

 damaged plants. There are multitudes 

 of crops of celery that never pay for the 

 expense of their production. Some allow 

 their plants to stand too thickly, and 

 thus get them all tops and no bottoms. 

 Others, from keeping their beds too 

 damp, lose their crops from mildew ; and 

 each of a host of others suffers his espe- 

 cial penalty for the violation of some law 

 of vegetable growth.
