19. Harvesting and marketing. — Cabbages should seldom be 



harvested until the heads are solid and mature. The crop is 



usually cut with a 

 strong, sharp butcher 

 knife. If to be buried 

 or stored with most 

 of outside leaves re- 

 maining, a sharp 

 hatchet will be found 

 convenient, when a 

 stub of the stem four 

 or five inches long 

 should be left, which 

 will serve as a very 

 useful handle. 

 Most markets demand fairly close trimming. The crop is 



usually packed in baskets or crates for shipment and sold by 



count or by weight on local markets. 

 Yields vary from ten to twenty or more tons to the acre, and 



there is the widest range in prices.
