could produce all the cabbage, onions, celery and mint needed by 

 the whole United States.^ In the eight North Central States* 

 alone there are 15,000,000 acres of marsh and swamp lands most 

 of which are capable of being drained and utilized for agricultural 

 purposes. It is plain, therefore, that all marsh and swamp lands 

 cannot possibly be utilized for trucking and gardening, but may be 



suitably used in growing general farm crops (Fig. 203).

 grown to subdue the sod. On pastured marshes, particularly, corn 

 is frequently grown as the first crop. Crops for marsh lands are 

 mentioned in the table on next page, together with the advan-
