only on the threshold of the great returns which workable peat 

 deposits hold out to the industries combined with agricultural pro- 

 duction. Until field work and experiments in this country begin to 

 be conducted systematically on peat deposits, however, with a well- 

 understood profile structure, and provision made for complete and 

 continuous records, the methods and the results obtained in Ger- 

 many, Sweden, and Holland will remain the chief sources of informa- 

 tion and of practice. A critical and comparative study of the 

 structural features and field conditions of American peat deposits 

 is alone decisive. It is prerequisite in establishing the scientific 

 foundation and the best practices which are necessary to successful 

 utilization of peat-lands in this country.
