These meadows receive an annual supply of fresh ooze from 

 waters of the Vosges, so that the soil does not require an arti- 

 ficial supply of manure. The hay, being consumed by his 

 cattle, their manure goes to supply the uplands, so that the 

 saline matters used on his ploughed land really come from the 

 alluvium deposited annually on his meadows by the overflowing 

 water. 



Suppose that there had been no restoration of these matters 

 to the soil of his meadow, and that he had sold his hay, it 

 is obvious that there would have been a large removal of val- 

 uable salts from the soil, and his land would, in the course of 

 time, become exhausted or impoverished, so as to be unpro- 

 ductive. 



Mr. Owen Mason, of Providence, Rhode Island, has esti- 

 mated the amount and proportions of inorganic matters re- 

 moved from the soil of Mr. Adam Anthony's farm, in North 

 Providence, in the course of eight years, as follows. The crops 

 raised were alternate growths of millet and clover.
