then are fit for use. The establishment at Concarneau, can man- 

 ufacture from four to five tons per day, in a perfectly dry state, 

 ■working only twelve hours per day. The perfect desiccation

They constitute the very essence of all manures, for cereal 

 crops especially. And great saving is made of cartage, and men

 The learned Professor Way is lecturing upon it.

Adrian Eergen, of Flatbush, Long Island — I have seen it lately

 they think that they shall lose by the disease four thousand 

 bushels of their crop. I do not hear of the rot elsewhere parti- 

 cularly. 



F. D. Tucker, of Bushwick, Long Island, presented a Christina

The members tasted, and unanimously agreed that it was very 

 delicious.
