 ammonium sulphate. Third year, clover, 880 Ibs. of incomplete 

 manure, No. 6. Fourth year, wheat, 17') Ib-;. of ammonium sul-

It will be seen from the above that Yille has two standard 

 elements in all his manures, that of superphosphate and sulphate 

 lime, and that they vary only in the nitrate of potash, chloiuK 

 potash, nitrite of soda and sulphate of ammonia. Tins is narrow- 

 ing the manure* elements, or sources of manure, down to an 

 unnecessary limit to the exclusion of other valuable 1 manures. It 

 was seen from Drs. Liechti and Vogt's experiments that as good 

 results were obtained from basic slag as that from superphosphates.
