Repeated experiments have proved that Barilla is 

 the most powerful manure that can be applied to land ; 

 it produces to the farmer and gardener a considerable

 and rank haulm and leaves, instead of well-flavoured 

 fruit and sweet vegetables, may be restored to fertility 

 by a moderate dressing with Barilla, trenched into the 

 ground at the rate of five hundred weight per acre.

 Barilla left in them after the manufacture of the soap ; 

 and it appears by analysis, that one ton of soap ashes 

 contains only from seven to ten pounds of Barilla. 



With any sort of crop on a farm, this article may be
