And which got the following applications : —

 3 cwt. bone-dust, and fully 3 cwt. hen and pigeon manure, night soil, and 

 household ashes— the bone-dust, and what follows, noted above, having 

 been mixed for several weeks previously to use, were repeatedly turned, 

 fermented, and reduced, then mixed with the Peruvian, &c. before sow- 

 ing—cost £3, 18s. per acre Scotch. 



Experiments made in Ayrshire. 



The experiments made in Ayrshire have only been success- 

 ful in the hands of Mr. Young, Highfield, those made by Mr. 

 Drennan, Holmston, and Mr. Cunningham, Shields, having 

 proved failures almost from the first. Owing to the unfavour- 

 able weather the crop in both cases was so much injured by the 

 fly that it was obvious from an early period that no reliance 

 could be placed on them, and it was considered mere waste of 

 labour to attempt to weigh them.
