[Jan., 



Tlie left hand lot in the present instance received calcium 

 sulphate, in addition to the same chemical manures which were 

 used in all of the other cases. The lot at the right was grown 

 with the aid of calcium chloride. In the former case but 4.3 

 per cent, of the tubers were scabbed and in the latter case none 

 of them were affected. 





.*^^:- 





This view shows the results with carbonate of lime at the 

 left, and with calcium oxalate at the right. In the former case 

 97.5 per cent, of the tubers were badly scabbed and in the lat- 

 ter case all of them were totally unfit for market, on ac- 

 count of scab.
