two parts ; this at the rate of 1^^ cwt. per acre, followed up by 

 a dressing of 2 cwt. per acre of sulphate of ammonia. 



The following note of experiment in treatment of Clover- 

 sickness showed entirely satisfactory results : — " A mixture 

 of sulphate of potash 3 cwt., and sulphate of ammonia 1 cwt. 

 per acre, was applied on April 3rd." The disease ceased, and 

 the Clover made a very vigorous growth, which was continued 

 markedly in the second crop. Sulphate of iron at the rate of 

 2 cwt. also answered very well both for stopping the disease 

 and giving good growth ; at the rate of 1 cwt. the sulphate of 

 iron was not so serviceable. 



The above, it will be noticed, are not recipes for prevention 

 of Aphelencld in Strawberry plants, but of Tylenchi in Oats 

 and Clover, but there is so much in common in the nature of 

 the two attacks that experiment might very likely give good 

 results.

The following observations refer to the attacks of a small

 named by two referees, I give both appellations.
