With two or three exceptions, which are easily explained, there is 

 very little difference between the filtered and nnfilterd solutions after 

 standing for several Aveeks, neither do they vary much from the original 

 solutions. In the first sample, the filtered solution 10, was found to be 

 much weaker than the imflltered, and this is explained by the fact 

 that the stopper of the bottle containing the solution did not fit tightly, 

 thus allowing it to be more or less exposed to the air. Samples 3B 

 and 4B were found to contain loss soluble sulfur than the corresponding 

 filtered solutions, and this is explained by the fact that from each of the 

 barrels in which these solutions were stored portions were removed 

 for use b}^ the Horticultural department thus leaving a large air space 

 oi\'er the solutions. These results confirm .the conclusions of other ex- 

 I>eriments, viz : that if the lime-sulphur is to be stored for any length 

 of time the containers should be filled completely full and stoppered 

 tightly to exclude all air. 



We may conclude then, from the above exiieriment, that when the 

 lime-sulphur solutions are made according to the formula recommended 

 there is practically no deterioration in the solution when kept in con- 

 tact with the sediment providing it is stored properly. 



Later results have demonstrated that when the lime-sulphur solution
