Horticultural department iii making their lime-sulphur sprays for their 

 orchard work. So it was made up under normal conditions. The so- 

 lutions were made up according to two formulas — one was (10 lbs. of 

 lime to 12.5 lbs. of sulphur and 50 gallons of water. That is the one 

 designated A in the table. The one designated )^ was made up accord- 

 ing to the formula 50 lbs. of lime, 100 lbs. sulphur and 50 gallons of 

 \\ater. 



Table II. 



If you examine the figures here in this table you will find that the 

 amount of suljihur which has gone into solution depends on the amount 

 of the calcium oxide in the lime used; that is, the lime containing the 

 largest amount of calcium oxide gave us the largest amount of sulphur 

 in solution. We have only given the results for total sulphur in solu- 

 tion and sulphur in sulphide form. Now the sulphide sulphur is the 

 amount of sulphur which is chemically combined with the lime and is 

 known as calcium sulphide. The lime also combines with the sulphur, 

 to form calcium Ihio-sulphate and calcium-sulphate. But the amount 

 which goes into solution in these forms is comparatively small so that 

 the largest amount of the lime and sulphur are combined as calcium 

 sulphide. If we examine the results in table No. II in connection with 

 the figures given in table No. I we will find that the sample made from 

 the lime containing the greatest amount of calcium oxide, has the larg- 

 est amount of sulphur in solution. For instance the lime sample No. 

 5 containing 57.66% of calcium oxide gave 13.68% of sulphur in solu-
