we may have half as much calcium oxide as of sulfur. The magnesium 

 oxide is harmful however, because of the fact that it separates out in 

 the form of a slime. From the above results it would seem best not to 

 stick to any one formula in making up the lime sulfur solutions, but to 

 obtain from the lime company, an approximate analysis of the lime to 

 be used, and take an amount such that the calcium oxide and sulfur mav 

 be in the ratio of one to two. 



EFFECT OF STORING THE SOLUTION IN CONTACT WITH THE SEDIMENT. 



To determine the effect of allo^ving a lime-sulphur solution to stand in 

 contact with its sediment, a number of samples of lime-sulfur were 

 made up, analyzed, and allowed to stand for periods varying from four 

 to seven weeks and again analyzed.
