HOME BOILED CONCENTRATED LIME-SULPHUR. 



In making this solution a large kettle or iron cooker of some 

 sort is necessary. A stock feed cooker of large capacity will 

 answer. Cookers well adapted for this work can be obtained 

 of the Farmers' Supply Co., Philadelphia, Pa.; Montgomery, 

 Ward & Co., Chicago, Illinois, or the Wagner Mfg. Co., Sydney, 

 Ohio. 



We give here the formula of Prof. A. B. Cordley of Oregon 

 as the one best to recommend in view of our present knowledge 

 of the subject. 



Sulphur 1 10 lbs. 



Lime, best grade 55 lbs. 



Water sufificient to make 60 gallons. 



Slake the lime, mix the sulphur into a thin paste with a little 

 water, add it to the lime, add sufficient water to make 60 gal- 

 lons, bring to a boil and boil vigorously for 30 to 45 minutes. 

 The sediment is then allowed to settle, after which the clear 

 dark amber-colored liquid is drawn off and may be stored in 

 casks for future use." 



DILUTING CONCENTRATED SOLUTIONS FOR USE. 



With our present knowledge, the strength of lime-sulphur 

 to use — that is, the amount of water to add to a gallon of 

 the concentrated solution — depends upon the density or spe- 

 cific gravity. This may be determined by a cheap and simple 

 instrument called the hydrometer. This consists of a hollow 

 glass tube, its lower end terminating in a weighted bulb. Placing 

 this in a liquid, it sinks until the liquid displaced equals its 

 own weight. In light solutions, therefore, it will sink deeper 

 than in heavy or dense ones. The graduations to be read are 

 marked on the scale on the neck of the instrument, and are 

 in degrees Beaunie or in terms of specific gravity. In some 

 hydrometers both scales are given, but the Beaume is the one 

 most generally used. These instruments, costing from $1.25 to 

 $1.50, may be had of Bausch & Lomb, Rochester, New York; 

 Eimer & Amend, New York, N. Y., or any dealers in scientific 

 apparatus. They are absolutely necessary for the proper use 

 of lime-sulphur solutions, as not only may the product of one
