Bnles for Determining Kumlier of Dilu- 

 tions and Density of Spray 



If the density of the commercial solu- 

 tion or the home-made wash has been 

 first determined by the use of a hy- 

 drometer, sprays of any desired density 

 may be calculated by using the above 

 table. Hydrometers do not detect im- 

 purities in lime-sulphur solutions; these 

 can be determined only by chemical an- 

 alysis. The rule for obtaining the num- 

 ber of dilutions is as follows: Divide 

 the decimal of the concentrate by the 

 decimal of the spray desired, the quo- 

 tient will be the number of dilutions. 



Example: The concentrated lime-sul- 

 phur solution tests 34 degrees Beaume, 

 which by the table is 1.288 specific grav- 

 ity. It is desired to use the lime-sulphur 

 solution to spray upon trees at 3 degrees 

 Beaume, which is 1,020 specific gravity. 

 The decimal of the concentrate is ,2SS, 

 which, divided by .020, equals 14.4, which 

 is the number of dilutions required, and 

 which, of course, is obtained by adding 

 13.4 volumes of water to one volume of 

 the concentrated lime-sulphur solution. 

 This rule is based upon the general fact 

 that the density of a solution heavier 

 than water varies inversely with the
