coneentriited lime-sulfur mixture. The smaller growers are 

 buying it unless it happens that they have an outfit or 

 equipment with which to prepare it at home. It is easy 

 enough to make and is mueh cheaper than the commercial 

 mixtures. We seldom buy any commercial lime-sulfur ex- 

 cept to use in an experimental way. 



MR. MUNROE :M0RSE: Can you make it and get it as 

 strong as the commercial? 



PROF. FARLEY: We have not been able to. The ma- 

 jority of our home-made lime-sulfur concentrate will test 1. 

 27, but provided you do not dilute that as much as the com- 

 mercial concentrate, you have the same mixture when 

 actually apjilied to the trees. We find even at that lower 

 strength it is cheaper under our conditions than it is to pay 

 the freight on "vvater for a certain distance. The competition 

 is so great now between commercial lime-sulfurs that you 

 can buy it at almost any price. 



MR. PARS0X8: Can the material that is cr^^stalized in 

 the barrel be used? 



PROF. FARLEY: We have used it by heating the lime- 

 eulfur enough to dissolve the crystal. 



:\IR. PARSONS: And get just the same strength? 



PROF. FARLEY : We always test our lime-sulfur with 

 a hydrometer before using, no matter whether it is com- 

 mercial or home-made, and then we dilute it accordingly. 



MR. PARSONS : Doesn 't that crystalization on the bar- 

 rel weaken the rest? 



PROF. FARLEY; It does to a certain extent, but you 

 can test it. 



:MR. PARSONS: Without a test you don't know what 

 it will do if you carry it over? 



PROF. FARLEY: I doubt if it weakens it very much, 

 provided you heat it enough to dissolve all the crystals. 



:\rR. WARE: Have you noticed any great variation in 

 tests with the hydrometer? 



PROF. FARLEY: Very little variation. 



SECRETARY BROWN: What is the test for diluting?
