HOMEMADE LIME-SULPHUR CONCENTRATES. 
The question of the preparation at home of concentrated lime- 
sulphur solutions which will not crystallize upon cooling, thus dupli- 
cating the commercial product, has been investigated by the Bureau 
of Entomology, as well as by numerous experiment station entomolo- 
gists, notably by Profs. Stewart, Cordley, Parrott, and others. It 
has been demonstrated that it is practicable for orchardists to pre- 
pare concentrated stock solutions of lime-sulphur wash for immediate 
or later use, and many orchardists employ this plan. The necessary 
details for the preparation at home of lime-sulphur concentrates are 
given. in Farmers’ Bulletin 650 of this department. Those interested 
in the preparation for storage of lime-sulphur concentrate should 
write for this publication.
