sulphur in solution in their preparations. Analyses of the 
Samples of the different brands sold in this State during the 
past year show that this variation may still occur, for the 
range in densities of the solutions that were examined was 
from 26.80° to 33.90° Beaumé. The approximate amount and 
value of sulphur in solution in preparations included in this 
range of densities are given in the accompanying table.

OCCURRENCE OF SEDIMENT. 
In making a lime-sulphur wash, there is always more or less 
sediment or residue, which on settling largely accumulates in 
layers on the bottom of the cooking vessel. This is composed 
for the most part of undissolved lime and sulphur, of insoluble 
compounds derived from the lime and sulphur and of various 
impurities of the lime, principally magnesium. One of the 
striking differences among the brands sold in this State during 
the past year was in the relative freedom from sediment or 
sludge. Some preparations were entirely clear, the residue 
having been excluded, while preparations of another brand were 
apparently neither strained or filtered, and contained a vary- 
ing amount of sediment. The variation of the different brands 
in this respect is shown in the accompanying table. 
* Valuation is based on solution testing 33° B. and selling for $10.00 a
