ADDENDUM 
FoLLowine are the recent formulas and advice for lime-sulfur prepa- 
rations, comprising the concentrated and the self-boiled (continued, in 
this edition, from p. 195). These formulas are likely to be modified 
somewhat by further studies. See Manual Fruit Insects, pp. 482-3. 
The home-made lime-sulfur is prepared as follows (J. P. Stewart’s 
formula) : 50 lb. best stone lime (90-95% calcium oxide); 100 Ib. sul- 
fur (powdered commercial, 993% pure); water to make 50 to 55 gal. 
total product at finish. Put 10 gal. of water in kettle and start fire. 
Place lime in kettle. After slaking is well started, add the dry sulfur 
and mix thoroughly, adding water enough to maintain a thin paste, 
which requires about 5 gallons. After slaking and mixing are com- 
pleted, add water to make about 50 gallons, bring to a boil, and stir 
until the sulfury scum practically disappears; then add water to make 
about 60 gallons and boil down to 50 or 55 gallons. The material
