DILUTIONS FOR DORMANT AND SUMMER SPRAYING WITH LIME-SULPHUR 



MIXTURES. 



" In making, slake the lime in about 10 gallons of hot water, 

 adding the lumps of lime gradually to avoid too violent boiling and 

 spilling over. . . . The sulfur must be thoroughly moistened 

 and made into an even, fluid paste without lumps (before adding to 

 the lime) .... Pour in the sulfur paste gradually during the 

 slaking, stirring constantly to prevent the formation of lumps, 

 and when the slaking has finished add the full amount of water 

 and boil gently for one hour. If kettles and fire are used, more 

 ' than the required amount of water may be used at first, to com- 

 pensate for evaporation, or the volume may be kept constant by 

 adding successive small quantities to hold the mixture at the 

 original level, as shown by a notch on a stick resting on the bot- 

 tom of the kettle, and marked when the mixture first begins to 

 boil. When boiling with live steam the mixture will be more 

 likely to increase in volume than to decrease, so that no water 

 need be added.
