In most of these orchards public meetings were held showing 

 methods of pruning and of making proper insecticides and fungi- 

 cides, and also applying the same. The chief material used for the 

 dormant spray was lime-sulfur solution, either home-boiled or com- 

 mercial. In every orchard we made enough to show the methods of 

 preparation. These consist in using two pounds of sulfur for each 

 pound of fresh lime and for each gallon of water. The lime unslaked 

 is put into the kettle, and enough water is stirred with the sulfur to 

 make it pasty, and this is poured over the lime, and enough water is 

 added to slake it. The fire is started, and some more water is added 

 and the boiling continues. It is then boiled from one-half to three- 

 quarters of an hour and allowed to settle, or is strained and stored 

 for future use to be diluted with the hydrometer test to si^ecific gravity 

 test of 1.03, which is generally about one part of the concentrated 

 material thus prepared to seven parts of water. 



This formula is only for dormant spray. As a spray material, 

 when in leaf, we used on the pome fruits (apple, pear and quince) 

 one gallon and one quart of concentrated lime-sulfur solution in 

 forty-nine gallons of water, thus making a fungicide for spraying on 

 leaf and fruit, and to this was added one pound of dry arsenate of 

 lead, or two pounds of arsenate of lead paste, to act as an insecticide 

 for chewing insects, such as the Codling moth, Tent-caterpillar, Bud 

 moth. Grasshoppers, Canker worms, Webworm, Curculio and others. 

 This application was made just after the petals fell, and again in a 

 month.
