The following is recommended in California for same purpose, 

 but for use on the peach: 



No. 2. Potash 14 Ibs. 



Caustic soda (98 percent.) .... 8 Ibs. 



Unslacked lime 5 Ibs. 



Fish oil, polar or seal 10 gals. 



Water to make 50 gals. 



Prepare as follows: First, dissolve the v soda and potash in ten 

 gallons of water, as with the preceding formula. Then slack the 

 lime with two gallons of water in the 50-gallon barrel to be used, 

 add the fish oil and stir well until the lime and oil form a thick 

 batter. Now pour the soda and potash solution, boiling hot, into 

 the barrel containing the batter, and stir well with a dasher for five 

 minutes. Leave standing from 4 to 6 hours; after this length of 

 time the barrel may be filled up with cold water, about two buckets 

 full at a time, stirring well to prevent lumps. Use the following 

 day and apply cold, in strength of one pound to a gallon of 

 water. 



In dissolving this soap for use do not boil, but weigh amount 

 to be used, place in barrel and pour hot water thereon, in propor- 

 tion of one pailful to every one hundred pounds of material ; then 

 stir briskly with a dasher until entirely dissolved. It can now be 

 reduced with cold water as above directed, making as many gallons 

 of wash as there were pounds of soap dissolved. After being well 

 stirred, it is ready for use. This wash is also recommended in Cali- 

 fornia for leery a on citrus trees and evergreens, and for Lccanhunx 

 on deciduous or other trees. 



Another summer resin wash, recommended by Professor Riley 

 for the red scale on the orange in California, differs from the above 

 washes by containing no potash, and proportionally more than 

 twice as much resin. It will doubtless be efficient for all species of 

 Aspidioius, except the San Jose scale, but if used on deciduous 

 trees it should be experimented with first to determine effect 011 

 the foliage. If the foliage is injured, more water can be added. 

 The formula is as follows:
