CALIFORNIA SCALE SPRAY. 



Water 98.88% 



Solids 1.11% 



The solids having the following composition : 



Soap 70.77% 



Sodium carbonate 8.08% 



S. .ilium fluoride' 13.23% 



Small quantities of silica, calcium, iron and aluminum salts. 



From the analysis this material appears to be practically a spray com- 

 posed of : 



Dry soap 8.5 pounds 



Sodium fluoride 1.25 pounds 



Water 100 gallons 



Comment on the solution, on account of the large volume of water 

 composing it, is scarcely necessary. 



SHURE-KIL. 



A milky looking fluid with a slight reddish tinge, having an odor of 

 distillate. It has the peculiar property of not wetting glass or tin. 

 After standing a few hours a slight separation of oily drops is noticed 

 on the surface. The emulsion is not broken by copious dilution with 

 water, but is broken by the addition of a strong acid, strong alkali, or 

 brine. The material contains approximately 50 per cent of total oils. 

 The emulsifier appeared to be a sulfonated oil. 3 Examination of the oil 

 separated from the emulsion gave the following results : 



Specific gravity at 17° C .878 



Equivalent to 29° Be. at 60° F. 



Flash test 128° F. 



Sulfonatable oils 3 50% 



TRIUMPH. 

 A dark brown clear liquid. With water forms a very good milk-white 

 emulsion. Has strong odor of cresol. 



Examination of the separated oil gave the following results: 



Total oils 76.00% 



Total phenols 5.25% 



Sulfonatable oils 33 '|?, % 



Specific gravity of separated oils at 60° F .SSI 



Equivalent to 28.9° Be. at 60° F. 



The material appears to be a "miseible oil" made from a distillate of 

 about 30° Be. gravity, and a cresol soap. 



PYROX. 



A light blue homogeneous paste containing moisture, 6.47 per cent. 

 Analysis of the air-dried powder gave the following results: 



Total lead (calculated as PbO) 43.15% 



Total copper (calculated as CuO) 7.10% 



Total arsenic (calculated as As~O s 2 0.50% 



Water soluble arsenic (calculated as AS2O3) .20% 



It appeared to be composed of acid, lead arsenate and Bordeaux 

 .Mixture. 



2 The laboratory has received many reports of severe foliage and fruit injury resulting 

 from the use of sodium fluoride as a spray, and on the other hand, there are cases in 

 which no iniurv has been noted following its use. 



a A sulfonatable oil is the term applied to an oil which is soluble in fuming sulfuric 

 acid. Experiments have shown that oils of this nature are much more injurious to 

 foliage than those which are not soluble in the acid. 



A sulfonated oil is an oil similar to the above, but which is already combined with 

 the acid and has great emulsifying properties, but is believed to be very Injurious 

 to foliage.
