Eight of the parties who purchased "Scalecide" directly received 

 the product which is now on the market, and in every case the re- 

 sponse indicates satisfaction with the product. One orchard ex- 

 amined by myself did not give so good a record, and this was where 

 the largest amount of the material had ])een used. It seems prob- 

 able that low temperature and the method of application were some- 

 what in fault here, because the K.-L. was completely ineffective, also, 

 and none of the applications were really satisfactory. 



On the whole, the record is not quite equal to that of "Kill-0- 

 Scale," which had, however, a much more thorough test under some- 

 what more favorable conditions, in that fall applications were made. 



The price of "Scalecide" is $1 per, single gallon, and in barrel lots 

 fifty cents, F. 0. B. at ISTew York. This brings the cost down to a 

 fiofure that makes it available for orchard work. 



Kerosene Limoid or K.-L. 



This combination is made by adding four pounds of limoid to one 

 gallon of kerosene and stirring thoroughly until a sloppy mass is 

 formed. If then a little free oil appears on the surface, add a little 

 more limoid and stir until it is completely taken up and no more oil 

 appears. Add water to equal the amount of kerosene, stirring con- 

 stantly and hard. Then, after this forms an even mixture, add water 

 sufficient to reduce to spraying strength, i. e., if a 30 per cent, mix- 

 ture is desired, four gallons of water should be added to every gallon 

 of kerosene used. Wlien all the water is added, stir violently by 

 pumping the mixture back into the spray tank until a smooth, even 

 emulsion is formed, that is quite stable and sprays readily through 

 the finest nozzle, provided no foreign material has been allowed to get 

 into the tank. 



Limoid is a finely-ground and very light, dry-slaked magnesium 

 lime : corson's lime, which is a similar product, has been used for the 

 same purpose ; and carefully slaked and sifted dry hydrate of lime does 

 almost equally well. The lime, in its very finely divided condition, 

 takes up the kerosene and forms a carrier, by means of which it is 

 evenly suspended in the water. To be equally effective in all its parts, 

 the diluted mixture must be very thoroughly emulsified, so that there 

 shall be no settling of heavier particles and no free oil. That makes 

 the necessity for the churning process by pumping back into the
