400 ' Bulletin 149. 



During the past few years various substitutes for the arsenical 

 poisons have been on the market. In 1888, the Vermont Station pub- 

 lished the analysis of slug shot. 



Arsenic (AS2O3) 1.58 per cent. 



Copper oxide 60 per cent. 



A sample recently examined at this Station contained : 



Arsenic (AS2O3) 60 per cent. 



Copper 1. 15 per cent. 



The Massachusetts State Station in 1893 examined several insecti- 

 cides, and, among others, found the Oriental Fertilizer and Bug 

 Destroyer to contain 2.38 per cent, arsenic. 



During the present season, a number of inquiries have been received 

 at this Station concerning insecticides and fungicides. As it is too 

 soon to give results of actual trials, only the chemical composition of 

 the substances can be given, which the reader may compare with the 

 older insecticides and fungicides. 



LAUREL GREEN. 



A new preparation under the name of Laurel Green, is on the 

 market, and is offered for sale as a substitute for Paris green. It 

 also claims virtue as a fungicide. A chemical analysis shows it to 

 contain arsenic, copper and lime and sulphuric and carbonic acids. 

 These same substances would be found in a mixture of Paris green 

 and Bordeaux mixture after drying. The copper and arsenic were 

 determined. 



Copper (Cu) 10.00 per cent. 



Arsenic (AS2O3) . . . . , 7.75 per cent. 



BUG DEATH. 



While it may be possible to combine both insecticidal and fungicidal 

 properties in the same compound, there may be some doubt about the 

 economy of depending on such preparations to act as fertil^izers also. 

 Nevertheless, in the advertising matter accompanying a sample of 

 Bug Death, the following statement is made : 



" I will undertake to guarantee it, as not only is it a fungicide and 

 insecticide, but, as well, it acts as a fertilizer. It is sure death to all
