BOWKER'S 



Arsenate of Lead 



(DISPARENE) 



The Original and Best Brand 



N this brand, we offer an article of standard 

 strength and purity that mixes easily and 

 smoothly in cold water, remains in sus- 

 pension with normal agitation in the 

 spraying tank, and does not clog the nozzles. In 

 other words, a scientifically prepared mixture of 

 practical value to the practical man; — and that 

 does not burn. Prof. Slinglerland, of New York, 

 says: ** There has been some injury to foliage 

 resuking from the use of arsenate of lead, but so 

 far as I know your Disparene brand seems to 

 have caused no injury/^ 



^^PvrOX^^ is a smooth, creamy, carefully 



prepared combination of arsenate 



of lead (Disparene) and Bordeaux mixture. It 

 is giving grand results in the field as a double 

 header in destroying insects and checking blights 

 and rusts.
