The Spraying of Plants. 



Several French machines are built in this manner, one of the 

 advantages claimed being that the outfit is more durable, since 

 the materials applied do not come in contact with the working 

 parts of the pump. The Galloway type, however, is at present 



more popular. 



The use of Paris green to de- 

 stroy the plum curculio, canker- 

 worm, and the codlin-moth, soon 

 created a demand for pumps and 

 nozzles which would be effective 

 in applying sprays to well-grown 

 trees. Several firms soon began 

 to supply this demand. C. J. 

 Ilumsey & Co., of Seneca Falls, 

 X.Y., had been supplying various 

 garden engines as early as 1858, 

 or even before. In 1860 the firm 

 advertised a garden engine as 

 an instrument for " the throwing 

 of liquid compounds, 

 such as whale-oil, soap- 

 suds, tobacco - water, 

 etc., for destroying in- 

 sects on trees, roses, 

 and other plants." The 



K- f\\ outfit consisted of a 



M tank resting on two 



4E0J IKS^ wheels in front and on 



two legs behind ; it 

 was moved about as a 

 wheelbarrow is. The 

 pump had an enor- 

 mous air chamber, a 



part which has fortunately been reduced in size during later 

 years. Various small hand or bucket pumps were sold soon 

 after. 



On Xov. 6, 1860, Messrs. W. and B. Douglas, of Middletown, 

 Conn., obtained a patent on a garden or greenhouse engine, and 

 in the same year the same company patented its " Aquarius," a 

 bucket pump still advertised,

 form especially designed for spraying purposes.
