Application of Tobacco Water for destroying Insects. 533 



strong it may be, but, on the contrary, it seems to promote 

 their general health. Trees entirely free from insects have 

 been washed with it, and have given satisfactory proof of 

 this fact. 



The Tobacco liquor I have used, is procured from the 

 Tobacco manufacturers. In the process of preparing To- 

 bacco for use, the dried herb is steeped for a certain period, 

 and the water which it has absorbed, is afterwards expressed 

 from it, into the water in which it had been steeped. This 

 liquor is to be purchased at eight-pence or ten-pence per 

 gallon from the manufacturers, and should be obtained as 

 pure as possible without adulteration. 



One gallon of the liquor is stronger than any that could be 

 made from steeping several pounds of prepared Tobacco, in 

 the same quantity of water. The mixture of the Tobacco 

 liquor with water is in the following proportions, and 

 should be applied to the trees by means of a garden 

 engine, or syringe, taking care, in its application, that it is 

 given so forcibly that the under side of the foliage is well 

 sprinkled. 



For the destruction of the Green Fly, I mix one gallon of 

 Tobacco liquor to five gallons of pure water ; this quantity is 

 sufficient to wash three trees, twelve feet high, and each ex- 

 tending fifteen feet in breadth. For destroying the Black 

 Insect, one gallon of liquor to three of water. For destroying 

 the Caterpillars on Pear, Apple, Plum, and Apricot trees, and 

 on Gooseberry bushes, one gallon of liquor to four of water. 

 The above proportions have been frequently tried, and have 

 never failed of success.
