but may be destroyed by one of the many prepared 

 insecticides now in the market, which are usually in 

 a convenient form for use, and are efficacious if applied 

 according to the maker's directions. A good preparation 

 is made from one pound of soft soap and one pound of 

 Quassia chips boiled in three gallons of water for about 

 three or four hours, strained, mixed with other three 

 gallons of water, and applied warm. 



Under glass, fumigation, is usually the most suitable 

 way of dealing with Aphides, and the old remedy of 

 tobacco-paper is becoming superseded by XL ALL or

Red spider is often troublesome, especially under 

 glass, and may be dealt with by Gishurst Compound or 

 one of the numerous preparations for the purpose, as 

 well as by dusting flowers of sulphur on the leaves, or 

 using such a solution as one pound of flowers of sulphur to 

 two pounds of quicklime, boiled in four gallons of water. 



Fumigation with some insecticide is also efficacious 

 under glass ; while walls on which pests have gained a 

 hold may be cleansed by mixing one pound of flowers of 

 sulphur and two ounces of soft soap with clay and soot 

 mixed with water to the consistency of paint. 



Mildew is also very troublesome, and Bordeaux 

 Mixture is one of the best remedies for plants outside. 

 It is poisonous, and a wise precaution is to refrain from 

 applying it to fruits within some weeks of their being 

 gathered. A good recipe for its preparation is I lb. 

 quicklime, dissolved in cold water, with I lb. sulphate 

 of copper, dissolved in a little hot water, added together 

 when cool to 10 gallons of water, and applied with a 

 spray, stirring thoroughly. Some add I lb. of treacle to 

 the lime, as it slacks, to enable it to adhere more firmly. 



Scale and mealy bug are bad pests under glass, and 

 may be destroyed by such things as Kerosene Emulsion,
