the cork and leave the box in position for 

 three-quarters of an hour. I believe this 

 easier than spraying with an insecticide. 

 The odor soon departs, though while it lasts 

 it is terrific, and there is no trace of the 

 chemical left. Weevils in grain and other 

 seeds are killed in the same manner, a small 

 amount of carbon bisulphide being poured 

 over the seed, which is in a closed receptacle, 

 the insect being entirely destroyed, while the 

 seed is absolutely uninjured. Bulletin No. 

 145 of the United States Department of 

 Agriculture is a most interesting pamphlet 

 on this extremely vile-smelling but valuable 

 insecticide. It may be secured for the 

 asking. 



HOW TO MIX PARIS GREEN 



(The standard arsenical poison, a whole- 

 sale wav of killing insects that chew.) 



Paris green and London purple are the two 

 principal poisons used for chewing insects. 

 To make a spraying solution, mix one pound 

 of Paris green with 100 or more gallons of 

 water; one pound of milk of lime prevents 

 injury to leaves, and the latter should always 

 be used when making the London purple 

 solution, which is compounded in the same 

 proportion as Paris green. To use them dry 

 or in powder form, take one pound of either 

 poison and mix with fifty pounds of flour or 

 100 pounds of land plaster, fine road dust or 

 coal ashes. This can be dusted on the leaves 

 through a coarse muslin bag or through a 

 fine sieve. The London purple solution is 

 the cheaper of the two and adheres to the 

 foliage longer. Tobacco dust sprayed or 

 blown onto the leaves and stems is also a 

 remedy. 



HOW TO MAKE KEROSENE EMULSION 



(The standard remedy for plant lice and 

 some other sucking insects.) 



Kerosene emulsion is made by dissolving 

 half a pound of soap, and adding two gal- 

 lons kerosene while hot ; this must be churned 

 hard until the two ingredients are thoroughly 

 mixed, when it becomes a creamy paste. 

 This must be diluted with twenty to twenty- 

 five parts of water before it is sprayed on 

 the stems and foliage of a plant. You can 

 use one gallon of sour milk in place of the 

 half pound of soap, and dilute in the same 

 proportion before using. 



THE RESIN-LIME WASH 



The concentrated solution is made in this 

 way for use against the cabbage worm: Five 

 pounds of pulverized resin; one pound of 

 concentrated lye; one pint of fish oil; five 

 gallons of water. 



The oil, resin and one gallon of hot water 

 should be placed in a kettle and heated until 

 the resin is soft. Then add, very carefully, 

 the solution of concentrated lye (directions 

 for making this solution will be found on the 

 can). Next add the rest of the water (four 

 gallons), and boil until a few drops in some 

 cold water produce a clear, amber-colored 

 mixture. If there are not five gallons of the 

 mixture* when boiling is finished, add enough 

 water to make that amount. Take this con- 

 centrated stock or solution and to one gallon 



of it add sixteen gallons of water, three 

 gallons of milk of lime or whitewash, one- 

 fourth of a pound of Paris green. This 

 mixture should only be made as needed, as 

 after the lime and Paris green are added it 

 becomes cloudy and gummy, clogging the 

 sprayer. 



BORDEAUX MIXTURE, THE STANDARD 

 FUNGICIDE 



Copper sulphate is the most practical 

 destroyer of plant diseases known, but if 

 used alone it burns the foliage and therefore 

 it has to be mixed with lime, which also 

 makes it stick, so that a light rain does not 

 wash it away. This combination of copper 

 sulphate and lime is the Bordeaux mixture. 

 If you have a large enough place to justify 



a barrel pump you should make your own 

 Bordeaux mixture, but I don't bother with 

 it. I buy it ready mixed and dilute it to 

 various degrees for different kinds of plants. 

 The directions come. with the mixture. 



AN IMPROVEMENT ON THE "GOOD OLD WAY" 



Hand picking is the only thing for some of 

 the meanest "critters" of them all. You 

 may sniff and talk haughtily of "scientific 

 methods," but sooner or later your pride will 

 take a fall and you will humbly take your 

 stick and pail of kerosene and make the 

 rounds. Direct contact is unspeakable, and 

 quite unnecessary. Use the pail or fold 

 them gently but firmly in a near-by leaf. 



Resolved : That we beat the insects this 

 year and have the best vegetables ever known!

 throws a spray fifteen feet high and is therefore useful for spraying trees as well as bushes and vegetables
