112 CALIFORNIA VEGETABLES. 



When both are cool, mix them together and add five 

 ounces of washing ammonia. When the mixture is clear, 

 after standing long enough to accomplish that, add cold 

 water to make five gallons. 



Some fungi are quite readily checked by the use of 

 dry sulphur, but when this is not effective, the copper 

 compounds will be found satisfactory. 



In many cases the attacks of fungi may be avoided by 

 keeping the plants growing thriftily, or by choosing vari- 

 eties which are not affected by the diseases to which other 

 varieties succumb. Wherever this course is open to the 

 gardener, it will be found more satisfactory than the ap- 

 plication of remedies. 



DESTRUCTIVE ANIMALS AND BIEDS. 



Against the larger marauders from the forest, the field, 

 or the barnyard, the farm garden must be protected by 

 an adequate fence close enough to exclude fowls and jack- 

 rabbits. For the latter purpose, closely set strands of 

 barbed wire are the cheapest material. The bottom wire 

 must be set low enough to prevent entrance by scratch- 

 ing under. Even when a neater fence is made of wire 

 netting, strands of barbed wire above and below are 

 often very useful. 



Squirrels. Ground squirrels should be destroyed in the 

 adjoining fields as well as in the garden, or its protection 

 is almost a hopeless undertaking. When the ground is 

 wet, squirrels are very satisfactoirly destroyed with car- 

 bon bisulphide, and this material, with appliances and 

 instructions for its use, can be had in nearly all the coun- 

 try stores. 



In dry soil the carbon bisulphide is not so effective, 

 and some of the many good squirrel poisons must be 

 used. The following has been shown to be very satisfac- 

 tory: 



Strychnine, one ounce; cyanide of potassium, one and 

 one-half ounces; eggs, one dozen; honey, one pint; vine- 

 gar, one and one-half pints; wheat or barley, thirty
