Carbolic acid may be emulsified by boiling i pound of soap, shaved 

 fine, in i gallon of water, adding crude acid i pint, and then churn- 

 ing as for a kerosene emulsion. Diluted with 30 parts of water, this 

 mixture is effective as against root maggots attacking cabbage, 

 onions, &c. 



Turpentine has been used as a repellant with tolerably good effect, 

 and one pint in a bushel of lime will make the latter effective in 

 keeping the striped beetle from the base of melon and other vines. 



Resin, and the lime, salt and sulphur washes are much used in the 

 Pacific States and are very effective. In New Jersey the amount of 

 moisture almost continuously present in the air and the frequent rains 

 make them practically useless ; but for information the formulas and 

 method of preparation may be given. 



Summer Resin Wash. 



Resin 20 pounds. 



Caustic soda (70 per cent.) 5 pounds. 



Fish oil, 3 pints. 



Water sufficient to make, 100 gallons. 



Whiter Resin Wash. 



Resin, .... 30 pounds. 



Caustic soda (70 per cent.) 9 pounds. 



Fish oil, 4^ pints. 



Water to make, 100 gallons. 



Boil all the ingredients together in twenty gallons of water until 

 thoroughly dissolved, adding hot water from time to time, but not, 

 after the boiling begins, enough to stop it. Three hours will be re- 

 quired for a complete mixture of the materials, hot water to make 

 fifty gallons being gradually added and the mixture thoroughly 

 stirred. After this the balance of the 100 gallons may be added in 

 cold water. 



Lime, Salt and Sulphur Wash. 



Unslaked lime 50 pounds. 



Sulphur, 25 pounds. 



Stock salt, 18 pounds. 



Water to make, 100 gallons. 



All the sulphur and half the lime are placed in a kettle, add 25 

 gallons of water and boil briskly for an hour and a half or until all 

 the sulphur is thoroughly dissolved. The solution, yellow at first, 

 will turn very dark brown, assuming more or less of a reddish tint 

 and will finally change from a thick batter into a thoroughly liquid 

 condition, the product being ordinary sulphide of lime. All the salt 

 is added to the remainder of the lime and the latter slaked, after
