62 HATCH EXPERIMENT STATION. [Jan.

 factory. 



3. Stop Fly. — Applied as spray. Favorable effect dis- 

 appeared in one-half hour. 



4. Norwood Sanitary Fluid. — Applied as spray. This 

 material is unquestionably crude creolin ; it is ver}^ valuable 

 as a disinfectant, but riot satisfactory as a fly remover. 



5. Flylene. — Very effective, keeping the flies oft' for a 

 long time.

 fective in keeping off small flies, but not the large house fl}'. 



7. Eli Fly Chaser. — Applied with brush. Same as 

 No. T).

 short time. One year's trial.

Tests vnth Other Substances. 



11. Light Coal Tar Oil. — This is the lighter of the two 

 oils derived from tar. It was obtained through the courtesy 

 of the Pocahontas Collieries Company, Pocahontas, Va. It 

 appears as a dark, thin oil, with a strong creosote odor. It 

 was applied as a spray, and gave quite satisfactory results. 



12. Recommended by J. M. W. Kitchen, 31. D. — One 

 pound resin, one-half pound caustic potash, two pounds 

 whale oil soap (chipped), two quarts water. Boil these 

 until all united into a smooth liquid, then add one pound 

 })ine tar and one pint kerosene. Thin down if necessary 

 with water and kerosene. This mixture was quite thick and 

 heavy. It was applied lightly with a brush, but was not 

 effective. 



13. Recommended. — One-half tea cup bi-sulphide carbon, 

 in which dissolve one tablespoonful pine tar, stirring thor- 

 oughl}^ until tar is dissolved, and then add one quart kerosene 

 or crude petroleum, and apply as a spray. This mixture was 

 quite effective for a few hours, until the carbon bi-sulphide 

 had evaporated. It must be kept in glass-stoppered bottles.
