and Water ; 2. Copperas Water ; 3. Ammonia Water ; 4. Tar Water. 

 The last three proving ineffectual were not tried here, but the Car- 

 bolic Acid was reported as being quite successful and so was repeat- 

 ed at this Station this summer. 



EXPERIMENT I. CARBOLIC ACID. 



One part of Carbolic Acid to sixty-four parts of water. About 

 three table-spoonfuls were applied to each hole. 



Result. — One day later no ants could be found and the hills showed 

 no signs of fresh work. The following day, however, fresh dirt 

 was present around the holes, and ants were seen at work. 



The grass near was killed by the solution. 



EXPERIMENT II. CARBOLIC ACID. 



One part of Carbolic Acid to thirty-nine parts of water. About 

 three table-spoonfuls were applied to each hole. 



Result. — This stronger solution seemed to have even less effect 

 than the solution tried in Experiment I. The grass was killed as in 

 the other case. 



Why these experiments, which were a success in Indiana, should 

 fail here I cannot say. The injury done the grass, however, would 

 render this an undesirable remed}' even if successful so far as re- 

 moving the ants is concerned. 



EXPERIMENT III. KEROSENE. 



The kerosene was poured on in sufficient quantity to moisten the 

 entire hill. 



Result.^'rhe nests were deserted and the ants either destroyed or 

 driven away. 



The grass around was killed, however, which makes this an un- 

 desirable remedy also. 



BISULPHIDE OF CARBON. 



This disagreeably smelling chemical may be obtained of any drug- 

 gist at about fifty cents a pound. The bottle in which it is contained 

 should be kept tightly stoppered, as it loses its strength if exposed 

 long to the air. When used, care should betaken to avoid breathing 

 the fumes, not only, because these are disagi-eeable but also because 

 when breathed for some time the health is affected. It should also 

 be kept away from fire as it burns at 107° Far. 



EXPERIMENT IV. BISULPHIDE OF CARBON. 



Eight or ten drops poured on the top of the hill.
