insecticide, but this action is not sufficiently great that its use 

 for this purpose can be recommended. Flea beetles appear to 

 be most easily overcome or driven away by this preparation, 

 and it is possible that it can be used to advantage for this pur- 

 pose when the pest causes much damage. 1 Uniformly good 

 results have not always followed its use for this purpose, how- 

 ever. 



BORDEAUX MIXTURE AND MOLASSES. Ferret mentions the 

 following formula as possessing especial merit : 2 



Copper sulphate 4? pounds. 



Quicklime 4* " 



Molasses 4* " 



Water 30 gallons. 



Dissolve the lime in 24 gallons of water. To this add the 

 molasses, which has been diluted with 3 gallons of water ; stir 

 this well and pour in the copper sulphate, also dissolved in 3 

 gallons of water. The precipitate settles slowly, leaving a 

 greenish colored liquid above. This color is a proof of the suc- 

 cess of the operation. The mixture, even w T hen diluted to 40 or 

 50 gallons, may be recommended for trial, although in this 

 country it will scarcely prove superior to the preparation com- 

 monly employed. Sugar has also been used in place of the 

 molasses.

CARBOLIC ACID; PHENIC ACID; PHENOL; C 6 H 6 O. Car- 

 bolic acid is a powerful poison to the lower forms of life, and 

 is very extensively used as an antiseptic. Its value as an in- 

 secticide or as a fungicide is, however, comparatively slight, 

 and it cannot be recommended for such use. It has been very 

 thoroughly tested however, and the following has been fre- 

 quently recommended for the destruction of root insects : 



Carbolic acid 1 part. 



Water 50-100 parts.
