to the end of May. A larvicide formula suggested by the author is :— 

 Coal tar, 1 pint ; turpentine, 1 pint ; soft soap, 1 oz. ; water, 

 sufficient to make up to 2 gallons. This quantity is sufficient for the 

 effective treatment of 300 gallons of water.

The following insectifuge for working animals is given :— Vinegar, 

 100 grammes ; phenic acid, 2 grammes ; tincture of aloes, 15 grammes. 

 An alternate formula consists simply of a 2 per cent, tincture of aloes. 

 For dipping small animals, the following insecticide may be used : — 

 Sodium carbonate, 50 grammes ; water, 1 litre ; powder of Delphinium 

 sfaphisagria (stavesacre), 10 grammes. An infusion of the powder 

 should be prepared. For rubbing the animals, either a mixture of 

 1 part kerosene in 10 parts of ordinary oil or a decoction of 50 grammes

 1913, New Brunswick, 1914, pp. 698-718. 



Summarising this extensive report, which should be consulted in 

 the original by those interested, the author says that the fly-control 

 campaigns in the city of New Brunswick, and on the College general 

 and dairy farms, have shown : (1) the need of co-operation between the 

 fly-supressing agency and the managers of the premises on which a 

 fly campaign is in progress ; (2) the insufficiency of the Hodge and 

 other fly traps as a complete control ; (3) the impracticability of 

 obtaining anything like a general adoption of the Hodge garbage-can 

 trap and its ineffectiveness as a destroyer of the house-fly, the really 

 serious carrier of infection ; (4) the paramount importance of 

 eliminating the fly-breeding places ; (5) the usefulness of iron sulphate 

 and carbon bisulphide as larvicides ; (6) the effectiveness of sulphur 

 as a destroyer of adult flies ; and (7) the utility of even incomplete 

 work on fly control.
