 which appeared in great numbers on young trees. Flour emulsion, McDougall's 

 insecticide and fungicide wash, V-2 fluid, Niagara brand lime-sulphur wash, 

 target brand fungicide, and wbale-oil soap were tested. Whale-oil soap and 

 McDougall's insecticide proved the most effective, both apparently killing all

Spring losses of bees, R. Beuhne {Jour. Dept. Agr. Victoria, 7 {1909), No. 

 8, pp. 500, 501, fig. 1). — There is said \6 be a considerable loss of bees in the 

 spring in Victoria and New South Wales, due to a disease somewhat different 

 from dysentery and known as dwindle. The bees apparently leave their hives 

 in quest of stores and are unable to return, very largely because of exhaustion 

 and chill in consequence of impaired vitality. This is deemed to be the result 

 of malnutrition in the larval stage caused by a deficiency of protein in the 

 pollen used in the preparation of the larval food.
