growth, cutting the first crop when most of the eggs are laid (about 

 mid-]\Iay), and brush -dragging the field. A lucerne field should never 

 be maintained for more than seven or eight \'ears in an infested 

 district. An arsenical spray is giving excellent results. 



The second generation of the codling moth [Cydia pomonella] 

 in Utah is ten or more times as large as the first. The importance of 

 the first spray is therefore obvious, and poison thoroughly applied 

 in June will kill 90 per cent, of the larvae that would otherwise 

 enter the calyx in August and September. Banding is also important 

 during the life of the first generation. 



For curly leaf of sugar-beets caused by the leaf-hopper, Eutettix 

 fcnella, early planting, and, in some districts, early and frequent 

 irrigation, are recommended [R. A.E., K, vi, 4801. 



Act of the General Assembly [Pennsylvania] No. 58, 6th April, 1921. 



[Received 14th November 1921.1 



This law, relating to apiculture, and the sale, transportation, etc., 

 of bees, honey, hives, and appliances, provides for the inspection of 

 apiaries, the prevention, control and eradication of contagious and 

 infectious diseases among bees, and the establishment of quarantines, 

 and prescribes the style of hive to be used after 1st July 1923, imposing 

 certain duties on persons engaged in transportation, and providing 

 penalties and appropriations therefor. 



While the Act gives ample powers to prosecute offending apiarists, 

 it is hoped that these will seldom need to be enforced, as the inspectors 

 go out in the capacity of advisers, educational methods being used to 

 impress upon those not familiar with foul-brood and other serious 

 apiary diseases the necessity for immediate sanitary methods to ensure 

 health}' colonies.
