to a times (in rainy seasons more spraying would be required than 

 in dry ones); (3) in no case spray when the trees are in bloom, but 

 always immediately after. 



Paris green is generally recommended as an insecticide. In the case 

 of the red spider the remedy recommended is that of spraying with- 

 clear water and keeping the atmosphere about the plants moist. 



Liquid Paris green, F. C. Harrison {Ontario Agl. College and Exptl. 

 Farm Rpt. 1895, j^P- 1^6, 187). — A report is given of a test of this 

 material, which is said to be a waste product obtained in the manufac- 

 ture of Paris green, and contains a considerable quantity of free acid. 

 The mixture was sprayed upon tomato plants in strengths varying from 



1 part of the insecticide to from 15 to 100 parts of water, and in every 

 case the plants were more or less injured. The solutions were neutral- 

 ized by the addition of lime, and when used in this form, 1 part of the 

 liquid Paris green and lime to 50 parts or more of water, no injury was 

 done the plants. 



The use of the liquid Paris green in strengths of 1 part to 40, 50, 00, 

 and 75 parts of water burned the foliage of ap}>le trees badly. 



The effect of the mixture upon the forest tent caterpillar was tested, 

 and it was found that in strengths of 1 part to 100 parts of water it 

 was very efiicient in destroying this caterpillar. 



Natural history of the bee, ArtPiiiLE (VJpiciilicar, 40 {lS9G),Ko. 12, pp. 428-442, 

 Jigs. 9). — The author coutinues here his popular treatise upon the liee. In this nuui- 

 ber he discusses the functions of the worker. These are the construction of comb, 

 the ri-aring of young, the gathering of honey, i)olleu, propolis, and water, and tlie 

 rearing of queens. Then he discusses the subject of fertile Avorkers, and the habits 

 of bees in general. The iigures illustrate the forms of comb, eggs, larva' in the 

 comb, and covered honey cells.

Wintering, R. Pinzot {UApiciilteur, 40 {1896), No. 12, pp. 450-458). — The author 

 coutiuues the discussion of the subject of wiuterlug, and brings out the fagt that for 

 successful wintering there are necessary (1) strong colonies; (2) sufficient stores; and 

 (3) a hygieuic hive. These subjects he takes up more or less in detail and endeavors 

 to show how one may distinguish a sufticiently strong colony, and whether or not 

 there are sufticient provisions. For the ordinary frame hives he thinks there should 

 be 15 kilos of provisions, although a c(dony might be wintered upon 12. 



Relative to the hive he says it should be constructed of sucli material and be in 

 such a form as to allow the escape of Aajiors and deleterious gases, while at the same 

 time conserving the heat and protecting the bees from too rapid temperature (changes. 

 Ventilation, he thinks, should be at the bottom. 



"Wintering, A. Manjeau {L'ApicvJtenr,41 {1897), No. 1, pp. 7--?^).— The author con- 

 tinues the discussion of this subject between Pinzot and Devauchelle. He summa- 

 rizes the opinions of both and gives his own. Aloug with Devauchelle he is inclined 

 to the opinion that the deleterious vapors of the hive should be gotten rid of at the 

 top rather than at the bottom.

The Union hive, F. Jules {L'ApUuUenr, 41 {1897), No. 1, pp. 16-19).— The author 

 describes a hive in the constructi<m of which he has endeavored to comliine the ver- 

 tical anil horizontal systems. The hive is of suflicient size to allow of 25 i'rames, or 

 of 24 frames and a partition. Dividing it into two parts by the partition, one is
