 birds that feed upon it, as the children go to and from

 on the front border of the fore- 

 wings. The males and females 

 may be found about the time cur- 

 rant leaves open in the spring, and 

 a few days after, the white eggs are 

 placed end to end along the veins 

 on the underside of the leaves. I 

 have been informed that a pair of 

 black and white creeping warblers 

 kept one row of currant bushes so clean that the box 

 of white hellebore, provided against them, remained

The Rose Slug, Monostegia roses. — This familiar pest

 night, remaining hidden beneath the leaf during the day. 

 The rose bushes appear as if scorched and are greatly
