THE BLACK REE])- WASP

Where man has felled tlie primitive forest, obliterating 

 nature's labors of half a thousand years, he leaves a wound 

 that is long in healing. Just as a wound in the flesh leaves 

 a scar that stands out distinct from its surroundings, so the 

 forest heals its injury with a new vegetation, distinct from

Abandoning their natural habitat for the advantages

 setting up their abodes in our pen-holders, in spools, nail

To the general rule among Hymenoptera the black

 several pieces of glass tul)ing, thi-ee or four inches long and 

 a quarter of an inch in diameter, about the laboratory. I
