 management of bees would be a work of supererogation.

It is believed that a twenty-acre field of grass, well 

 sprinkled with the flowers of white clover, yields to bees 

 every fine day at least 100 lb. of honey, and strongly 

 scents the air as well ; and that twenty acres of heather 

 in flower yield 200 lb. of honey per day. If this cal- 

 culation is correct (and we think it is), who wiU ven- 

 ture to estimate and give the sum total of aU. the counties 

 of Great Britain and Ireland? We remember being 

 startled at the statement of a citizen of Manchester, in a 

 paper which he read before the British Association for 

 the Advancement of Science, when that Association met 

 in that city some years ago. I forget the title of the 

 paper, but the subject of it was the poisonous exhalations 

 of the town. The number of tons of carbonic acid gas 

 constantly passing off into the atmosphere was named — a
