GLEANINGS IN BEE CULTURE 



The Best from Others. — Continued rrom Page 171. 



water was obtained from two to twelve 

 months after the death of the colonies, and 

 Mr. Tinsley concludes that the disease or- 

 ganisms probably have little vitality out- 

 side of the bee's body, and are probably 

 killed by exposure to the air. Honey from 

 diseased stocks produced no effect when fed 

 to healthy colonies. Other experiments were 

 also tried, but with inconclusive results. 



Prevention and Cure. — Mr. Tinsley, how- 

 ever, believes the experiments at this re- 

 search apiary proved the disease to be high- 

 ly contagious, and he believes that beekeep- 

 ers should disinfect hives and appliances in 

 any way connected with the disease. He 

 advises a thoro scraping of the hives, wash- 

 ing with a strong solution of formalin, of 

 fumigating with formalin candle, disinfect- 

 ing the ground near the hive with chloride 

 of lime, destroying combs of brood, and dis- 

 infecting frames and empty combs. 



Izal, bacterol, dioxygen, phenol, quinine, 

 formalin, sulphur, milton, flavine, and aper- 

 ients were all tried on colonies already af- 

 fected, but none effected a cure. The best 

 results were obtained with a pure culture of 

 Bacillus BulgaricuH — an organism that acts 

 as a scavenger of the intestines, and dis- 

 places putrefactive and injurious organisms. 

 This culture was mixed with syrup and fed 

 to healthy colonies by spraying. When ap- 

 plied, about one-third of the population was

We want every garden grower to know just how this marvelous machine will make 

 his work easier and increase his profits. So we have prepared a book showing 

 photographs of it at work and fully describing its principle. Explains how / 

 steel blades, revolving against a stationary knife (like a lawn mower) / 

 destroy the weeds and at the same time break up the crust and clods / 

 and pulverize the surface into a level, moisture-retaining mulch. / BARKER
