8 CONSTRUCTIVE BEEKEEPING 



3. Moisture in the air. 



4. Depth of evaporation. 



5. Sunshine. 



6. Altitude. 



7. Number of bees. 



8. Fertility and vigor of the queen. 



9. Number of worker cells in the hive. 



10. Size of entrance. 



11. Construction of hive. 



12. Fit of hive parts and cover. 



13. Radiating surface on inside walls of the hive. 



14. Number of honey and pollen-producing plants. 



15. The amount of water in the nectar. 



To show how much harder bees would have to fan at the en- 

 trance to ripen honey in some localities than in others, if they 

 ripened it altogether by ventilation, the depth of evaporation in 

 inches, taken from a map of the Weather Bureau, is here given : 



25 inches, Ontario, Canada. 

 35 inches, Massachusetts. 

 30 inches, Ohio, Northern part. 

 50 inches, Illinois, Southern part. 

 50 inches, Texas, Central part. 



60 to 100 inches, Colorado, New Mexico, Arizona and most 

 of California. 



From this will readily be seen the different conditions under 

 which the bees do their work in different localities, due to only 

 one of the conditions previously mentioned. It is apparent that 

 similar treatments, as regards ventilation, cannot give uniform 

 results in all these places. 



To make the treatments as near uniform as possible and get 

 like results under these different atmospheric conditions, we 

 must follow the way of the bees and make the hive a condenser 

 instead of a ventilator.
