AMERICAN HONEY PLANTS 275 



ceded by an autumn, winter and spring with more than the average 

 precipitation. 5. A rainy May scarcely fails to precede a good honey 

 season. 6. South wind seems favorable and east wind unfavorable. 7. 

 The yield shows a gradual depression preceding and a gradual increase 

 until about the fourth day following a rainy day, after which it re- 

 mains fairly constant until about the fourteenth day following a rain. 

 8. Good honey months average slightly higher in temperature than 

 poor, this being especially true of the spring and fall months. 9. Clear 

 days are favorable to the production of honey. 10. Yield is best on 

 days having a maximum temperature of 80 to 90 degrees. 11. A wide 

 daily range of temperature is favorable for a good yield. 12. A low 

 barometer is favorable for a good yield. 13. The fluctuations in the 

 yield for a producing period seem to be closely correlated to the 

 temperature range and the barometric pressure, acting jointly. 14. A 

 cold winter has no detrimental effect on the yield of the succeeding 

 season, but a cold March reduces it. 15. A winter of heavy snowfall 

 is, in the great majority of cases, followed by a larger honey yield.
