SEED YEARS OP THE WHITE PIKE AS IIDI GATED BY IIATURAL REPRODUCTION 



The fall of 1914, as has heen shown, was a fair seed year for 

 the white pine. By cutting trees and counting the annual rings we find 

 a remarkable uniformity of the various ages of reproduction in this 

 vicinity. We find that in certain years the reproduction was heavy, in 

 other years was lighter, and in still others there was no reproduction 

 what soever. By adding one year to th^/age of these trees ,the year in 

 which the seed for each crop was produced has heen determined. These 

 observations have covered the country about Ithaca quite thoroughly and
