■that trees from temperate zones, fail to flower, and the flowering time of 



indigineous plants falls in the dry season. Again the practice of 



P 



pruning roots to induce flowering means a reduction of water su^ly or 



the formation of water conducting tissue; on the other hand pruning the 



P. 

 shoots thereby increasing the water su;^y reduces flowering," 



"Prof .Loew.of Tokiovoonsiders sugar the flower-forming material, 

 and light .temperature, increase and diminution of water supply favor its 

 formation, the latter concentrating the sugar in the plant;hence the rem- 

 arkahle flower show of cheeries and plums in Japan, where the climate is 

 the cause of the fall of fruit before ripening, which induces the deposit 

 of the unused sugar as starch and fats in the bark and this concentration 

 accounts for the profusion of flowers (152 flowers on 10 inches of shoot 

 ^ere counted)" 



"These considerations may give a clue t6 the prediction of 

 $eed years even in forest trees." 



The above is interesting in the fact that in the main points 

 it s-upports the theory that seed production is influenced by the 

 available water and temperatures. 



SEED DISTRIBUTIOI OF THE WHITE Pllffi. 

 The observations on seed distribution as to direction and dis- 

 tance from the seed trees have been made in stands in and about the 

 Cornell University woodlots and also in a number of stands in the 

 ■surrounding country. Each stand will here be taken up separately. 



VETBEIHAEY WOODS. 

 This woodlot is situated on the south east corner of the 

 University Farm, on the south side of the Slaterville road, at the bottom 

 of a steep north slope. The soil is a clay loam and very rocky. More or
