litter, and stratified under two feet of sand. 



cutting them open, none of them germinated during the 50 days of the 

 test. On the other hand, seeds stored in the ground where they were 

 able to absorb a considerable amount of moisture, (as indicated by their 

 change of weight), germinated 

 rather readily and, in fact, some 

 of them had already started to 

 germinate when they Mere dug 

 in the spring. 



Figure 1 shows the storage 

 experiment set up outdoors. The 

 seed frozen in ice and those kept 

 in tight jars were stored in the 

 cold rooms of the poultry de- 

 partment. 



Present indications are that 

 1943 will not be a seed year for 

 the sugar maples in Durham. If, 

 however, a supply of seed can be 

 located next fall, it is planned to 

 conduct another series of storage 

 tests designed to determine some- 

 what more definitely the condi- 

 tions necessary for satisfactory 

 storage of these seeds. As a re- 

 sult of the season's tests, it ap-
