to April I was — 5° C. A second part was also placed in unsealed jars 

 and deposited in an ice-box, where the temperature varied from i° to 

 8° C. The relative humidity averaged about 95 per cent. A third part 

 was dried at a temperature less than 40° C. until the fruits had lost 

 about 5 per cent of their original moisture, when they were placed in 

 closed but unsealed jars and deposited in a room where the temperature 

 averaged about 22° C. and the relative humidity about 47.5 per cent. 

 The fourth part was stored in closed jars and subjected to the same 

 condition as part three. 



Ten fruits of each species from each of the four parts were planted 

 in the greenhouse each month from October to April, under conditions 

 favorable for germination. The average percentage of germination was 

 as follows : 



Pit Ice-box Dried Untreated 



Percent Percent Percent Percent 



Hickories 83 88 41 37 



White oaks 77 87 62 45 



Black oaks 81 99 18 29 



The average germination per cent of the seeds stored in the pit and 

 ice-box were fairly constant for each month from October to April 

 and gave the highest percentage of germination, although those stored 

 in the ice-box gave a slightly higher per cent than those in the pit. 



The germination per cent of those stored dry and untreated, not only 

 gave a much lower average germination per cent, but the viability 

 steadily decreased from October to April and in many species dropped 

 to zero in two to three months after storage.

A committee composed of foresters and rail- 



Protection way officials recently submitted to the Swedish 



from Raihmy Riksdag a report^ on means of controlling forest 



Fires in fires originating from railroad locomotives. The 



Szveden following is of interest to American foresters: 



During the period from 1876 to 1914, 130,438 



hectares^ of public forest were burned over. Private lands bring the 



established total up to 500,000 hectares. In 1914, which is considered 



one of the worst years, 6,447 hectares, representing a money value of 



1,500,000 kroner, were burned. In this year 740 fires started along the
