In recent years, owing to the high price of Swedish pine seed, 

 it has been the practice among some dealers in spite of the high 

 tariff to import German pine seed and sell it as the Swedish 

 article. In order to protect the public against such frauds the 

 Government has adopted a system of coloring all imported con- 

 iferous seed. This coloring is accomplished by injecting an 

 alcoholic solution of eosin into the seed sacks, at sufficient close 

 intervals to color approximately 15% of the contents. 



It has been found that the eosin solution, through the action of 

 the alcohol, reduces the germination per cent, in various degrees. 

 Fresh seed is less affected than old seed. Considering the fact 

 that only 15% of the seeds in a sack are actually colored, the 

 actual loss through the treatment was found to be only from .6 

 to 3.6 per cent, for four different species of coniferous seed 

 tested. 



On April 4, 1910, a proclamation was issued by the King, re- 

 quiring that all foreign seeds of the genus Pinus, excepting P. 

 cenihra and P. siberica, and all species of the genus Picea, may 

 be imported only in sacks marked plainly on the outside with 

 the words "Foreign Seed"; and further, that all such seed must 

 be treated with the eosin solution in accordance with a prescribed 

 method. G. A. P.

account of its adaptability to less favorable 



sites and more rapid growth than the native oak, both in rate of 



growth and quality excelling on such sites. The older plantation, 



on run-out oak-coppice soil, now 47 years old, showed in 1907, 



when 42 years old an average height of 57 feet and diameter of 5 



inches with 4,000 cubic feet to the acre. Thinnings in 1905 



brought over 10 cents per cubic foot. In spite of frost, the 



species outgrows the native oak.
