The seeds of every species tried and of similar trees are best stored 

 in air-tight vessels in as low a temperature as possible. Hinoki- 

 seeds should be stored in a temperature lower than 10°C. at the highest. 

 No artificial drying of seeds is necessary previous to storing. 



The best place for storing seeds is a cellar so made that the tempera- 

 ture is uniform, for which purpose in Tokyo it is necessary to dig 8-10 

 metres below the surface. The so-called " wind holes " where the people 

 store silk worm eggs found in mountains would serve well for storing of 

 tree seeds.
