Grerminating seeds in sawdust, G. ¥.. Stone {Bot. Gaz., 19 (1894), 

 No. 8, ])]). 333, 331). — The author recommends the use of sawdust for 

 germinating seeds. Care n*ust be taken not to use the sawdust of oak, 

 chestnut, or other tannin bearing wood as it will result in tauuiu 

 poisoning of the roots, giving them an abnormal growth. Rather 

 coarse sawdust is preferred to the finer. Seeds may be sown in well- 

 drained pots and watered at least once a day. The roots of sawdust 

 cultures present characteristics in their growth which are closely 

 allied to roots grown in moist air.
