1 These data were taken at the time the last picking was made. By the end of the growing season, October 15, the plants had greatly increased in spread and also somewhat in 
height. This was due largely to the new fall growth. 
2 In 1912 this plant did not appear above ground until August 1. 
* This plant was dead in 1912.
