EXPERIMENT STATION REPORT. 529 



It is seen that of the 108 plants and 22 colors represented 

 the plain yellow has much the largest percentage. This is the 

 color of the wild parent, and suggests that the hybrids when 

 left to themselves may drift back to the wild yellow lypt. How- 

 e\-er, much longer time is needed for any conclusion from this 

 experiment.

Experiments With Lawn Grasses. 



The nine plots seeded to grass, and serving as a border to the 

 Experiment Area, have been kept cut with a lawn mow^er dur- 

 ing each season since tSqG. The following table gives the 

 number of the plot, name of grass seed sown and the condition 

 or stand, of each plot in percentage of perfection for each of the 

 past nine years.
