(16) Seedlings which are small at first frequently sur- 

 pass in growth larger ones of equal age. 



(17) The size and specific gravity of the seeds are more 

 definitely correlated with growth than is the initial height 

 of seedlings of the same age. 



The author wishes to thank Professor Charles F. Hottes, 

 not only for suggesting the problem, but also for his kindly 

 criticisms and helpful suggestions during the progress of 

 the work.
