2 CONTRIBUTIONS TO WESTERN BOTANY? 
Determinative Evolution. 
In a recent ‘issue of Science, vol. 74 p. 559, Osborn of the*N.Y° 
Nat. Hist, Museum, broaches this subject a kind of discovery of 
the laws in the case. V. A. Noyes an . A. Margenau, same 
vol. pp, 595-6 take exception to Compton’s suggestion along the 
same line (,‘*The Uncertainty Principle‘‘) in chemistry. Osborn 
says that there has been creative (‘‘determinative‘') evolution in 
wnimals and heralds itas new in science. In 1923, in my revision 
of Astragalus, I brought out the fact that evolution is due to 
ity. It has been held for ages that God created all things. But 
the great question now is ‘S What kind of a god wasit ?* The 
student of plant breeding finds that plants, under stress of certain 
conditions *‘sport*‘ in all directions, like a blind man feeling his 
not object to honest criticism, none others need be feared. That 
stupidity reigns everywhere in Nature is a self-evident fact toa 
man with his eyes open. 
Burbank was not much of a scientist, for had he used the known © 
factors in plant develdment he would have got the same results in 
half the time. Ha . aaakeeeel
