attempt to breed a five-leafed race of the crimson clover 
(Trifolium incarnatum) analog- 
ous to the five-leafed race of the 
red clover (Trifolium pratense) 
which has already been described 
( 5, p. 36). I started the ex- 
periment in 1894; since then I 
have devoted a great amount of 
trouble to the task without any 
result, until in 1900 I gave it up. 
The attempt simply does not suc- 
ceed, with my material at any 
rate. 
The object was worth a great 
effort. At first I believed that 
I had artificially made the five- 
leaved red clover, or as it is 
often expressed, that I had cre- 
ated it. The gradual develop- 
ment of my theory, however, led 
me to doubt the correctness of 
this opinion. It seemed possible 
that I had merely found the race 
already existing in nature, but 
in a condition in which it was 
not recognizable as such. Eight 
years however had gone by since 
the beginning of that culture, 
and it was practically out of the 
question to go back to it. I re- Tig-. 44. Trifolium incar-
