14 The Colorado Experiment Station 
“Each of the various types of injured grains, as pink-colored, black- 
pointed, white-bellied, etc., breed true, reproduce themselves. Certain 
conditions of soil, weather and variety, however, seem to largely affect 
the development of these features.” 
It is certainly difficult to reconcile the conclusion of the former 
publication of this station, North Dakota, with the statement just 
made, for in the conclusion drawn from previous work the same 
author says: 
“From the results (of experiments made.—H.) the author believes 
that the white spots are not due to crossing nor are they matters of 
heredity, but that this peculiar mottling is due to the action of moisture, 
air and sun upon the grain while it is yet in the chaff.” 
It is possible that the author had reason for changing his opin¬ 
ion before writing Bulletin 107, North Dakota Experiment Station. 
If so, he failed to state the reason or even to take any cognizance 
of the statements of the earlier bulletin. In a lecture delivered 
before the agricultural students of the University of Wisconsin, 
which appeared in Science, July, 1913, he maintains, or rather 
asserts, the findings of the later bulletin. The author may have an 
object, worthy and well advised in North Dakota, but it is not ef¬ 
fective in shedding light upon the question that I have in hand, 
though he evidently includes the condition of yellow-berry as con¬ 
stituting a symptom of deterioration. 
The four bulletins from which these statements have been given 
constitute about all of the literature to be found in our station 
publications touching upon yellow-berry. 
I am not at all sure that the California bulletins on the wheats 
of California have this question in view at all. A white wheat is 
by no means a diseased wheat or an abnormal one, though at times 
it would seem almost as though they were really describing wheats 
which were so badly affected that every kernel was mealy or 
starchy. These wheats are spoken of by some as white, soft, 
starchy wheats. Dr. G. W. Shaw and A. J. Gaumnitz describe 
White Australian as follows: 
“Grain large, long, plump, white, soft, opaque, starchy interior: 
Little Club, grain medium large, short, white, irregular in shape, very 
soft and starchy interior; Sonora, short, round, plump, white starchy 
interior.” 
It would be difficult to give a better description of kernels of 
our wheats wholly affected by yellow-berry. I may be mistaken, 
but I do not understand the California bulletins to deal with their 
wheat as diseased or deteriorated wheats, but that they consider 
these wheats as normally white, soft wheats. If they consider them 
abnormal wheats, diseased wheats, they assign no cause, and sug-
