WATER ABSORPTION OF FLOUR. 
Water absorption of the flour from 60 samples of Marquis wheat 
grown at 12 experiment stations in the western United States during 
the five years from 1917 to 1921 is shown in Table 6. The data show 
that the individual samples vary in water absorption from 52.9 per 
cent from a sample grown at Chico,, Calif., in 1919, to 67.1 per cent 
from a sample grown at Aberdeen, Idaho, under irrigation in 1920. 
The average for -the 60 samples is 60.1 per cent water absorption. 
There was little difference in the average from all of the stations 
for the different years. Samples from Chico, Calif., show the lowest 
water absorption, averaging only 56.8 per cent, while those from 
Havre, Mont., had the highest absorption, averaging 61.8 per cent. 
The influence of both season and locality on water absorption is very 
marked, as is indicated by the number of high ranges in percentages 
for the samples from the individual stations and between stations for 
the individual crop years. The highest range for a station was 10.9 
per cent for Aberdeen, Idaho, and the highest range for the crop 
years was 11.8 for the 1919 crop.
