A uniform weighed quantity of seed was used for seeding each row, 
which was sown by hand until 1918, and since that year with a 
nursery drill. Up to and including 1918 varieties or selections were 
grown mostly in single rows. Since that date they have been grown 
mostly in triplicate, though sometimes with five replications. Agro- 
nomic notes have been taken on emergence, heading, ripening, and 
yield of grain and also on cereal diseases. 
The rows were harvested by hand, and the barleys were bagged to 
prevent loss through shattering after harvest. Other cereals w T ere 
bagged in some years. The threshing was done by a specially con- 
structed thresher. The weight of grain has been recorded in both 
ounces and grams. 
The miscellaneous experiments included wheat breeding, wheat 
classification, and a dormancy experiment with barley. These ex- 
periments have been sown mostly in 5-foot rows 1 foot apart, but 
wider spacing and longer rows have been used at times. Head selec- 
tions or bulk seed have been sown, according to the plan of the ex- 
periment. The seed was spaced or sown in drills by hand or with a 
nursery drill. Where the grain w r as desired, the rows were hand- 
harvested, bagged where necessary, and threshed with a small cyl- 
inder thresher. 
It is neither desirable nor possible to present in this bulletin all the 
data recorded in the nursery experiments. However, a brief state- 
ment of the general results of the experiments with each cereal will 
be given. 
EXPERIMENTAL DATA. 
The object in conducting cereal experiments at Chico has been 
primarily (1) to determine what varieties of the different cereals are 
best adapted to the upper Sacramento Valley and (2) to improve by
