Also, if allowed to stand after it is fully ripe, Early Baart shatters 
more than does White Australian. These two factors may limit 
the further distribution of Early Baart wheat in California. 
The agronomic data obtained from growing Federation, Hard 
Federation, and White Federation in comparison with commercial 
wheats at Chico in 1918 and 1919 are presented in Table V.

In 1918 only enough seed was available for sowing single plats of 
Hard Federation (C. I. No. 4980) and White Federation (C. I. No. 
4981). These results, therefore, are not. strictly comparable with 
those obtained from other varieties, but the exceptionally high 
yields obtained are striking. The yields from both wheats are 
about twice those obtained from White Australian and Early Baart, 
the principal commercial varieties. The Federation outyielded 
Hard Federation by nearly 5 bushels per acre. 
In 1919 Federation (C. I. No. 4734) was included in the experi- 
ment, but only one plat was grown. The yield from this plat 
exceeded the average yield obtained from the four plats of both 
White Federation and Hard Federation. White Federation out- 
yielded Hard Federation with a difference of 2.3 bushels and out- 
yielded the White Australian variety by 4.6 bushels per acre. 
Because of a poor stand the yields of Early Baart were reduced by 
probably 8 to 10 bushels per acre. Comparison with it, therefore, 
is not possible. 
In the two years 1918 and 1919 White Federation had an average 
yield of 43.4 bushels per acre, Hard Federation producing an average 
of 3.6 bushels less. They have both outyielded the commercial
