on leaves, sheaths, and culms. The streaks were shiny, and the interiors 
of some stems showed an abundance of gummy exudate. In some plants 
the main culms had been killed and were brown and dry, and only 
spindling side culms were living. Other plants showed that the upper 
portion, including the head, had been killed. Specimens of diseased 
plants were collected, but no further work was done. 
In July, 1920, the writer found badly diseased plants of Early Fortune 
(S. D. No. 98) in the plots at Hill Farm, Madison, Wis. (PI. 1, 2, 3, A). 
The seed for the plot had come from the South Dakota station, and the 
lesions were like those described earlier by Doctor Johnson. The plants 
were about 18 inches high and just beginning to head. Narrow, brown, 
water-soaked streaks extended from the blades of the leaves down onto 
the sheaths, and were also present on the culms. Where many streaks 
coalesced on a leaf the tissue was brown and translucent, and there was 
evidence of abundant exudate in the form of thin, white scales along the 
streaks. Similar lesions also occurred on the peduncles and pedicles of 
the panicle. In most cases the infection was not severe enough to kill 
the plants, but individual leaves were partly or entirely browned. In 
some instances the whole top of the plant was killed, the tissue becoming 
soft and brown, especially where partly inclosed and protected by lower 
leaves and sheaths. In such cases new shoots were coming out at the 
base. 
The groups and varieties of millet grown at Madison in 1920 are shown

These millets were grown in a series of adjoining, duplicate rows in 
the following order: Japanese millet, Black Voronezh, Hansen's White 
Siberian, Ainu, Tambov, Early Fortune, Turghai, German (Golden), 
Kursk (Shelley), Kursk, Common. 
The disease developed only on varieties of proso. Early Fortune showed 
abundant infection. A few scattered lesions appeared on Tambov and 
Turghai which grew on either side of Early Fortune. Traces of the 
disease also appeared on Hansen’s White Siberian. The varieties of fox¬ 
tail and barnyard millets showed no signs of infection, although two vari¬ 
eties of foxtail millet were growing beside infected varieties of proso. 
Seed of Early Fortune from Madison, Wis., was sown at Tuxedo, Md., 
in 1921. The season was hot and dry, and only scattered lesions appeared 
on the plants. Seed from this 1921 plot was again sown in a different field 
at Tuxedo, Md., in May, 1922. During May and early June there were 
abundant and almost daily rains for two weeks. Rows of Hansen's White 
Siberian and of Tambov were sown in the same plot. All three varieties 
showed abundant infection with the bacterial disease. Every plant of 
Early Fortune showed more or less infection, and in about 10 per cent
