726 EXPERIMENT STATION RECORD. 



rogams were experimented with, the plants being grown in various 

 conditions of light. In different experiments plants were experimented 

 with from the seedling stage to rather more mature condition. In 

 addition to the flowering plants, experiments were conducted with 3 

 species of Mucor, some chromogeuic bacteria, a motile bacillus, and a 

 species of Oscillatoria. In the various experiments it was seen that 

 the plant tissues absorbed the Eontgen rays quite freely, but there 

 was no marked influence on the growing parts. There were no visible 

 external injuries, even wheu the plants were exposed at close range 

 for the greater part of the time during several days. 



Report of the botanist, C. E. Bessey (Nebraska State Bd. Agr. Bpt. 1896, pp. 79- 

 P5j._Tho author reports on the progress of the botanical survey of the State of 

 Nebraska, and states that now more than 3,200 species of plants are known to be 

 natives of the State. Popular notes are given on pasture, hay, fodder, and silage 

 plants; root and soiling crops; and grains. The culture and use of alfalfa, con- 

 sidered "without question the great forage plant of the Plains," are noted at 

 length.
