cylinder lying close to the bark. The disease is most conspicuous in the largest 
roots, but the smallest fibers, upon close examination, are seen to be similarly affected. 
In cases where the woody cylinder is blackened before the adjacent bark shows injury 
the smaller feeding roots passing from the diseased wood through the still healthy 
bark die, being either directly infected by the wood connecting the two, or succumbing 
first and then conveying infection to the main root. 
R. E. B. McKenney, of the U. 8. Department of Agriculture, called attention to 
the fact that the same disease is undoubtedly present in other sections of the country 
where tobacco is grown. 
M. A. Carieton, of the U. S. Department of Agriculture, gave a brief discussion of 
the methods of keeping records and notes on the work in cereal investigations. Sev- 
eral blank books used for the purpose were exhibited. The plans adopted systema- 
tize the work of note taking and record keeping and appealed to those present as 
being a remarkable advance along these lines. 
The following paper, prepared by L. H. Pammel, of Iowa, was then read by the 
secretary : 
Botany in the Agricultural Colleges. 
The committee on methods of teaching agriculture, in its several reports made to 
the Association of the American Agricultural Colleges and Experiment Stations, after 
considerable study, has made certain recommendations with reference to the amount 
of work to be done or required of students taking the four years' course in agricul- 
ture. In the second report" the committee makes the following suggestion as to the 
total number of hours required in the four years' course, allowing fifteen hours per 
week for thirty-six weeks, with ten hours laboratory work or practicums, making a 
total of three thousand six hundred hours: 
Hours. Hours. 
Algebra 75 Psychology 60
