Aim 'in r: Cultures of Uredixeae ix 1909 



whole paragraph beginning with the third line on page 242 of the 

 last season's report is largely irrelevant, and should be stricken 

 out. 



Most of the experimental part of the culture work of each 

 year is done in the spring, and while in progress it wholly ab- 

 sorbs the time of one person in addition to that of the regular 

 workers in the department. This year Miss Louise M. Falk, of 

 Davenport, Iowa, a senior honor student in the University of 

 Iowa, was recommended for the position by Professor Thomas 

 1 1. Macbride. Miss Falk was in charge of the work from April 

 1 to June 3, She showed great enthusiasm and assiduity in con- 

 ducting the cultures, although the turmoil of building and moving 

 put the possibility of entirely satisfactory manipulation out of 

 the question, as well as introduced most annoying interference. 

 As for the year or two past, most of the cedar rust cultures were 

 made by Mr. Kern. The investigations as a whole are a part 

 of the work conducted by the botanical department of the In- 

 diana Experiment Station, and are financed from the Adams 

 fund appropriated by the general government for scientific re- 

 search. 



Those who assisted this year by supplying culture material 

 and communicating field observations are most gratefully men- 

 tioned. Mr. E. Bethel, Denver, Colo., heads the list with forty- 

 six collections of culture material. Messrs. J. F. Brenckle, 

 Kulm. X. D., J. M. Bates, Red Cloud, Neb., and W. P. Fraser, 

 Pictou, Xova Scotia, each sent between twenty and thirty collec- 

 tions, while a much smaller number was sent by Messrs. O. E. 

 White, Brookings, S. D., A. O. Garrett, Salt Lake City, Utah, 

 C. F. Baker, Claremont, Calif., J. J. Davis, Racine, Wis., E. 

 Bartholomew, Stockton, Kans., E. W. Olive, Brookings, S. D., 

 John L. Sheldon, Morgantown, W. Va., F. D. Heald, Austin, 

 Texas, H. W T . Barre, Clemson College, S. C, W. P. Kelley, 

 Honolulu, Hawaii, F. E. Lloyd, Zacatecas, Mex., Aven Nelson, 

 Laramie, Wyo., F. L. Stevens, West Raleigh, N. C, and Guy W. 

 Wilson. Fayette, Iowa. Plants for particular culture work were 

 sent by Dr. William Trelease, of the Missouri Botanical Garden, 

 St. Louis, Mo. Thanks are extended to the above individuals, 

 and to others who aided in the year's investigations.
