additional facts determined with regard to its spread through the 

 United States and its dependence upon the prevailing characteristics 

 of the weather. 



As usual the work with weeds has been the identification of foul 

 stuff in commercial seeds and the observations upon the weed plot, 

 which has been maintained for several years in a wild condition. 

 The finding of broom rape upon clover and another species upon 

 tomato are some of the weed events of the year. 



A new greenhouse, 24 by 80 feet, was used for the first time last 

 winter, and in it some results were obtained in germination, particu- 

 larly as to albinism in corn, the dimorphism in buckwheat and the 

 checking of mildews with various fungicides. 



Some studies were made of the dodders, which as parasitic plants 

 are often serious pests to clover, flax and other field crops. 



One bulletin has been issued from this department since the last 

 annual report was published ; namely, June 1st, 1901, Bulletin 151, 

 "Bean Diseases and Their Remedies," with four page plates, nine 

 figures and twenty-eight pages. 



The Station Herbarium has grown with the usual annual accessions 

 from various sources. 



In its many details the work at the Experiment Area and in the 

 greenhouse has been, as formerly, in charge of Mr. J. A. Kelsey, and 

 any success in results in crossing and spraying is largely due to his 

 faithfulness. 



The Experiment Area. 



In the accompanying plan. Figure 1 shows the method of plotting 

 the two acres known as the Experiment Area ; it also locates in the 

 plots the various crops that have occupied the ground the present 

 season. 



The seven series from to VI. run up and down a slight incline of 

 the field and are separated by four-foot paths, while the four plots, 

 33 by 66 feet, in each series extend right and left of the plotted 

 page.* 



To improve the soil, naturally a gravelly clay underlaid with yel- 

 low gravel, stable manure at the rate of twenty tons per acre has 

 been added each spring during the past seven years. Last autumn 

 nearly all the plots were sown to rye after the regular crop was re- 

 moved. This made a good live cover that helped to hold the surface 

 soil from washing in winter, but grew too rapidly in the spring, so 

 that barley is used instead this season. 



* The plotting is given in full detail in the report for 1894, p. 279.
