David F. Day had collected it "near the cattle-yards at East 

 Buffalo; along the railroad tracks at Toledo, and by a roadside, 

 40 miles west of Milwaukee." (17) In a paper on "Recently 

 introduced plants in and about Rockford, 111.," M. S. Bebb states 

 that ^Lactuca Scariola was limited with us, for a few years, to 

 a single patch on the embankment near the station house." (18) 

 Aug. E. Foerste reports it as "quite abundant at Dayton, O.: 

 already a pest at Put-in-bay; 3-5 specimens at Lincoln, 111." (19) 

 Other notices are: Cleveland, O., in 1882 (20); railway at Pains- 

 ville, O. (21); Union county, Ind. (22). 



Yet as late as 1889 it was still rare in places. In that year 

 E. J. Hill reports: "I first noticed this plant in the summer of 

 1895, in the corner of an abandoned vegetable garden, and in 

 the adjacent street, at Englewood, 111. It has since spread along 

 the street for a couple of blocks, and is well established. I have 

 not seen it elsewhere in the vicinity of Chicago." (23) 



Its westward progress still continued, and it soon reached 

 Minnesota. Here, according to E. P. Sheldon, Minn. Bot. Stud- 

 ies 1: 80, "the first plants were noted and collected in 1892, on 

 the river bank, near the University, Minneapolis. During the 

 summer of 1893 ^ spread so as to become a common weed in 

 the neighborhood of Minneapolis and St. Paul." Notices of its 

 appearance elsewhere in Minnesota may be found in ib. 1: 409; 

 1: 626; 2: 192; 2: 574. In Iowa in 1895 ^ was sufficiently 

 common to be one of the "two common weeds" which supplied 

 the subject for a paper by L. H. Pammel in Bull. 28, Iowa Agr. 

 Exp. Station. It is also mentioned by Fitzpatrick, Fl. Iowa 

 100. 1899. 



In the Rocky mountain states it appears to be less com- 

 mon. Only a single locality in each is reported from Montana
