The weed belt has Ijeen coutinucd for seven years without iuter- 

 fereuee iu any wa}' — that is, phmts have spread by roots, seeds have 

 ripened and fallen, germinated and grown as they might be able in 

 the fierce struggle with other kinds. It is needless to state that the 

 ground has been occupied, and so to say two or more crops of plants 

 have been made during the season, for some weeds are early in com- 

 ing to the front and others delay until near the close of the season. 



The following is the list of fourteen species that have been the 

 most prominent during the year, arrayed in the order of their aggres- 

 siveness, the worst appearing at the head of the list and the least 

 objectionable at the foot. Those weeds that were in the list for 

 previous years, with their rank, are given in the tabk'. Thus it is 

 seen that in 1S9T only five of the present list were then much in 

 evidence, and, for example, the wild carrot was then twelftli on the 

 list, while now it is second in rank.
