Weeds Along the State Highway. — The problem of eradicatino' the 

 noxious weeds along the publie roads has been a difficult one for a 

 good many years. It is not right to order a farmer to eradicate nox- 

 ious pests from his land when the neighboring roads are allowed to 

 go uncleaned. The county commissioners have realized this and have 

 done their best to force the county supervisors to do their duty. They 

 have continued, and I believe rightly, to enforce the law on the farmer 

 and orehardist believing that half a job is better than no job at all. 



With the advent of the state highways the question of weed eradi- 

 cation was again brought up. The Highway Commission has shown a 

 great interest and a willingness to co-operate in every way with the 

 clean-up work. During the summer they have kept men busy cutting 

 the noxious growth and burning trash. They have recently taken up 

 the problem of complete eradication of certain of the most noxious 

 weeds, such as morning glory and the thistles. The first experiment 

 along this line is now beinsr tried in Orange County, and crude oil or 

 petroleum is being used. We will watch the results with a great deal 

 of interest, as any means of eradication which will be efficient and at 

 the same time economical, will be of value to the whole state. 



We do not believe that all weeds along the roads should be killed. 

 In the spring they are good to look at and also their roots serve to hold 

 the soil of embankments in place. We believe, however, that all w^eeds 

 should be cut during the summer to remove their unsightly appearance, 

 and especially that all noxious weeds should be absolutely eradicated. 

 We wish to express our thanks to the State Highway Commission for 

 the readiness they have shown to co-operate in this work. — 0. W. New- 

 man.
