A REPORT ON AN INVESTIGATION OF WEEDS FOUND ALONG 
HIGHWAYS, FIELDS AND MEADOWS OF THE STATE 
UNDER THE DIRECTION OF THE STATE 
DEPARTMENT OF AGRICULTURE. 
I beg leave to make the following report concerning an investigation 
of weeds along highways. 
Shortly after the last session of the legislature the committee met on 
call of Governor Packard in the office of Prof. C. F. Curtiss, at Ames, 
and agreed upon sending out a circular. Thereupon Professor Curtiss 
of Ames sent out a circular of inquiry in regard to weeds to super- 
visors and others in the state. The answers received to the circulars 
have been most satisfactory. In addition to this circular the writer 
has been in communication with hundreds of farmers in the state on 
this topic and he has utilized the information received from farmers in 
preparing this report. 
The circular sent out by Professor Curtiss contained the following 
queries: ^ j 
1. Are any of the following named weeds, or other weeds that are 
difficult to kill, found in your vicinity? Please check those that occur or 
add the names of others: 
Quack Grass, Wild Mustard, Canada Thistle, Wild Oats, Sweet Clover, 
Clover Dodder, Alfalfa Dodder, Field Dodder, Cowbane, Corn Cockle, 
Squirrel-tail, Marsh Elder, Cocklebur, Curled Dock, Smooth Dock, Horse 
Nettle, Jimson Weed. 
2. If there are any noxious weeds in your vicinity, of which you do 
not know the name, please send samples to Prof. L. H. Pammel, Ames, 
Iowa, for identification. 
3. Are the weeds you have named found in the highways? Railway 
right-of-way? Private grounds? 
4. What methods that have been used to eradicate these weeds have 
failed? 
5. What methods have been used successfully?
