patches so thickly as to cover all the plants. In the experiments 

 carried on at the Vermont Agricultural Experiment Station by 

 Professor Jones, it was found that as large a quantity of salt as 

 eighteen pounds to the square rod may be used without serious 

 injury to the grass ; indeed the grass soon becomes all the finer 

 when relieved of its crowding competitor, for the weed so smothers 

 and "runs out" the grass that it does much more harm than a 

 temporary check in growth from the salt treatment. 



Plants in roadsides and waste places should be looked after and 

 destroyed. If possible, the sentiment of an entire neighborhood 

 should be aroused against Orange Hawkweed, for, with a plant of 

 this quality, the careful farmer is largely at the mercy of any 

 slovenly cultivator who chooses 

 to be regardless of communal 

 welfare. 



FIELD HAWKWEED 

 Hieracium pratense, Tausch. 



Other English names : King Devil, 

 Yellow Devil. 



Introduced. Perennial. Propa- 

 gates by seeds and by stolons. 



Time of bloom : June to August. 



Seed-time: July to September. 



Range : Eastern Quebec to south- 

 ern New York. 



Habitat: Fields, meadows, road- 

 sides, and waste places. 



Not many years have passed 

 since this immigrant from Europe 

 landed in this country; its range 

 is not as yet very extensive and 

 it is to be hoped that it may not 

 increase fast or far. Cattle re- 

 fuse to eat the plant because of 

 its bristly foliage and nauseous, 

 bitter juices.
