millet, but they are much smaller. The 

 head is covered with fine, soft hairs, and it 

 produces many seeds. 



Foxtail commences to grow as soon as 

 the soil gets warm, and the seeds, which 

 have great vitality, will germinate under 

 favorable conditions until the arrival of 

 cold weather in autumn. After the cul- 

 tivation has ceased in corn, potatoes, and 

 similar crops, the seeds which lie in the 

 soil will grow when it is sufficiently moist. 

 The plants produced under these condi- 

 tions grow very rapidly and mature seeds 

 in an incredibly short space of time. 



Foxtail will grow on almost every class 

 of soils, but on rich prairie soils it luxu- 

 riates. It infests almost every form of 

 crop grown, but does not give much trouble 

 in rye, winter wheat, or on cultivated 

 meadow, owing to the early period at 

 which these crops mature. It is spe- 

 cially troublesome in cereals sown in the 

 spring, as in these the plants frequently 

 grow in such numbers as to greatly hinder 

 the growth of the crops. 



Foxtail is distributed through the agency 

 of birds, wind and water, and to a still 

 greater extent probably through that of seed
