Republican Elver and ou tbe npland prairies. It is less objection- 

 able on account of its "spears'* tban Porcupine-grass and Needle- 

 grass. The leaves are softer and retain their nutritious qualities 

 longer. It is well adapted to this section of Nebraska. In Colo- 

 rado it is abundant, not only at an elevation of 5,000 feet in the 

 vicinity of Fort Collins, but near Colorado Springs and Golden it 

 abounds up to an altitude of 8,000 feet. It is one of the most 



valuable forage plants 

 of the foothills. 

 Fowl Meadow-grass {Poa 

 ^ftava) is not uncommon 

 on the flats and along 

 the smaller streams in 

 western and northwest- 

 ern Iowa. It would be 

 of greater value for hay 

 if it could be harvested 

 earlier. lender present 

 conditions of making 

 hay in August it has 

 lost much of its valua- 

 ble qualities. In Colo- 

 rado this species occurs 

 in wet grounds at lower 

 altitudes than lUue- 

 grass. 

 Foxtail or Pigeon-grasses 

 (Cha'tochloa viridis S. »& 

 S. and C. gJmica S. & S.) 

 are abundant through- 

 out central and western 

 Iowa in cultivated fields 

 and in open places in 

 Blue-grass ])astures. 

 Thongh usually re- 

 garded as weeds, they 

 afford some picking in 

 cornfields after the corn 

 is removed. TTndcr 

 these conditions, however, the forage is of very poor (|uality. 

 Giant Rye-grass ( I-Jh/miis eondensatnN) is abundant in Colorado, at an 

 (>levation of 5,000 to 5,500 feet. Cattle seem to prefer the shorter 

 grasses to this large coarse species. Professor Lamson-Scribner 

 speaks of it as an excellent winter forage plant in California. A 

 second species {Elymtis triticoides) was observed in spruce and ])ine 

 woods in Clear Creek Canyon. It is of some value in the sparsely 

 wooded areas of this region of Colorado.
