GRASSES OF IOWA, 



worthy of being extensively tried, especially in meadows at 

 high altitudes. Its cultivation has been carried on to some 

 extent in the northwest, with very promising results. " 



The results of the analysis of the two samples of this grass 

 are given below: 



Sample No. 1. Gathered April 27, 1896, height 12 inches. 

 Sample No. 2. Gathered May 19, 189(>, height 14 to 20 inches.

The water content of the two samples are very close, less 

 than 2 per cent, and on making a comparison of the various 

 constituents of the dry matter, it is found that as a result of 

 the difference of twenty-two days sample 2 has 2.60 per 

 cent less of fat and 4.97 per cent less of protein. The same 

 condition is present in the amount of albuminoids, where there 

 is a difference of 2.44 per cent of albuminoids in favor of sam- 

 ple 1. The amounts of crude fiber in both samples are very 

 close, but the difference of nitrogen -free extract is 9.40 per 

 cent in favor of the sample which was collected last. The 

 amount of ash is largest in sample 1.
