We have been unable to find any data upon wire grass 

 (Juncus Balticus). The digestion coefficients of two samples 

 of Black grass (Juncus bulbosus and Juncus gerardi) are 

 given by Jordan & Hall, Bulletin 77, U. S. Department of 

 Agriculture. These are given below:

Juncus gerardi corresponds in general appearance and 

 habits more nearly to our wire grass. These are not given 

 as a comparison, but it shows that the digestion coefficients of 

 the native hay of this class grown here are higher than the 

 coefficients as given for other species of pure Juncus.
