The material is rich in phosphoi'ic acid and in nitrogen, a circum- 

 stance not often noticed in materials of this kind; its raanurial value 

 is for this reason an exceptional one.

The manurial value of the material compares well with that of the 



average hay from dry meadows. The composition is, in both instances, 



equally liable to serious changes when expo!^ed to the action of 



water.
