It will be seen from the table that in composition these sea- 

 weeds compare very well as a food with either corn fodder, corn 

 silage, or rye fodder. "While there have been no experiments 

 upon the digestibility of these materials, because of the small 

 amount of woody matter (fiber) in the seaweeds, it is fair to 

 assume that they would be more readily and completely digested 

 than the ordinary cereal green fodders. 



SEAWEED AS MANURE. 



The Station has analyzed the two specimens above described 

 with reference to the manurial value with the following results :

The Rhode Island Experiment Station made quite a thorough 

 study of the seaweeds of that state, and published the results in 

 bulletin 21 of that Station, which is by far the best treatise on 

 seaweeds and their use yet issued. The figures in the following 

 table are derived from that bulletin. For the sake of comparison
