20 Mindeskrift for J. Steenstrup. IX. 



While the hay is consumed directly by the domestic animals and is thus of 

 economical use, the Zostera in the sea must generally first rot, then be consumed 

 by the lower animals which are again eaten by the fishes, before it can be of any 

 use to man. It would therefore be advisable to lay more stress than has hitherto 

 been done on the cultivation of the few lower animals which in themselves are 

 useful animals, such as prawns and edible mussels, or directly make use of some 

 of the over-production of Zostera e. g. for industrial purposes; what has been done 

 in this respect up to the present time is but little, as for example stuffing of 

 mattresses, manure etc.
