Our mussel fisheries, valuable as they are, might, we 

 have no doubt, be made still more valuable by the intro- 

 duction of some artificial cultivation. Our coast waters are 

 well supplied at present with mussel seed (the free-swiming 

 embryos), they are found year after year settling down on 

 all sorts of suitable and unsuitable submerged objects, and 

 many millions of them every year perish miserably for 

 want of a little looking after. As was recommended in 

 last year's report, simple stakes (bouchots without wattling) 

 should be erected in likely spots, not for the purpose of 

 taking the place of the beds — which are probably better
