VI PREFACE. 



pisciculture capable of endless development alike in 

 salt-water and in fresh, it is marvellous that multi- 

 tudes should be pining with hunger in a land like 

 ours, literally set in an ocean of plenty. 



The interests of the public economy, as well as of 

 large sections of our "maritime communities, are so 

 deeply implicated in oyster and mussel culture, and 

 in the judicious prosecution of fishing for herring and 

 salmon, that no regret is felt for the time expended 

 in making known the resources of pisciculture at 

 home and abroad.
