Tn the upper loch the average depth is over 22 fathoms ; in some places 

 it reaches 75 fathoms. The average depth of the lower loch is greater, 

 and in some parts the depth is over 80 fathoms. As a rule the water 

 rapidly deepens from the shore, and the localities where there are 

 stretches of sandy beach are few in number, that is to say, places 

 suited for the life and growth of young plaice on the completion of their 

 transformation and the commencement of their bottom habit. 



The larvae from the hatchery were transported by rail during the 

 uight, usually in large glass carboys, the water of which had been cooled 

 to a suitable extent, ascertained by a number of experiments, and the fry 

 were placed in the water in the upper loch early next morning, at a depth 

 where a suitable salinity and temperature existed. The earlier consignments 

 were carried in receptacles cooled by ice during transit, but the other 

 method was found to be most satisfactory. All the fry were placed in 

 the waters of the upper loch, and usually in the upper parts of it, and 

 fry were put in in each year from 1896 to 1902, as detailed in the 

 following Table : —
