THE STEW. 153 



it. In the hottest summers the development 

 of bright green scum, which is a confervoid 

 growth, will not then be encouraged. An 

 occasional raking over the bottom, followed 

 by a temporary raising of the inlet hatch so 

 as to admit more water, and a simultaneous 

 removal of the outlet hatch, to give it a 

 thorough sluice out, keeps the gravel clean and 

 bright. Every part of the stew being in 

 thorough repair, it is only necessary to empty 

 it throughout, and keep it empty for at least a 

 full fortnight, to render it fit to receive the 

 yearlings with every prospect of their thriving 

 and growing into large and well-proportioned 

 two-year-olds. 



Two seasons' experience of stocking arrange- 

 ments with the stew described have given an 

 insight into its strong and weak points which 

 may be of advantage to students of the 

 question, and hence I purpose giving the results 

 somewhat in detail. As a commencement, 

 1000 of Mr. Andrews' largest yearlings were 

 turned directly into the river in the month of 

 April, 1893, without the loss in transit on this 

 occasion of a single fish. A second and 

 similar batch of 1000 were to follow about a 

 week later, of which one half were destined for 

 the stew, and the balance to be at once con- 

 signed to the river.
