TROUT CULTURE 



HOT AIR ENGINE. 



Where we can get satisfactory pumping power, by 

 hand, horse or steam, and a cistern of a sufficient size 

 to hold thirty hours' supply for the whole hatching 

 operations, we may be quite contented so far as water 

 supply is concerned. 



Lead piping may be used with perfect safety in fish 

 culture, and junctions may also be made with india- 

 rubber piping, a great convenience in altering or 

 extemporizing apparatus ; but india-rubber of the best 

 quality only should be employed, as the chalky stuff 

 sold by some firms will only lead to leaks and losses. 

 Black or red rubber should be selected, and from a 

 firm of standing.
