4 TROUT CULTURE. 



aqueous vapour. A pair of indiarubber gloves lined 

 with wool will be found a most comfortable adjunct 

 to the furniture of the fish-breeding establishment. 



For the supply of waterproof articles we have long 

 employed Mr. George Cording, of 125, Regent Street, 

 231, Strand, and i, Albemarle Street, and can speak 

 very highly of his productions. 



The first matter of a special nature, which it behoves 

 us to consider, is of necessity the ^ater in which we 

 propose to grow trout. The phrase *' to grow trout," 

 may seem an odd expression ; but it is, nevertheless, 

 perfectly correct. For, just as in good soil, well 

 manured, and with favourable conditions of rainfall, 

 etc., it is easy to grow good seed and secure a heavy 

 crop, so in good water, with good eggs, and a liberal 

 supply of natural or artificial food, it is easy to rear or 

 grow trout to an extent, both of number and size, 

 which will fairly astonish those who are unacquainted 

 with the mysteries of trout-life. 



To hatch the eggs we only require pure water, of 

 which the hatching-house should have an ample 

 supply. Whether this be derived from stream or 

 spring is of small consequence, so long as the tem- 

 perature be not liable to sudden changes, as these are 

 likely to interfere with the gradual and even develop- 

 ment of the embryo. On the whole, therefore, we are 

 inclined to prefer spring water for our hatching opera- 

 tions. For rearing the fry when removed from the 

 hatching boxes, we also require pure water ; free from 

 pollutions. But it should be well stocked with insects 

 and animalculae, as these afford a constant supply of 

 natural food for the young fishes. It may be stream 

 or spring water so long as these conditions are fulfilled,
