cases the worthless species can be killed. Then it is a 

 question of temperature, location and other things 

 which will determine its value with an equal area of 

 land. There is no fixed value for either land or water, 

 therefore the assertion quoted*is absurd and misleading. 

 The rearing of some fishes is attended with more care 

 than that of others ; for instance, the trout may be raised 

 in several different ways involving more or less care and 

 expense in the preparation of ponds, hatching appa- 

 ratus, etc., according to the system adopted, which is de- 

 pendent upon the amount of flow, extent of ponds and 

 the inclination of the owner and here let me say that in 

 the culture of fishes there are none which require as 

 much care as the trout. It is very particular about the 

 temperature in which it will live, anything above 75 de- 

 grees Fahrenheit, except in swiftly running water, be- 

 ing fatal ; therefore its culture is prohibited in all waters 

 where the bottom temperature rises above that figure. 

 Few fish eggs are easier to care for and hatch than those 

 of the trout, coming as they do from October to March, 

 as any running stream is then cold enough, even though 

 its summer temperature would be fatal to the young 

 fish, and the eggs will endure any degree of cold short 

 of freezing solid, even if surrounded by ice. As an off- 

 set to this, the young are delicate if kept in confined 

 quarters, as they are likely to be if hatched in great 

 numbers, and not turned into a stream or pond well sup- 

 plied with natural food, but kept to be fed by hand ; and 

 although 90 per cent, of the eggs may easily be hatched 

 and the greater portion of them may live during the 

 embryonic period in which they are subsisting upon the 

 yolk sac, which remains attached to the abdomen for a 

 period of forty to fifty days before they need food, they 

 are then apt, as before stated, to die very rapidly, and if
