ten to twelve days old. We use the blood of veal or beef mixed 

 with sweet milk or cream, and water enough to make it as thin as 

 water itself which is done by taking a small quantity of the blood 

 into a dish with about the same quantity of cream or twice the 

 quantity of sweet milk, and then stirring it thoroughly ; after it has 

 become welt mixed, we then commence adding water and continue 

 to add the same until the whole has the appearance of roily water, 

 when it is ready for use. We then pour into the trough at the up- 

 per end so that the current will carry it down the entire length and 

 give the fry ample time and opportunity to partake of the food. 



The first positive indications we have that they are feeding is the 

 unusual excitement which is shown by their continually darting hith- 

 er and thither through the roily substance. In a short time you can 

 discern in them a marked difference in the color of the body, which 

 loses transparency and becomes dark. After the fry have been feed- 

 ing a few days we dispense with the cream or milk and use only 

 water for thining the blood. When two months old they will take 

 liver ground fine using water in the same manner as with the blood. 

 When a few months old they take the ground liver prepared in the 

 same way you prepare it for young trout. Care should be taken not 

 to feed any food in lumps as they seem to choke easily, in fact the 

 only fish we have lost of those of the hatch of 1877 in six months 

 past, three in number, have choked to death with careless feeding. 

 They become nearly as ravenous feeders as the trout, rising and 

 taking their food near the surface and also picking it from the bot- 

 tom which is covered with fine sand kept clean and free from de- 

 composed food. 



I have no doubt those I have been feeding the past fourteen months 

 would take the hook as readily as the trout of the same age.
