fill for yearlings, niusi he oinittod on account of their liigh price, 

 because for vearlin.us too large quantities are needed. On the 

 other hand, in tlie front rank and especiall}' to be recommended 

 for feeding ycai'lings is fi'csh bsb. I'bis is ])r(']iared just as 

 already described for fry feeding. Altho fish too commonly 

 reaches a pretty high price, especially in soiitlicrn Germany, 

 where the transportation of ^ fresh sea-fish during the warm sea- 

 son becomes much more difficult, and where consequently only 

 the cheaper fresh-water fish are available, there is nevertheless 

 no other better food and this is therefore to be placed in the front 

 rank, in spite of increased price. 



As a substitute for fresh fish, frog flesh may serve. AMien it is 

 possible to get frogs in quantities, they are killed, boiled, and, 

 after the removal of the large bones, ground fine, and fed out just 

 like fish. In the same way it may be recommended to collect living 

 land snails of all sorts. If these have shells, the shells must not 

 get into the food, because splinters of shell generally are as sharp 

 as glass, and might injure the intestines of the fish. To remove 

 the shells the snails are thrown into boiling water, where they 

 immediately die, and may then be easily pulled out of the shell. 



If it is not possible to have fresh flesh of frogs or snails 

 always ready in sufficient quantity, as unfortunately will often 

 be the case, it is necessary to have recourse either to slaughter- 

 house offal or to dry foods. The slaughter-house offal, that is, 

 the cheap meat not used for human food, such, for instance, as 

 comes off from the plucks and from the hide, is often em- 

 ployed as food for yearlings, and in this way : it is first cooked 

 and then ground fine with a machine and thrown directly to 

 the fish. This food has not, however, been always approved 

 in the rearing of yearlings. It is asserted that from its use 

 serious intestinal diseases appear among the 3'oung fish and 

 it seems that this offal is too indigestible for them. It happens 

 tliat much slaughter-house waste sometimes comes to be fed 

 not entirely fresh, and then severe diarrhea and even a great 

 mortality to the young fish result. The same which has been 

 said of offal applies also to horse meat. This also, like the 

 oft'al, is, on account of indigostil)ility, not to be recom- 

 mended as food for yearlings. Especially is further warning- 

 necessary to avoid smoked or salted horse flesh which the young
