It is noted by Professor Matsubara that when ryukins with a two-rudder caudal fin are mated 

 the progeny have long tails, but when fish with a one-rudder tail are brought together the tail in the 

 offspring is short. 



Sometimes, through the unfortunate choice of brood fish that appear to be entirely satisfactory, 

 a large percentage of a lot of fish may have unsplit tails, whereas the culturist had every reason to 

 expect split tails ; this is serious from a business standpoint, as the fish with unsplit tail bring very 

 much less money than the others. 



Professor Mitsukuri cites it as an interesting fact that when the ryukin and the ranchu are 

 crossed to make the oranda shishigashira both dorsal and caudal fins remain long, while in the cross- 

 ing of the oianda with the ranchu to produce the shukin the dorsal fin is lost and the caudal remains 

 long. 



In all broods of the varieties lacking the dorsal fin, a certain percentage of the young show 

 vestiges of that fin sometimes a miniature fin, sometimes a few rays, sometimes a number of 

 rounded protuberances, sometimes a single spine, all suggesting the comparatively recent period at 

 which the fin was lost. 



Transportation of Goldfish 



The commoner varieties of goldfish bear transp)rtation well if proper precautions are taken, whether 

 the vehicle be steamship, express train, wagon or man, and whether the distance be long or short. 

 Whenever there is serious loss in sending the hardier varieties from place to place, the responsibility 

 usually rests on the shipper or attendant. Some of the more highly cultivated varieties, however,
