any, owing to the introduction of tliis iish. One dillieiilty has liren experienced, 

 and that is that the natives and (1iine.se catch them in eonsideiable quantities 

 to cut and for bait. 



As a ri'sult of 1113' experience in eari'uiif;- live fi.'-Ji ;;Ti'at distances, I 

 have found that there are three important tilings which must not be 

 lost si^^hL of. first, ch'anliness. All ea.ns in which the fisli are trans- 

 ported must be eleaneil tlinroiif^'lily at least every third day with hot 

 \\'ater; lliis pi'(.'\ciits the L;•|■(l^^■tlL of fungus. Tln' water in the cans 

 must always be pure and the e.xereiuent and uneaten food must be 

 siphoned out each day. The fish must iiever be touched with the hands. 

 Second, lempcrature. Alime all else a sudden change in the tempera- 

 ture of the water must be a\(iide(l; it must ne\ei- lie changed all at 

 onee^ but the i'resli water must gradually lie laixed with that in which 

 the fish already are. It shonld take at least se-vcjal hours to lower the 

 temperature one or even one-half degree. Third, vigUancc. Success 

 in this Mork is attained only at the cost of eternal vigilance, >\MTien 

 the fish are suffering from anv' cause whatsoe\e)', they come to the top 

 of the can continually and only by constant care and watching can 

 the jDroper remedy be Icamecl.
