84 FISH CULTUEE. 



have been turning on their sides in an apparently 

 dying condition, instantly dive to the bottom and 

 assume their natural position. By this means large- 

 ish fish may be conveyed a considerable distance. 1 

 Should one or two, however, really die, they should 

 always be speedily removed ; this should not be 

 done by the hand, but by means of a small net : 

 indeed, the hand should not be used in contact with 

 these live fish oftener than is positively unavoidable. 

 An ingenious little apparatus has been made where 

 only a small quantity — such as a bait-kettleful of 

 baits, for example — is required. This is a gutta 

 percha tube, bent at the lower end and pierced with 

 small holes. Upon the upper end is fixed one of 

 those hollow india-rubber balls that children play 

 with ; at the top of the ball is a small hole, on 

 this the forefinger is placed. The tube is passed 

 to the bottom of the bait-kettle. The india-rubber 

 ball is compressed suddenly, and an admirable little 

 force-pump, supplying plenty of air, is the result. 



it carry a small leaden pipe across the bottom of the cask. This 

 pipe should be drilled full of small holes, and at every stroke of 

 the pump a shower of air bubbles rushes through the water. The 

 top should not be thoroughly open, but a large round hole should 

 be cut for air. 



1 Large grayling have been conveyed a distance of 250 miles 

 in it with little damage or loss.
