262 Fortieth Annual Meeting 



point at which to win against the current, swim into it. 

 The wheel itself, like a big windmill, is turned round and 

 round by the current of the river. You see two of its arms 

 like the wings of a windmill. When one of these is directed 

 perpendicularly downward the salmon swim into it. Each 

 wing is a big scoop opening down stream and constructed of 

 chicken wire on a frame, and as the wheel turns around, 

 the scoop directed downward into which the fish has swum 

 is carried forward and lifted out of the water as the current 

 grips the next in order. Of course the fish are then rolled 

 toward the hub of the wheel, where a slide takes them out 

 into the fish-box. 



[Slide of model of large cub shark being prepared for 

 exhibition in the museum's laboratories.] This is a model 

 of a shark captured last February at Key West. It measured 

 about nine feet. Casts of it were taken at Key West by a 

 scientific expedition undertaken in the interests of the 

 museum by two of its members, and from the casts, after 

 they had been brought to the museum, a model was prepared 

 which you see here in process of preparation. 



[Colored slide of a shark.] There is the shark on the 

 beach at Key West. It is the cub shark, called blue shark 

 at Key West. You seldom see it at the surface, but it is 

 quite common in Key West harbor, and the small boys do 

 not seem to mind it at all; they go in swimming just the 

 same. I presume it feeds a good deal on carrion. We 

 found a tin can in the stomach of one of them. 



Although the blue shark is not dreaded, the tiger shark 

 is very much dreaded in that locality, and I have also heard 

 from the captain of a Ward liner who trades in those 

 regions and occasionally brings us rare fish, that throughout 

 the southern regions the tiger shark is very much dreaded. 

 He tells of a case where hogs were being loaded on steamers 

 by means of rafts, and these sharks tried to knock the men 

 on the rafts overboard by bumping into the rafts. 



[Slide of a swordfish model.] This is a swordfish being 

 prepared at present in the museum.
