SE5JOR ALCATRAZ AND THE CATFISH 



HE boy is not the only creature which has dubi-

 turned forward and joined together in one broad web, and 

 his wings were thick and clumsy, and underneath his long 

 bill there was a big red sack that he could fill with fishes,

But one morning as he was walking out on the sandflat 

 of the Astillero at Mazatlan, Mexico, where he lived, he
