two boles through each end for the cords by whicli they are fastened 

 to the foot. Figure 69 (1 and la) show the upper and lower surfaces 

 of a broader and heavier pair of ice creepers from the Diomede islands. 

 They are turned up at the ends to retain them in place on the foot, and 

 have four rows of pyramidal points along the lower surface. 



Figure 69 (2 and 4), from St Michael and St Lawrence island, respec-

 by which they are fostened on. 



Other creepers of similar style were obtained Irom Plover bay on 

 the Siberian shore. 



BOATS 



The Eskimo of the Alaskan coast, the islands of Bering strait, and

 use by Greenlanders. Among the people from the head of Xorton
