54 WATCHED BY WILD ANIMALS 



beaver house each young beaver started in turn 

 as though to climb to the top, poor Mother 

 Robin became almost hysterical. At last, de- 

 spite all her fears, her entire brood was brought 

 safely off. 



During the summer, a majority of the Broken 

 Tree beavers abandoned the colony and moved 

 to other scenes. A number built a half-mile 

 down stream, while the others, with one excep- 

 tion, travelled to an abandoned beaver colony 

 on the first stream to the north. Overland this 

 place was only half a mile from the Broken Tree, 

 but by water route, down stream to the forks 

 then up the other stream to the colony, the dis- 

 tance was three miles. This was an excellent 

 place to live, and with but little repair an old 

 abandoned dam was made better than a new 

 one. All summer a lone beaver of this colony 

 rambled about. Once he returned to the Broken 

 Tree colony. Finally, he cast his lot with the 

 long-established colony several miles down 

 stream. 



Late this summer a huge landslide occurred 

 on the stream above the Broken Tree pond. 

 The slide material blocked the channel and 

 formed a large, deep pond. From this dam of 

 debris and the torn slope from which it slipped 

 came such quantities of sediment that it ap- 

 peared as though the pond might be filled.
