sites that have a tragic history. Beavers, with 

 Omar, might say, 



" When you and I behind the veil are past, 

 Oh but the long long while the world shall last." 



The next summer, 1893, the Moraine site was 

 resettled. During the first season the colonists 

 put in their time repairing dams and were con- 

 tent to live in holes. In autumn they gathered 

 no harvest, and no trace of them could be found 

 after the snow; so it is likely that they had 

 returned to winter in the colony whence they 

 had come. But early in the next spring there 

 were reinforced numbers of them at work estab- 

 lishing a permanent settlement. Three dams 

 were repaired, and in the autumn many of the 

 golden leaves that fell found lodgment in the 

 fresh plaster of two new houses. 



Most beaver dams are built on the install- 

 ment plan, are the result of growth. As the 

 pond fills with sediment, and the water becomes 

 shallower, the dam is built higher and, where 

 conditions require it, longer; or, as is often the 

 case, it may be raised and lengthened for the 

 purpose of raising or backing water to the trees
