MUSEUM BULLETIN NO. .2. 
temporary accounts of walrus hunting tell of the practice of 
driving the beasts from the waters or the floe ice up on to the 
low shore platforms and even into the woods, where they were 
shot at leisure. Possibly, then, some of the outer, barren 
beaches were already in existence when the walrus were slain 
in the woods close behind them, and the fossiliferous ridges are, 
therefore, older than we have assumed. Keeping this possi- 
bility in mind, we may say that the ridges in question date 
back at least to 1775. If, now, we assume that the growth of 
the beach plain, in the long run, has been steady, we may 
estimate that the age of the innermost beaches, which are as 
far behind the bone-bearing ridges as these are behind the 
modern beach, is probably not less than 300 years. 
Lines of levels were run from the shore across the plain to 
Lake Frye, to determine what difference in height, if any, exists 
among the beach ridges. The measurements follow: —

As the measurements show, the outer ridges, from the first to 
the twelfth, are on the average nearly three feet higher than the 
inner ridges, from the thirteenth to the twenty-eighth. This
