• Figures in parentheses in the first column of elevations give approximately the lieights which the stages of the luko 

 during its outflow northeastward would have had at Lake Traverse if the land there had been low enough to permit the 

 lake to extend south to its former outlet. From these estimated elevations the nortliward ascents of these stages, also in 

 pareiithesea, are obtained, so as to be directly compared with the northward ascents of the beaches that were formed while 

 the lake outflowed southward, showing the clianges which were gradually taking place in the levels of the beaches of 

 Lake Agaaaiz during the whole time of its existence.
