282 Lake Michigan

While the water is thus wasting away the west shore, it as constantly causes an accumulation of sand on the east shore; which being thrown up by the waves during heavy seas, soon becomes dry and is carried inland by the action of the winds. This loose sand forms hills varying in height from ten to one hundred and fifty feet, whose forms are constantly changing by the moving of the sand by the winds: and it is remarked that the sand is gradually [app]enchroasing upon the land and may, unless some sufficient barrier is opposed to its progress, eventually spread over a considerable portion of the state of Michigan*

Lake Michigan may therefore be considered as adopting the spirit of the age and moving to the west! Whether the encroachment on Wisconsin is balanced by the accumulation in Michigan or whether the lake is increasing or diminishing in width cannot easily be determined. As the ground rises immediately west of the shore and is based upon limestone rock lying at a considerable elevation above the water it is evident that the progress of the lake in that direction will soon be stopped.
