We invite you to visit... In 1880 the site that was to become Glenwood City was a tranquil glen (valley) in the midst of huge forests. By 1885-1890 with the coming of the railroad and the lumber mills, Glenwood was the major trading center of the area with a population of 2000.
English walnut trees can be tapped successfully, especially when subjected to a freezing winter and spring. Paper birch (Betula papyrifera) The paper birch has a lower sugar content than sugar maple (less than 1%), but is the sweetest of the birch trees.
As tree sap flows through the sapwood part of the tree, it produces carbon dioxide. This creates positive pressure and if there are any wounds or holes in the sapwood, the sap will ooze out. This is how harvesting saps from trees is achieved; cut or create a hole.
