Excerpt from Micro-Organisms of Maple Sap The experimental work upon which a report is submitted in these pages was undertaken in an effort to determine as far as might be possible the answers to the following questions: What is the cause of the deterioration of maple sap? Is it due to changes in composition occurring within the tissues of the tree as a result of the resumption of protoplasmic activities and vegetative vigor? Is it due to the action of micro-organ isms in the sap after it leaves the vascular bundles of the trunk?
