During periods of transit and storage, previous to its ultimate manufacture, green timber containing a high percentage of sapwood' often suffers considerable damage. This is particularly true during the late spring and summer months when deterioration brought about mainly through a discoloration of the sapwood, known as sap-stain, sometimes necessitates degrading on a large scale. This staining of timber has occasioned severe losses in Europe as well as in the United States, and many expensive investigations have been made to determine the nature of the stain and to discover a satisfactory remedy. 1 The writer wishes to acknowledge his indebtedness to Mr. C.
