"The hardwood flooring industry is losing a new and vigorous market by default. The mobile-home industry produced over 250 million square feet of single-family housing space last year, and very little of this floor space was covered with hardwood flooring. A preliminary glance at this situation seems to uncover an industry that offers many opportunities for hardwood flooring manufacturers. Why then is so little hardwood flooring being used? To learn more about this growing industry and to discover some of the factors that now limit the use of hardwood flooring, a series of discussions were held with executives in the industry. S3

S2Pills of paraformaldehyde (trioxymethylene) are commonly used in tapholes in sugar maple trees (Acer saccharum Marsh.) to increase the yield of sap collected for making syrup and sugar (2, 4, 5, 8). The explanation offered for this increase in sap yield is that microorganisms in the tapholes (7) cause premature decline and stoppage of the sap flow (1, 6), but that paraformaldehyde increases sap yield by inhibiting their growth (2). But what happens to the tree? To determine the effects of paraformaldehyde on the tissues surrounding tapholes, and on the microorganisms in those tissues, sugar maple trees were dissected and studied. This paper is a report on that study.S3.
