Microtome thin sections provide valuable information with which to characterize peat samples. New methods of preparing peat microtome sections have been developed that produce uniform, durable samples in less time. Dehydration and impregnation cages are formed with a punch and die, and impregnated samples are mounted on embedding rings and molds. These modified microtoming procedures, used in conjunction with critical-point-drying and polishing techniques, have led to advances in scanning electron microscopic and reflected-light studies of peats. 8 refs., 21 figs.
