Excerpt from Short Papers on Geologic Subjects: Present State of Knowledge Regarding the Pre-Cambrian Crystallines of Illinois; Factors Affecting Measurement of Permeability of Unconsolidated Glacial Material; Facies Analyses of the Niagaran Rocks
A piece of metric cross-section paper placed between two pieces of lucite served to delineate a given area. Small portions of a sieved sample were placed on the ruled piece of lucite and examined under a microscope. Grains within a given area were counted and an estimate was made of the percentage of each of the three shapes. A less rapid but more accurate method would be to make counts from photomicrographs.
