K. C. BERGER AND R. J. MUCKENHIRN SOIL profiles mounted with lacquer or plastic by methods developed by Lyford (2) and Harper (i) on cloth or wood backing are more effective and convenient for display and study purposes than soil monoliths. However, profiles an inch or more in thickness are necessary to show the blocky structure of the B horizons of fine-textured soils of the GrayBrown Podzolic Group. For such mounts, a more thorough cementing of the particles and aggregates is necessary than is usually obtained by the Lyford method in which cellulose nitrate is applied to the back only. Consequently, the authors applied plastic solutions to both the face and back of the profiles. This step led to experimentation with the use of plastics for the restoration and retention of colors like those of moist soil. McClure and Converse (3) had used lacquer on soil monoliths for the same purpose. Cellulose nitrate and some other plastics produced a yellowish tinge or a glossy coating. However, vinylite resin in ketone solutions, being colorless and capable of rilling the soil pores as does water, restored the natural color of the moist soil. Upon drying, it preserved this color, cemented the soil particles and aggregates firmly in place, and, when properly applied, did not form a glossy coating. The details of the methods developed to obtain and mount the soil profiles with vinylite resin are presented in this paper.
