Improvements in snow survey apparatus

A snow sampler combining the capacity and strength of the Mt. Rose sampler and the lightness of the Utah sampler was ordered by the U.S. Bureau of Agricultural Engineers. Dur-aluminum and steel samplers are evaluated as construction materials for strength, core removal, and ease of sampling. Most of the fundamental features of the Mt. Rose sampler were adopted. Design deviations from both sampler types are listed. The Mt. Rose spring balance is considered superior to the tubular or Utah balance. Designs of a new springless balance and a weighting staff of dur-aluminum for use with the spring balance are described and shown in pictures. Tabulations of types of balance are shown.
