The author, Dr. Ralph Ruskin Huestis, during his summer vacations, has served, with several breaks in continuity, as a ranger naturalist in Crater Lake National park since the middle thirties. He was born in Bridgewater, Nova Scotia, on January 14, 1892, and received his BSA degree from McGill University in 1914. From 1914 to 1919 he served with the Canadian Expeditionary Forces. Entering the University of California for graduate work, he received a Master of Science degree in 1920, and completed his work for the degree of Doctor of Philosophy in 1924. At the same time, he served as assistant biologist at Scripps Institute in California. Since 1924, he has been a member of the faculty of the University of Oregon, and is now a professor of biology at that Institution. Professor Huestis has been celebrated for his ability to make natural history interesting, for interpreting science and scientific subjects in a language that the layman appreciates. This special bulletin is a reflection of that ability as well as a fine contribution to our knowledge of one of the most fascinating small mammals of the Park fauna.
