Hemp Hurds as Paper-Making Material is a comprehensive scientific report authored by Lyster H. Dewey and Jason L. Merrill, originally published by the United States Department of Agriculture in 1916. This seminal work investigates the potential of hemp hurds-the woody inner portions of the hemp stalk-as a viable raw material for the manufacture of paper. Drawing on a series of laboratory experiments and industrial trials, the authors meticulously compare the properties of hemp hurds with traditional paper-making fibers such as wood pulp, rag, and straw. The book delves into the chemical composition of hemp hurds, detailing their cellulose content, fiber length, and the processes required to convert them into pulp suitable for paper production. It discusses the mechanical and chemical pulping methods, the yields obtained, and the quality of paper produced from hemp hurds, including its strength, color, and texture. The authors also address the economic and practical considerations of using hemp as a paper source, such as the availability of raw material, harvesting techniques, and the adaptability of existing paper mills to process hemp hurds. Rich with data, tables, and comparative analyses, Hemp Hurds as Paper-Making Material provides valuable insights into the early 20th-century search for alternative paper-making resources. It highlights the environmental and industrial significance of hemp, foreshadowing modern interest in sustainable and renewable materials. This book is an essential reference for historians, environmentalists, and anyone interested in the history of papermaking, agricultural innovation, and the versatile uses of the hemp plant.
