Excerpt from Relation of Light Chipping to the Commercial Yield of Naval Stores
As the chipped surface is gradually extended up the tree a point is reached, usually at the beginning or middle of the third year of operation, where the use of the hack is no longer practicable. From this point on, the puller is substituted. This serves the same pur pose as the hack, but its long handle enables the workman to reach higher.

Paperback. Zustand: New. Print on Demand. This book is a comprehensive analysis of a series of field experiments conducted in the early 20th century by the author, a US Forest Service employee, on the techniques and environmental impacts of turpentine extraction methods. At the time, the turpentine industry was booming, but also rapidly depleting the timber supply and causing widespread tree death. In response, the author conducted a four-year study on alternative methods of extracting turpentine, focusing specifically on the depth and width of cuts made in the trees' bark. The results of this study had a transformative impact on the industry, supporting the author's hypothesis that shallower and narrower cuts were not only more sustainable but also resulted in increased turpentine yields. This work laid the foundation for the preservation of the turpentine industry and the conservation of the timber supply, with the author's methods still widely used today. This book is a reproduction of an important historical work, digitally reconstructed using state-of-the-art technology to preserve the original format.
