The Other Presidency


Book Description

In The Other Presidency, Patrick Spero resurrects an overlooked but essential part of Thomas Jefferson’s life. For nearly seventeen years, Jefferson served as President of the American Philosophical Society (APS), the nation’s first learned society and one dedicated to promoting new research in the young republic, especially in the sciences. He did so while also serving as Vice President and President of the United States. As Spero shows in this short but important work, Jefferson used his various positions to solidify the Society’s foundation and, in turn, shape the course of American science. Through a deep dive into APS Archives and Jefferson’s papers, Spero demonstrates how the Society became a thoroughly Jeffersonian institution—that is, the APS, the largest and most powerful scientific body in the nation, advanced an agenda that comported with Jefferson’s own priorities. While Jefferson juggled affairs of state, he also remained deeply involved in the Society. In fact, the two complemented each other. He helped draft the institution’s first collection development policy, making clear the items and material he thought most important for the nation’s posterity. He also used his international network to introduce European intellectuals to the Society, and he called on these same networks to help build the Society’s collection. Jefferson himself received direct support from the Society to conduct his own research, including funding for an expedition with James Madison, and as President of the United States, he would often call on the APS and its members for advice. In short, Spero shows that Jefferson was integral to the development of the APS—and, perhaps more unexpectedly, the APS and the scientific community it fostered were integral to Jefferson and his vision for the young United States. A resource for students, history buffs, and Jefferson aficionados, the book includes a chronology of Thomas Jefferson's contributions to the APS, with references to major events in Jefferson's life.

Principles of Sericulture


Book Description

Great progress has been made in the past decade in the field of sericulture research. Sericulture technique covering various aspects has also advanced greatly. Like agriculture, sericulture, as an industry, requires greater development in research and technology aimed at increased production. This text covers the complete range of subjects with current data relating to mulberry and silkworm. Particular emphasis has been laid on the basic aspects of stable crop of silkworm and various preventive measures against adverse factors. Topics covered include the sericulture industry and its future; mulberry cultivation; silkworm and its strains; silkworm eggs; morphology, physiology, ecology and genetics of the silkworm; diseases of silkworms; rearing of silkworms; cocoon; silkmoth and egg production; and utility of byproducts.




Silk Reeling and Testing Manual


Book Description

The continuous improvement and effective dissemination of the technology for silk reeling and testing are vital in meeting the ever increasing demand for quality raw silk throughout the world. This bulletin covers a wide range of techniques in the silk reeling industry. Details are given in each chapter on the handling of fresh cocoons, drying and storage of cocoons, cocoon boiling and reeling, raw silk-reeling and finishing, water quantity and quality, utilization of by-products and maintenance of the machinery used.
