This book was originally published prior to 1923, and represents a reproduction of an important historical work, maintaining the same format as the original work. While some publishers have opted to apply OCR (optical character recognition) technology to the process, we believe this leads to sub-optimal results (frequent typographical errors, strange characters and confusing formatting) and does not adequately preserve the historical character of the original artifact. We believe this work is culturally important in its original archival form. While we strive to adequately clean and digitally enhance the original work, there are occasionally instances where imperfections such as blurred or missing pages, poor pictures or errant marks may have been introduced due to either the quality of the original work or the scanning process itself. Despite these occasional imperfections, we have brought it back into print as part of our ongoing global book preservation commitment, providing customers with access to the best possible historical reprints. We appreciate your understanding of these occasional imperfections, and sincerely hope you enjoy seeing the book in a format as close as possible to that intended by the original publisher.

Thomas Ewbank was born of humble parents in Durham, England.
He attended school until he was thirteen years old, and then was apprenticed to the trade of sheet-metal working.
He served an indenture of seven years as a tin- and coppersmith, shaped- iron and wire worker, plumber, brass founder, and shot caster. In 1812 he went to London and for seven years more was employed as a tinsmith. With the money he could save he bought books and utilized his leisure in study and reading. He was gradually led to the belief that monarchical institutions limit one’s capabilities, and as a result of his conviction emigrated to the United States in 1819 and settled in New York. Shortly after his arrival he began the manufacture of copper, lead, and tin tubing, and for sixteen years continued in this business with marked success. He secured also his first patents, two in 1823 and one in 1832, for improved methods of tinning lead, both sheet and pipe, and two in 1830 and one in 1831 for improved steam safety valves. By 1836, since his business had yielded him a modest competency, he sold it to devote his whole time to study, travel, and writing. This was the result of an exhaustive study of devices used for raising water, was profusely illustrated, and was one of the standard works on the subject. The sixteenth edition was published in 1870. From 1845 to 1848 he traveled in South America, studying both the natural phenomena and the industrial arts. Shortly after his return he was appointed commissioner of patents by President Taylor, which office he assumed May 4, 1849, and directed until 1852. His long study and interest in invention, particularly its historical aspects, is reflected in his annual reports which contain enthusiastic and delightful essays upon his favorite theme, and were prepared primarily to arouse popular interest in the industrial application of physical and chemical sciences. Ewbank did not entirely escape Congressional criticism while commissioner. He was accused of discriminating against some would-be patentees, a charge which was never proved, and for publishing his essays in the Patent Office reports. Senator Foote of Mississippi was especially opposed to the essays, which he described as being "more poetically grand, more brilliant, more fanciful, more Byronic than any of the most fanciful poems that Lord Byron ever produced. ” On the other hand, during his administration Ewbank succeeded in doubling the examining force and laid the foundation for the present rules of practise which greatly expedite the handling of claims. Upon his return to private life he again took up his writing in New York. The World a Workshop; or, the Physical Relation of Man to the Earth appeared in 1855 ; Life in Brasil, one of his most entertaining books, in 1856; Thoughts on Matter and Force in 1858; and Reminiscences of the Patent Office in 1859. Interspersed with these were many pamphlets on as many different subjects, such as “Inorganic Forces Ordained to Supersede Human Slavery, ” an essay read in 1860 before the American Ethnological Society of which he was one of the founders; and North American Rock-Writing, published in 1866. As a member of the commission to examine into the strength of the marble offered for the extension of the Capitol at Washington, Ewbank rendered valuable services by the determination of a method to increase the pressure resistance of building stones.
