SPAULDING, Nathan Weston, inventor, born in the town of North Anson, Maine, 24 September, 1829. At the age of thirteen he began to learn the trade of a carpenter and builder under the tuition of his father, who was both a school-teacher and a practical mechanic. Afterward learning the trade of a millwright from an uncle and spending a year in a saw-factory, he had become at twenty the chief mechanic of his neighborhoed. Going to California in 1851, he went at once to the mines, but did not succeed, and was employed as superintendent of the construction of one of the first quartz-mills in the state. Its success led to the erection of a second on the same stream--Mokelumne river. In 1859 he opened a saw-manufactory in Sacramento, where he began to develop an inventive talent in the line of his business and devised the adjustable saw-tooth that has made him widely known. The demand for these teeth became so great that Mr. Spaulding, finding it difficult to supply them in sufficient quantities, was compelled to contrive other devices, and finally brought out the chisel-bit saw-tooth. He has also completed and published a scale for the measurement of logs, which has been adopted as the legal standard in California and other states, as also in several territories. It is known as the Spaulding log-scale. In 1861 he removed his factory to San Francisco, and he has since taken part in the industrial development of California. In 1881 he was appointed by President Garfield to be assistant United States treasurer at San Francisco, which office he held until 20 August, 1885. During that period he received and disbursed, or safely kept and transferred to his successor, more than $320,000,000 without loss. He has twice served as mayor of Oakland, where he resides, and has been selected by Leland Stanford as a trustee of the Leland Stanford, Jr., university.
