That he did not fail of success, has been sufficiently proved, by the high estimation in which this treatise has been, and is, at the present time, held by surveyors, and by the continued and increasing demand for it, from the public. In the present edition, the publishers have used every exertion to render it still more worthy of patronage. The valuable articles furnished to the fifth edition of the work, last published, by GEORGE GILLET, Esq., Surveyor General of the state of Connecticut, are retained in this. They will be found to contain a system of useful instructions for the practical surveyor, which cannot be elsewhere found. Additional matter has likewise been inserted in the present edition. These additions, when entirely independent of any thing previously contained in the book, or when substituted as an improvement for something omitted or altered, are inclosed in brackets, or are inserted in the form of a note at the foot of the page.
