The original compiler of the following work designed, in preparing it, to furnish a plain and concise system of PracTICAL SURVEYING.
That he did not fail of success, has been 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.
In the present edition, practical matter has been added by GEORGE GILLET, Esq., Surveyor General of the state of Connecticut, and in addition to all the tables of the best treatises extant, it contains the only table of Natural Tangents ever published in this country.
In the table of logarithms, and of logarithmic sines, &c., the decimals are carried to six figures, and a column of differences is added for the purpose of finding intermediate numbers. The use of these tables is so familiarly explained and illustrated by examples, that no other instruction upon this subject is necessary.
The articles on distributing estates, locating and surveying roads, and on levelling, cannot fail of being highly useful to the practical surveyor.
The work being now used extensively in schools and academies, it has been the chief object of the publishers to render it acceptable as a text book.
