RECOMMENDATIONS.

[ocr errors]

HAVING perused, with some attention, the following Treatise on Surveying, in Manuscript, it appears to me to be estimable for its simplicity and perspicuity; and, by excluding all matter but remotely connected with the main subject, and reducing the Tables of Logarithms, of Logarithmic Sines, Tangents, and Secants, and of Difference of Latitude and Departure, without impairing their use, in their application to most cases which occur in common Surveying, and supplying any possible defect by a Table of Natural Sines, to comprise, in the limits of a pocket volume, whatever is most essential and most useful in the Art, including the important modern improvement of RecTANGULAR SURVEYING; and on the whole, particularly from the size of the volume, to be well adapted to general use.
