I am much pleased with the Treatise on Surveying, compiled by John Gummere, and hope to see it speedily introduced into general use. With those who appreciate its merits, I apprehend it will supersede every other tract on the subject with which I am acquainted. ENOCH LEWIS. We have no hesitation in giving it as our judgment, that Gummere's Treatise on Surveying is the best publication on the subject with which we are acquainted, and we, accordingly, take great pleasure in recommending it to the public patronage. Prof. of Math. and Nat. Phil. in the Univer. of Pennsylvania. The Treatise on Surveying by John Gummere, is, in our estimation, a very judicious performance. Several things are omitted which only serve to encumber other works on this subject, and a variety of new rules and illustrations are introduced, particularly under the heads of laying out, measuring, and dividing land, which, in connec tion with its general arrangement, render this Treatise on Surveying, in our opinion, decidedly preferable to any other which has met the public eye.

Having carefully examined a Treatise on Surveying, by John Gummere, I feel myself perfectly justifiable in pronouncing it to be the best practical work on the subject extant.
