A treatise upon the dendrometer, a new-invented instrument for the more certain and ready measurement of standing timber, by inspection only: for facilitating the practical operations of engineering, land-surveying, levelling, mineing, &c. And for performing mechanically the various cases of plane trigonometry, by a short and familiar process, without calculation.
