An improvement in water wheels has been invented by J. Haseltine, of Goffstown, ?. H., lor which he has taken measures to secure a patent. The novelty of this invention consists in the form and manner of constructing the buckets, which are set at a tangent to the periphery of the shaft, so as to unite in a very convenient manner the direct and re-action water wheels, and thus obtain a longer continued action of the water upon the buckets. The improvement may be used to advantage in the vertical or horizontal wheels, and is said to operate well. It is well understood that the practical value of re-action scroll or combined wheels, must depend upon a series ot observations made upon their relative power—under similar circumstances—it is better to try these wheels than to undertake to calculate their power.
