A correspondent—C. A. White, of Burlington, Iowa,—informs us that the following method of building cisterns in moist ground will effectually prevent water soaking through them from the outside and inside also :— " The bottom of the cistern is spread with hydraulic cement in the usual manner, then laid over with brick, upon which the wall is commenced about an inch, or an inch and a half from the earth all around. When the wall is about four courses high, the interstices between the wall and the earth are filled with grout, or the ordinary cement, made very thin, and poured in ; then build up the wall, and fill in with grout as before. When the cistern is plastered inside, the wall is completely encased with a coat of cement, that prevents the passage of water both wajs." Two schooners have already cleared from Detroit, Mich., this season, direct for liver-pool, and seven more are to sail on like voyages during the present month. Their cargoes are principally staves and other small hardwood timber. Patent Claims Issued from the United States Patent Office FOR THE WEEK ENDING MAY 11, 1858.

DRESSING AND SIZING WARPS—William Bradley, of Manchester, Va. : I am aware that drying cylinders have been used heretofore in dressing frames, therefore I make no claim to them. Neither do I claim as new the circular brushes. I am also well aware that reeds and harness have been used heretofore in dressing machines, consequently I make no claim to them as such. But I claim the combination of the section sleys or reeds, together with the warp sleys or reeda, and the harness for taking the lease or cross shed before the warp is sized in every alternate thread or threads, so as to allow the lease rods to pass with the warp to the yarn beamj and thus dispense with the use of eombs, ravels, or guides, after the warp has passed through the size, substantially as described. HARVESTERS—C. B. Brown, of Alton, 111. : I am aware that endless aprons have been applied to harvesters, and arranged in various ways, for the purpose of discharging the cut grain therefrom. But I am not aware that an apron has been arranged as shown, and used in connection with guides, so as to discharge the cut hemp at a distance from the standing hemp, in order to torn an unobstructed track for the team. I do not claim, therefore, an endless apron separately considered, or independent of the arrangement shown. But I claim placing the endless apron, F, in an oblique position with the sickle, E, so as to operate as and for the purpose set forth. I also claim the endless apron, F, in combination with the guide rods, IK, and sickle, E, when the several parts are placed relatively with each other, as shown, so as to operate as and for the purpose specified.

We also claim the two wedge rollers, or wedges, P' and P", to keep the board clear of the saw. while cutting in either direction, as described. We also claim the combination of pinions, i, and pins, o, entering into recessQS of plates, b, the ratchet wheels, g, the ratchets, a, the adjustable segments, J, the wheels, G', the screws, G, and the rods, K, with their clutches, z and v, for the purpose of setting the log to the saw, and stopping the setting when the log frame advances too close to the saw. And we also claim the notched plate, t, in combination with the latch, g, lever w, and link, 1, for the purpose of operating the belt shifter, 1, withont turning the lever, D, substantially as set forth. SEED PLANTERS—B. Kuhns, of Dayton. Ohio, and M. J. Haines, of Delaware City, Del. Patented Sep t. 30, 1856 : We make no claim to the pocketed wheel nf itself, nor do we claim the adjustable seed discharge apertures. We also disclaim the grooved roller in Fig. 27, and described on page 104 of Low's Elements of Practical Agriculture. But we claim the pocketed roller, as described, running close to the bottom of the cell, in combination with the adjustable aperture in said cell bottom, when the relation between the width ot the pocket and maximum size of the aperture is such that the pocket will always embrace the apertures, and for the purposes described. SEEDING MACHINES—C. W. Cahoon (assignor to J. B. Cahoon and D. H. Furbish), of Portland, Me. Patented Sept. 1,1857:1 do not claim the slide, b, nor the rock shaft, c, with teeth, d, attached, for stirring or agitating the seed within the hopper, separately ; neither do I claim distributing or sewing seed broadcast by means of centrifugal force effected by the rotation of wheels or cylinders, irrespective of the construction and arrangement shown. But I claim, first, The employment of a tubular chamber or discharger, rotating rapidly in a horizontal po sition, BO that its outer edge or periphery will be in a plane vertical or nearly vertical to the horizon, and thereby communicating a centrifugal motion to the grain, seed, &c, away from the center of a circle whose plane is thus vertical or nearly vertical to the horizon. Second, The employment of a funnel-shaped discharging chamber for the purpose, and rotating in the position above described, having spiral flanches or their equivalents inserted therein, and operating to arrest the too direct flow of the grain or seed, &c. through the discharger, and retaining it therein until the necessary centrifugolforce is communicated to it before it leaves the discharger, as above described. Third, The combination and use of the above described and above elaimed tubular or funnel-shaped discharging chamber, rotating in the position above de-Bcribed with the di3k, H, placed aud operating in the manner above described. Fourth, The combination and use of the above described and above claimed tubular or funnel-shaped discharging chamber, rotating in the position above described whether with or without the use of the disk, H, with a hopper constructed of any proper material, and fitted with the slide b, and rock shaft c, with teeth d, attached, or their equivalents, and operating substantially in the manner above described to feed the grain, seed, &c., into the discharging chamber. MACHINERY FOR SEPARATING FLOUR FROM BRAN—Issa-char Frost and James Monroe, ot Albion, Mich., assignors to Henry A, Burr, L D. Condit, Alex. Swift, D. Barnum, and Joan M. Carr, of New York City. Patented Feb. 27, 1849—Re-issued March 13,1855—Again re-iasued May 11,1858 : We do not claim as our invention the placing of the bolt in a vertical position as this was known before our said invention, but under a combination of parts resulting in a mode of operation essentially different from our said invention. Nor do we claim any of the separate parts, or sub-combinations other than as after specified. What we do claim is, the combination of the following essential features or their equivalents, viz. :— Firat, The vertical or nearly vertical position of the bolt. Second, A surrounding case forming a chamber or chambers around the bolt, substantially as and for the purpose specified, and provided with suitable means for the delivery of the flour as specified. Third, A rotating distributing head at or near the upper end of the bolt, substantially as described. Fourth, Rotating beaters or fans within the bolt, substantially as and for the purpose specified. We also claim, in combination with the first, second, and fourth features of the combination first claimed, the closed up top of the bolt, except an aperture or apertures for the admission of the material and air, substantially as and for the purpose specified. We also claim, in combination with the first, second, and fourth features of the combination first claimed, the closed up bottom of the bolt proper, except an aperture or apertures for the discharge of the bran, substantially as and for the purpose specified ; whether the said bottom be, or be not specially provided with an aperture or apertures, for the admission of air as specified. We also claim, in combination with the third combination claimed, or the equivalent of the features thereof, the employment of rotating arm3, or swings moving in closeproximity with tlie inner surface of the closed up bottom, substantially as and for the purpose specified. We claim the combination of all the features specified as essential features, substantially as described, or any equivalents for any or all of the said features. DEBISNB.
