It is a well-known fact that a great saving is effected by conducting the exhaust steam of a steam engine through a feed-water heater after performing its function in the cylinder, and thus imparting through this agency a great portion of its heat to the cold water befote it enters the boiler ; and hence its follows that a heater, to be thoroughly effective, should be so constrncted as to present as much surface as possible to the action of the steam, and contact of the supply water. The accompanying engravings show an improved honey-comb heater, whioh aecomplishes this desideratum in a marked de-grae, in whioh Fig. 1 represents a vertical section, Fig. 2 a top view of the ,under section, and Fig. 3 a horizontal section of the same at the dotted line, c d, of Fig. 1. This heater receives its name on account of its resemblance to a honey-comb, and consists of two cylindrical sections containing a series of tubes cast with them, and communicating above and below, with spaces at the center part, where they are secured together by a screw bolt at the upper and lower ends of the heater, the spaces at these last mentioned parts being provided with nozzles for the en. trance and exit of the exhaust steam to and therefrom. These tubes and spaces cause the steam to be displayed and brought in contact with a large area of heating surface, which receives a great portion of its heat, and in turn constantly imprt it to the supply water passing through the several water spaces between and around, and above and below the upright tubes and spaces, as it ascends after entering the lower part of the heater, through thtftorizontalpipe, and before it is discharged from the upper end through the corresponding pipe conducting it to the boiler in a heated state. This multitubular heater differs from all others in use in being formed as described in the claim upon which the patent was issued, "with the tubes, tube sheet or heads, and case, all of one piece of metal, without joints uniting these parts." It is at once cheap, durable and efficient, characteristics which com- , mend it to all owners of steam engines. , Further information may be had by ad-dressing J. C. Hoadley, agent, Lawrence, Mass.

[Fishing rods would scarcely seem to afford much room for invention, but the above is a really valuable addition; it diminishes the friction usually attendant on " running out" and "drawing in," when a reel is employed, by having a 'small pulley at the tip, which adjusts itself to the line, and also prevents the line winding around the rod.] GRINDING MILLS—S. Vascowanl A. Guirancl, of Cincinnati, Ohio : We claim the combined arrangement of the breaking rollers, c' c', with the cylindrical grinder, B, and concave, C C, when the whole is constructed as described, for adjusting the cylinder and concave apart, as described, for grinding.
