all the shapes and figures required, and afterward polishing or not, as required. With this material I make stone gratings and mounts similar to those represented by Figs. 13 and 14, (Fig. 14 showing a variegated face, as described,) and the illuminating concrete gratings represented by Fig. 15, the hydraulic seagliola being employed either for making the entire body of stone or merely as a facing. These hydraulic seagliola stone lights may, when so required, be ground and polished upon the face of the grating.     Fig. 15 represents a concrete light so formed as that the metal bars which form the strength of the grating-- in fact, the grating-- are made to combine with the stone as a part of the general walking and wearing surface. The object of this method of construction is to make a concrete light for hard usage, to be laid at places and subjected to the traffic of heavy merchandise, and the concussion of boxes and packages liable to be thrown down upon it, the metal net-work at the surface of the construction giving durability and strength to the face of the work. This mode of construction also forms a part of my invention.     Figs. 16 and 17 illustrate a method of construction of greater beauty than the preceding, but less capable of withstanding hard usage. This style of work is more adapted for vestibules and halls, and places where mere foot-traffic will pass over it. The mount 16 is formed with an enlarged upper section, k, or head, so that when set in the metal grating the metal bars will not be seen, as shown by Fig. 17. I sometimes cast these mounts around the glasses within the cells of the grating by means of a mold-board or bed placed under the grating, made with supports to hold the glasses in position and produce the flaring or splayed openings aforementioned, this process forming a part of my invention.     I have already stated the purpose of making the apertures or light-holes of concrete gratings flaring-- viz., because of the spaces between the glasses at the surface, made necessary to secure the requisite area of concrete safe-walking foot-surface-- and I have shown one mode of effecting this object; but the same construction, substantially, may be made in either of two other ways-- one by the formation of the under side of each glass as represented by Fig. 18, which is such a glass, and the other by the formation of the iron grating as shown by Fig. 18', which represents a piece of such a grating composed of a congeries of pyramidal shells united at their cases, and strengthened by cross-blades between on the upper or hollow side, the glasses surmounting the pyramidal openings, and the concrete filling occupying the spaces between as shown.     Fig. 18 represents a glass made with a flaring base, l, indicating the polished under face, and l' the upper side of the same, to form a lodgment or rest for the concrete l''. This glass, as may be seen by reference to Fig. 19, is an

octagon at the top; and the construction of glasses in geometrical and design forms for combination with and combining them with cements and concrete to form weather and walking surfaces forms part of my invention of improvements in concrete lights.     It will be seen by Fig. 19 that the effect of the geometrical form of the glass at the surface of the construction is to produce geometrical figures in the concrete filling between the glasses. This is an important matter, as it is an easy mode of obtaining ornamental surfaces of great beauty at comparatively slight cost, the glasses themselves becoming the means of forming the inlaying channels at the surface necessary for the work of ornamentation. The channels, on being filled with concrete l'', particularly if more than one color be employed, give to the face of the grating the appearance of colored inlays of baked clay in the form of tiles, slips, and dots.     Where light in the weather and walking surfaces is not required, or required only partially, my invention consists in producing substantially the constructions aforesaid, by employing, as a substitute for the glasses, colored or other ornamental blocks made from baked clays, or from colored hydraulic cements or concrete, setting the same in the gratings as described, with respect to the glasses, and shaping and combining the same with colored cements, concretes, or tiles, slips, and dots of baked clay, to form ornamental walking and weather surfaces, as aforesaid, a part of my invention consisting in making illuminating, walking, and weather surfaces by combining baked-clay tiles, slips, and dots with the glasses of illuminating-gratings, a further part of my invention consisting in making and using for the aforesaid purposes glasses molded and shaped geometrically to correspond to the stock sizes of the encaustic and colored tiles, slips, and dots existing in the markets.     A further part of my invention consists in making baked-clay gratings and mounts after the manner I have hereinabove described with respect to hydraulic cements and concretes, and combining glasses with the same, for the uses and purposes as aforesaid.     Fig. 20 represents an ornamental cement or concrete slab, made, as represented, with tie-metal strength, or without, according to circumstances, the invention consisting in molding the body of the slab of concrete, so as to leave or form the projecting pieces or blocks A, which in effect correspond to the glasses heretofore described as to these blocks by their position with reference to one another, and by their shape and contour serving to determine the form of the channels between them, and the general surface design produced by filling or inlaying the channels with colored cements or baked clays.     Another part of my invention consists in making hydraulic-cement and concrete constructions substantially the same as the
