construction, bind the lenses securely in position, and prevent the formation of leaking joints.     It will be understood that I do not desire to limit myself particularly to what are technically known as "channel-bars," or bars of the construction shown, since it is evident that any form of bars having recesses therein to permit the filling in of a body of cement beneath the bases or supporting-flanges of the lenses in the manner described will be within the principle of my invention.     I claim—     1. In a sidewalk-light construction the combination of cupped, grooved, or channeled supporting-bars, lenses having flanges or projecting bases arranged upon said bars with their flanges partially covering said grooves or channels and cement homogeneously filling said grooves or channels, beneath the flanges, and the interstices, between the flanges above said channels and between the treads of the lenses.     2. In a sidewalk-light construction, the combination with lenses having rectangular-bases and, upward extensions therefrom, of parallel supporting-bars disposed below the surface, said bars having longitudinal channels, or recesses therein, the bases of the lenses resting on the parallel supporting-bars and projecting partly over the channels therein without

meeting, and a homogeneous cement filling the channels or recesses of the bars below the bases of the lenses and about and above said bases flush with the top portion of the upward extension from said bases, whereby a strong construction is provided incapable of leakage.     3. In a sidewalk-light construction, the combination with lenses having rectangular bases and upward extensions therefrom, of parallel supporting-bars disposed below the surface, said bars having longitudinal channels or recesses therein, the bases of each individual series of lenses between the supporting-bars abutting against each other and resting upon said bars and projecting over the channels therein without abutting against the bases of the next adjacent series, and a homogeneous cement filling the channels or recesses of the bars below the bases of the lenses and about and above said bases flush with the top portion of the upward extension from said bases, whereby a strong construction is provided incapable of leakage.     In testimony whereof I affix my signature in presence of two witnesses. JAMES MAGNUSEN. Witnesses:     L. M. BULKLEY,     C. C. BULKLEY.
