The concreto should bo tour niches deep and mixed in the following inanner: One mensure Rosendale cement, 2} measures clean sharp sand and 5 measures stone and coarse gravel. ïhis should be well rammed. Bef ore it bas had thneto set the surface should be scratched so as to hold tha top coat. The top coat is ruade as i'ollows: One part portland cerüent and 2 to 2)2' parts clean fine sand. This is spivad oü about 1 % inches deep and theu rammed down toone-half inch. Smooth ofï the top with a trowel. Cover with sand, grass or anything to prevent drying too faM. Keep it covered for at least ten days. When making concrete, be very carefnl not to get too much water. Tlie maas of concrete when ready for use should, with repeated light ramming, show a thin film of moisture on the surface. If properly mixed with water, it will not show a jellylike ïnotion nnder the rammer. For a tar pavement dig out the walk to the depth of four iuches. Thoroughly mix coal tar and coarse graeel and fill in about three inches deep; then roll it down with a heavy roller or else ram it. Thon inake auofcher mixture of fine gravel or sifted coal ashes and tar and spread on a thin coat, cover it with sand and roll or boaf it well. This has been made for about 75 cents por squaro yard.
