Under this passageway provision is made for car-ing for the flow of a large brook. Near the ferry, the road location passed directly acrossa loose rock slide. Every attempt to excavate in this fora foundation for the road caused a movement of thewhole mass. The difficulty was finally overcome by pour-ing cement grout over the whole lower part of the slidein sufficient quantity to fill the crevices and make it prac-. .SQIJRKZINC ALdN; THE tically a monolith. After the grout had set, the founda-tion for the road was laid. Wooden forms were used in the construction of thecurbj which was placed in advance of the laying of thepavement base. To give the concrete a color in harmonywith the stone used in the parapets, the forms were plas-tered with a mixture of one-third pound of lampblack■to 94 pounds of cement and 188 pounds of sand just be-fore the concrete for the curbs was placed in them. Six-inch curbs were used, with contraction joints made withtarred paper placed every ten feet, though dummy jointswere used to give the appearance of five-foot concrete for the curbs, which were protected withWainwright steel nosing, was mixed 1:2:4.
