On p. 267 the Author spoke of the lime kunkur for masonry, having been ground in a special mill, while that for concrete had been used just as it came from the mill. He did not see why the mortar for the concrete should be treated worse than the mortar for the brickwork. The essence of hydraulic lime-making was, that the material should be ground to an impalpable powder; because, as with cement, particles that were not so ground were more or less Mr, Robertson, inert. The allowance for skin-friction was of course a very uncertain quantity, but he did not think 5 cwt. per square foot was an unreasonable amount to assume for suoh a deep foundation. With regard to the method of building up the piers under the girders, he might mention a convenient device which had been used in India for that purpose. The girder was supported at the bearings on four legs---wooden legs for small spans and iron legs for large spans. In building the pier, a little chimney was left around the legs; the span was then jacked up, and the chimney was filled with sand, these operations being repeated until the full height had been attained. By that means the trouble entailed by two sets of packing was obviated, and the method was much handier than changing jacks and packing. The cost of the bridge was stated per lineal foot of waterway. Although that was a common system in railway work, the statement was not of much value for purposes of comparison unless the circumstances were precisely similar; and he suggested that for such purposes the area covered by the bridge from the bottom of the foundations to the top of the girders would afford a more reasonable basis.
