An inclination in the contrary direction is given to the empty line, sufficient to allow the unloaded waggons to move of themselves, by which means some saving of horse labour is effected. The cost of all the works connected with the dock, including the branch railway, raised platform, permanent rails, dock work, entrance lock and channel, and breastworks along the shore of the river Tees, with the ten coal drops, amounted to the sum of 122,000. These works were designed by Mr. W. Cubitt, V. P., and the Author was the acting or resident engineer. The coal drops are peculiar in their construction and are probably not much known, beyond the district in which they are used; they are distinguished from the drops in common use on the Tyne, by the coal waggons being lowered perpendicularly to the ships' decks, whereas in the latter the waggons are lowered by means of a cradle and vibrating frame, which describes the arc of a circle in its descent. In places where the waggons have to be lowered from a height of 30 feet and upwards to the ships' decks, which is a common circumstance in the Tyne and the Wear, the vibrating frames (originally invented by the late William Chapman of Newcastle) are found well adapted for the purpose; but where the height is limited, or where the railway...
