run lengthwise through the masonry, dividing it in three piers, in which the anchor chains are bedded. The total height of the anchorage above high water is at the face 89 feet from where it falls towards the rear with 34 per

cent.

The anchor chains consist of a double set of links, placed over each other. Each set contains ten links, arranged so, that the first two, starting from the anchorplate, are vertical, the next six form a quarter circle and the upper two are horizontal. In each link there are alternately 9 and 10 bars of sizes varying from 3×9 inches for the upper to 3×7 inches for the lower links. The pins also diminish proportionally from 7 to 5 inches in diameter.

Fig. 3 shows in side elevation the upper set of anchorlinks to which the strands are attached. The figures (Fig. 4) written between the bars indicate the order in which the strands are made in succession.

About 10 or 12 feet forward of the

shoe, the two halves of a strand are combined into one, and all strands, before leaving the masonry, are squeezed into a round cable, in which they occupy the following position: (see Fig. 5).

The cables as solid cylinders emerge from the anchorage eight feet below grade line of bridge.

An important part in anchoring the strands is the "shoe" (see Figs. 6 and 7).

It should combine strength with the greatest compactness in order to reduce the width of the chain to a minimum. To resist the squeezing pressure of the strand the shoe is stiffened in front by a connecting piece; but enough length should be given to enable regulation of the strand. The advantages of the shoe are various. It increases the diameter of the curve around which the wires are bent, and it holds the latter between its flanges firmly, preventing any slipping after a wire is once regulated. In removing the strand from its temporary to its final position, the shoe especially is of great advantage, as all connections for hauling are made with the shoe, saving thereby the wires from injury or displacement.

The shoe in its first position rests on the so-called "leg," of which a description may be in place here, as part of the anchorage, though being only of temporary use:

The "leg" is a trough-shaped casting about 12 to 13 feet long. It is held in
