When the Walrus was stationary, we learned, for the first time, the uses of these unusual preparations.

A pair of the timbers, which were of great solidity and strength, were dropped over the stern, and, sinking beneath the keel, their upper extremities were separated by means of lanyards turned into the eye-bolts.

The lanyards were then brought forward to the bilge of the vessel, where, by the help of tackles, the timbers were rowsed up in such a manner that the links came close to the false keel, and the timbers themselves were laid snug against each side of the ship.

As great care had been taken, by means of marks on the vessel, as well as in forming the skids themselves, the fit was perfect.

No less than five pairs were secured in and near the bilge, and as many more were distributed forwards and aft, according to the shape of the bottom.
