It is ninety-seven miles due East from the situation assigned to Dampier's Rocks.

The Cartier also struck upon a shoal hereabouts, and Captain Horsburgh seems to think that there is little doubt of Scott's Reef being the same that Dampier saw, as well as that on which the Cartier struck.
ROWLEY'S SHOALS consist of three separate reefs, the westernmost is the Imperieuse, the middle Clerke's, and the north-easternmost the Mermaid's.
The Imperieuse is ten miles in length from north to south, and its greatest breadth five miles: it is surrounded by very deep water and near the eastern edge, in latitude 17 degrees 35 minutes, and longitude 118 degrees 51 minutes, are some dry rocks.

Clerke's Shoal (south end in latitude 17 degrees 28 minutes, longitude 119 degrees 18 minutes) extends to the north-west, and probably joins the Minstrel's Shoal, which is described below, and, if this is the case, trends North-North-West 1/2 West for seventeen miles.

The south end of Mermaid's Shoal is in 17 degrees 12 minutes South, and 119 degrees 35 minutes East, and extends to the northward for seven miles; but its termination in that direction was not seen.

The edges of all these reefs are steep to; and no bottom was obtained with one hundred and eighty fathoms.
