noted an extract from the Log book of the Layton: -
Thursday, 4th September at 3pm caught a Cape pigeon, with a label round its neck, thus inscribed: "Symmetry, T. Stevens, bound for the Mauritius and Ceylon, all well on the 2nd September, 1829, South Lat. 30. 0 West Long. 22 deg". It appears remarkable that the Layton spoke the Symmetry off the Cape de Verde about two months before. It appears that the vessels must have kept company within two days sail of each other, or at least within two days of a Cape pigeon flying for two months. What that distance was, we have yet to learn.
