As work on the breeding seasons on Ascension developed it became clear that it would be of great advantage to the final assessment of the results if they could he compared with the conditions on St. Helena, an island slightly further from the equator and with certain aspects of seasonal changes well developed. As the existing information was by no means sufficiently precise for this purpose, sanction was given for Dr. Stonehouse and his wife to visit St. Helena for three weeks in November (believed to be a critical season) and two other members of the expedition, Ashmole and Dorward, in April, at end of their work on Ascension. A subsidiary objective will be to examine the subfossil bird remains on St. Helena, not hitherto investigated, from which it is hoped to gain an idea of the, seabird population there in the recent past. The following notes, dated 1 November, were written by Dr. Stonehouse just before he left Ascension for St. Helena.
