[20]I need not say that I refer to national habit. To say this of personal expression would be an obvious and gross libel.

[21]It is curious how all races of mankind, from Ireland to India, Borneo, Japan and Zanzibar, should concur in decorating their holy places in this way. Probably practical convenience is a prosaic part of the explanation.

[22]In spite of its improbabilities the story illustrates well-known and interesting phenomena. Such a sudden rise of the sea as is demanded is quite possible, and the shore level about Jedda, as elsewhere, is extremely low. Though practically tideless the Red Sea is subject to variations of level which cannot be predicted, and which may be as much as three feet vertically. Also objects from the Arabian shore are very commonly carried across the whole sea and stranded on the west side. A year or two ago we learnt that abnormal floods had occurred in Arabia from the number of palm trunks found stranded, and another time, the whole coast, for 100 miles at least, was littered with the bases of palm leaves. These had been left on the ground in some Arabian valley when the leaves were cut for use or sale, and carried into the sea by a flood.

[23]In Egypt Mûled or Mowled means a fair held on a saint’s birthday. On the Red Sea coast a man “makes a mûled” to celebrate any private event, or simply by way of giving an entertainment.

[24]Really dolphin, but this name is also used for a certain fish. The true dolphins, like porpoises, are whales in miniature, air-breathing animals which have become disguised by a fish-like outer shape in accordance with their marine life. Internally every structure is like that of the land mammals from which they are descended, and totally different to that of fishes.

[26]One would not drown them simply because water costs money.

[27]Suakin is populous in winter, the inhabitants going into the hills to escape the summer heat. At my village the reverse is the case.

[28]Flint and steel are sometimes used, but nowadays matches are extremely cheap in all corners of the world.

[29]The leaves and midribs of the date palm are essentials to the people of the desert, nowadays at least, as they use them for all sorts of handicrafts. There are some date palms near Suakin, but their matting is imported.
