On my return in early April we caught the northeast Trades shortly after turning Cape Palmas, and kept them till close upon Grand Canary. They were a complete contrast with the Harmatan, the firmament looking exceptionally high, and the sun shining hot, while a crisp, steady gale made the 'herds of Proteus' gambol and disport themselves over the long ridges thrown up by the cool plain of bright cerulean. The horizon, when clear, had a pinkish hue, and near coast and islands puffy folds of dazzling white, nearly 5,000 feet high, were based upon dark-grey streaks of cloudland simulating continents and archipelagoes. Within the tropics the heavens appear lower, and we never sight blue or purple water save after a tornado. The normal colour is a dirty, brassy yellow-brown, here and there transparent, but ever unsightly in the extreme. It must depend upon some unexplained atmospheric conditions; and the water-aspect is often at its ugliest when the skies are clearest. I have often seen the same tints when approaching Liverpool. Through the Harmatan-haze we failed to sight Cape Juby, opposite Fuerteventura; and at Santa Cruz I missed Mr. Mackenzie, the energetic flooder of the Sahará. He has, they say, given up this impossibility and opened a _comptoir_: its presence is very unpleasant to the French monopolists, who seem to 'monopole' more every year. South of Juby comes historic Cape Bojador, the 'Gorbellied,' and Cabo Blanco, which is to northern what Cabo Negro is to southern Africa. The sole remarkable events in its life are, firstly, its being named by Ptolemy Granaria Extrema, whence the Canarii peoples south-west of the Moroccan Atlas and our corrupted 'Canaries;' and, secondly, its rediscovery by one Gonçalez Baldeza in 1440.
