The harmattan is a sudden dry wind blowing off the coast of Africa, so charged with almost impalpable dust that the sun is obscured. It sucks up all moisture, cracks furniture and earthenware, and prostrates animal nature. The rigging of vessels becomes a dirty brown, and the dust adhering to the blacking cannot be removed.
The tornado lasts for a short time, but is of great force during its continuance.
The northers in the Gulf of Mexico, or off the Heads of Virginia, are not only very heavy gales, but are attended with severe cold. On a December day, off Galveston, the temperature in a calm was at sunset 86°. The norther came on about midnight, and at 8 A.M. the temperature had fallen to 12°, and icicles were hanging from the eaves of the houses. The Tiempo di Vendavales, or southers of Western America, is an opposite, blowing heavily home to the coast. The taifung of China, or typhoon of the Indian seas, is indeed precisely similar to the hurricane of the West Indies.
