Hurricane
a name applied to tropical cyclones occurring especially in the West Indies. They form in the equasweeping course westward and northtorial regions and generally take a long westward, sometimes passing into the most destructive character, but are still known as hurricanes on account of their velocities. The problem of handling ships in hurricanes has been worked out scientifically, one-half of the storm as it moves in circles being the so-called navi- gable half, while the other half is the moves in circles being the so-called navinot only more violent, but in which it running before it into gable half, while the other half is the "dangerous semi-circle" in which the wind is not only more violent, but in which it is not would drive a ship rum the advancing path of the storm. The effect of hurricanes in raising tidal islands and coasts, as in the Galveston, Texas, disasters of 1900 and 1915. During the Spanish-American War of 1898 the United States Weather Bureau organized a special service to protect the American fleet from hurricanes. A chain of observation stations was established around the Caribbean Sea, and this service, now improved by wireless reports IMMIGRATION RESTRICTION from ships, has been of the greatest possible value in protecting the vast amount of shipping bound to and from the Panama Canal. West Indian hurricanes occur chiefly from August to October, and they number on the average about four a IMMIGRATION RESTRICTION LAW, signed by President Harding, May 19, 1921. By this law, which became effective fifteen days after being signed, the number of aliens of any nationality admissible into the United States in the term of any fiscal year up to July 1, 1922, was limited to 3 per cent of the number of foreign-born persons of such nationality included in the U. S. Census of 1910. In accordance with this law, the total number of immigrants admissible in the thirteen months ending June 30, 1922, was fixed at 355,461. The passage of the law was the occasion of a frantic rush in European countries, especially in those of southeastern Europe, to get into the country before the restrictions began, and several nationalities had exceeded their quotas in the first fortnight.
