The eclipse will take place on June 29, and will be total along a band including Conway, Liverpool, Southport, Lancaster, Ripon, and Durham, the central line running from St. David's Head to a point between Whitby and Hartlepool. It will be the first one visible as such in the British Isles since May 22, 1724, an interval of more than two hundred years. The path just described will be traced out in the morning; so will be the beginning of the track, which will pass on to Scandinavia and Northern Asia. At its fourth subsequent return, that of 1981, the beginning will be displaced sufficiently to miss the British Isles, but at the following return, on August 11, 1999, the middle section of the track will just graze the extreme west of Cornwall. Since there are only twelve families of total eclipses, and each recurs but once in eighteen years, it follows that a total eclipse cannot take place annually. The way in which eclipses do actually occur will be seen from the following list, which covers the eighteen years, and so includes one member of each family. The maximum duration of each is given. Date. Duration. Where Visible. 1922 Sept. 21 mins. 6-1 East Africa, Australia. 1923 Sept. 10 3-6 California, Mexico, Central America. 1925 Jan. 24 2-4 United States. 1926 Jan.
