Mr. F. Galton, in an address delivered on Thursday to

the 'Geographical section of the British Association, made a practical suggestion of great value. Everybody knows that the maps of the Ordnance Survey are the beat in the world, but they are often very difficult to obtain. The reason is that they are troublesome -to keep, being printed on large paper which creases if it is bent, and that it is not the interest of booksellers and map-dealers to sell them. Mr. Galton therefore recommends that the Survey should issue these maps in quarter-sheets on thin paper, to be sold -folded in pocket size, like the ordinary county maps, at every head post office in the United Kingdom. This would enable any one to -obtain an accurate yet manageable map of the district he lives in -for 6d. He also proposes that the Survey should execute a route map a twenty-fifth of the size of the Ordnance map, or on a scale -of five miles to the inch, a work only to be carried out by Govern- ment, as it only has an accurate knowledge of all alterations of roads, paths, and boundaries. Mr. Gallon has only to prove to Mr. Lowe that the sale of such maps will pay, and he may leave him to fight the booksellers.
