HOW MAPS ARE MADE.

LONDON'. Sept. o. One of the fpieerest of all the hooks that circulate in Government Departments is to he found at the Ordnance Survey Office at Southampton, where maps are made. At this moment the Ordnance Survey Office is engaged in printing a wonderful array of new maps coverilie; the «hole of the country in scales ranging from one->i\teenth of an inch to the mile to -Jo inches to the square mile. The hook count ins “successive proofs" of the different maps, showing the stages through which a map goes before it finally reaehes Ike public. The first page shows the map printed in black ink in skeleton form, giving nothing hut the names of the different places. The next page is ’devoted to perhaps only two thick red lines—the main roads wending their way through the particular section of the country. The third page will show tin* skeleton map with the main roads printed on it. while the fourth will give four or five minor and proposed roads. The fifth will show those roads on the skeleton. Tiie sixth page is a veritable Chinese puzzle in green—the parks and woods. The next page contains the rivers and streams of the country. Then comes a page of blue daubs representing lakes. Afore daubs, this time in light and dark brown finely tinted, appear in another page; these 'are the low mountains and hills; while the last page but one looks like a pic- I tore of the moon printed in a deep ! sepia colour— the highest points of the j country. ‘ I Each of the series of outlines and j daubs are in their turn printed on the 1 top of the skeleton map, and the finished plate gives the map is it is issued to the public. ]

BAN ON DRUNK DRIVERS. LONDON, Sept. 5. The Danish way with motorists convicted of drunkenness while driving is lo deprive them of their licences for ever. A correspondent points out that in accordance with the Danish law of 1921 the trial of a motorist accused of drunkenness is preceded l>,v an exhaustive medical examination made as soon as possible after his arrest. Jlo is taken into a room for a talk with a police surgeon, who assures him of his (the surgeon’s) neutral position. The examination is no casual test of the driver’s capacity to pronounce the Danish

equivalents of such phrases as “British Constitution.” The surgeon examines the driver according to a system recently devised by the Danish Medico-Legal Council Nothing is left to chance. There are 10 main lines of investigation or tests. It takes about <ls minutes to deal with one average ease. The correspondent continues: The driver may be sober, hut nervous. exasperated or upset by an accident. In the calm atmosphere in which he finds himself this non-alcholic state of confusion usually passes off soon. Again, he may be intoxicated, but an accident and tlic prospect of losing his licence may have temporarily soli crop him. Such artificial sobriety is difficult to maintain for long. As the police surgeon quietly passes from one lost, to another, asking the driver sums in arithmetic and eliciting an account of the events leading up to the accident. the drunken driver is sooner or later sure to betray himsell. Of the first 50 eases medically examined under the new law 9 were discharged as sober, 30 as eases of slight and 11 cases of severe intoxication.
