Mr. Lafount pointed out, in scussing the situation. Except for to broadcasting stations, Con- gress and the commission and the oc- casional appearance of individuals at hearigs, little is heard from the mil- ons of listeners. Yet, Mr. Lafount declared, the in- vestment of the average broadcasting station is less than one-tenth that of its audience. A careful survey of this| phase of the situation, carried on as a listener, has convinced him that the money spent for receiving sets among any body of listeners is at least 10 times as great as that spent by the broadcaster to whom they listen. Un- less the listener can be provided with means whereby he can hear a number dyne will result between stations so controlled. No broadcasting stations have so far been equipped in this way, but it is to be hoped that the method will be practically tried out by sta- tions in the near future.

Tomorrow should be a fairly lucky day, according to astrology, which finds that benefic aspects dominate in the configuration. There should be keener foresight and better judgment under this sway than usually prevails. It is a time to study business con- ditions and to plan wisely for the new year. Women are subject to adverse fn- fluences that may thwart their efforts in public affairs, The evening of tomorrow should be an auspiclous time for entertain- ing, especially at musicals or opera. All the signs presage prosperity for those who follow the artistic profes- sions. It is well to take note of predic- tions concerning the two eclipses of this month, which augur Il for Win- ter weather. Persons whose birth date it is may have many disturbing experiences in the coming vear, which, nevertheless, will be fortunate.

Correspondence of the Associated Press. PARIS.—France has the world record in taxing stock dividends. Pre- mier Poineare, as minister of finance, takes e=gry Ted cent of the dividends on two stocks and more than haif the dividends on a great many others. Taxes on unregistered stocks are so heavy and they vary so much that the Chamber's budget report calls for help for security owner: The two stocks whose owners all their dividends taken by the State are_the light and power company at Nantes and a Moroccan develop. ment firm. Part of this taxation can be avoided by investors who register their securities, but they then sub- ject themselves to other assessments. Of the 245 stocks and bonds listed the budget report four others have 90 per cent or more of the dividends taken by the government. The low- est share the state gets on any of the bonds is 27.4 per cent. The av- erage is a little more than a third. Besides these assessments, the gov- ernment also collects income tax from security owners and a tax from the corporation that often exceeds the amount of the dividend. .

Correspondence of the Associated Press. BERLIN.—The internatlvnalizatiz of the Rhine by the tresty of Ver- sallles has given smugglers new working territory. Ships arriving from Dutch and French ports are the chief culprits, their crews smug- gling into Germany French silk, cos- metics and cognacs, and tobacco and coffes from the Dutch colonles. Dutiable goods are sent in bond across the border for customs inspec- tion at their destination. The smug- glers have contrived to remove the seal during the voyage, extract con- traband articles and replace the seal so ingeniously that it escapes notice. The goods are concealed in the bot- tom of coal bins, sailors’ chests and hidden closets, The English and French secrat service forces are working with the German authorities to trace and root out the smugglers.
