A frontier encounter between Greece and Bulgaria has been taken
in hand by the League of Nations. In the old days all the great Powers which had proteges in the Balkans used to hold their hands on their swords so long as a Balkan dispute lasted. Now we can take things calmly because the authority and, up to a point, the efficiency of the League are universally recognized. The frontier affair occurred early last week when a Greek officer and two soldiers were killed. Athens immediately sent a .48-hours' ultimatum to Bulgaria demanding an apology and reparation and punishment of the offenders. No doubt Greece found it very tempting to take a strong line because Bulgaria, as an ex-enemy country, is allowed to maintain only a tiny army. Bulgaria .responded by _appealing to the League. The Council of the League met. in Paris within three days of the dispatch of the appeal—a fine example of alertness which does the Council credit. * *
