Lutha's only hope lay in united defense of her liberties under the leadership of the one man whom all acknowledged king--Leopold. Very well, Barney Custer, of Beatrice, would be Leopold for a few days, since the real Leopold had proven himself incompetent to meet the emergency.

General Petko, the Serbian minister to Lutha, brought to the audience the memory of a series of unpleasant encounters with the king. Leopold had never exerted himself to hide his pro-Austrian sentiments. Austria was a powerful country --Serbia, a relatively weak neighbor. Leopold, being a royal snob, had courted the favor of the emperor and turned up his nose at Serbia. The general was prepared for a repetition of the veiled affronts that Leopold delighted in according him; but this time he brought with him a reply that for two years he had been living in the hope of some day being able to deliver to the young monarch he so cordially de-spised.

It was an ultimatum from his government--an ultimatum couched in terms from which all diplomatic suavity had been stripped. If Barney Custer, of Beatrice, could have read it he would have smiled, for in plain American it might have been described as announcing to Leopold precisely "where he got off." But Barney did not have the opportunity to read it, since that ultimatum was never delivered.

Barney took the wind all out of it by his first words. "Your excellency may wonder why it is that we have summoned you at such an early hour," he said.

General Petko inclined his head in deferential acknowl-edgment of the truth of the inference.

"It is because we have learned from our chancellor,"continued the American, "that Serbia has mobilized an en-tire army corps upon the Luthanian frontier. Am I correctly informed?"General Petko squared his shoulders and bowed in assent.

At the same time he reached into his breast-pocket for the ultimatum.

"Good!" exclaimed Barney, and then he leaned close to the ear of the Serbian. "How long will it take to move that army corps to Lustadt?"General Petko gasped and returned the ultimatum to his pocket.

"Sire!" he cried, his face lighting with incredulity. "You mean--""I mean," said the American, "that if Serbia will loan Lutha an army corps until the Austrians have evacuated Luthanian territory, Lutha will loan Serbia an army corps until such time as peace is declared between Serbia and Austria. Other than this neither government will incur any obligations to the other.

"We may not need your help, but it will do us no harm to have them well on the way toward Lustadt as quickly as possible. Count Zellerndorf will be here in a few minutes.

We shall, through him, give Austria twenty-four hours to withdraw all her troops beyond our frontiers. The army of Lutha is mobilized before Lustadt. It is not a large army, but with the help of Serbia it should be able to drive the Austrians from the country, provided they do not leave of their own accord."General Petko smiled. So did the American and the chan-cellor. Each knew that Austria would not withdraw her army from Lutha.
