They both won, too, overcoming fatigue, jet lag and a change of surface.

Nadal, who beat Djokovic in New York to claim his 13th grand slam title, prevailed 6-0 6-0 6-4 over Sergiy Stakhovsky -- Roger Federer's conqueror at Wimbledon -- on his favored clay.

He boosted his Davis Cup record in singles to a near invincible 21-1, with his lone reverse coming in his first outing against Jiri Novak in 2004.

Nadal hadn't played in the competition since 2011, opting to skip proceedings in 2012 even before his season was ruined by a knee injury.

"Today is another victory after a long year and every victory is important," Nadal told the Davis Cup website.

With Fernando Verdasco also winning his match in Madrid against Ukraine, it means Spain is on the verge of retaining its spot in next year's world group following an upset loss to Canada in February.

Nadal is scheduled for the potential doubles clincher Saturday alongside good pal Marc Lopez. If he does take to the court, it would be his first doubles tussle in the Davis Cup in seven years.

"To play with a good friend like Marc will be a special feeling, first time in the Davis Cup," said Nadal.

Canada kept on progressing in the Davis Cup and encountered Djokovic's Serbia in its maiden semifinal Friday.

MR. FURNIVAL AGAIN AT HIS CHAMBERS.

The Christmas doings at The Cleeve were not very gay. There was no visitor there, except Lady Mason, and it was known that she was in trouble. It must not, however, be supposed that she constantly bewailed herself while there, or made her friends miserable by a succession of hysterical tears. By no means. She made an effort to be serene, and the effort was successful--as such efforts usually are. On the morning of Christmas-day they duly attended church, and Lady Mason was seen by all Hamworth sitting in The Cleeve pew. In no way could the baronet's friendship have been shown more plainly than in this, nor could a more significant mark of intimacy have been given;--all which Sir Peregrine well understood. The people of Hamworth had chosen to talk scandal about Lady Mason, but he at any rate would show how little attention he paid to the falsehoods that there were circulated. So he stood by her at the pew door as she entered, with as much deference as though she had been a duchess; and the people of Hamworth, looking on, wondered which would be right, Mr. Dockwrath or Sir Peregrine.

After dinner Sir Peregrine gave a toast. "Lady Mason, we will drink the health of the absent boys. God bless them! I hope they are enjoying themselves."

"God bless them!" said Mrs. Orme, putting her handkerchief to her eyes.

"God bless them both!" said Lady Mason, also putting her handkerchief to her eyes. Then the ladies left the room, and that was the extent of their special festivity. "Robert," said Sir Peregrine immediately afterwards to his butler, "let them have what port wine they want in the servants' hall--within measure." 1. What is the Cleeve?

While these Coronation splendors had been going on, Friedrich, in the Moravian regions, was making experiences of a rather painful kind; his Expedition prospering there far otherwise than he had expected. This winter Expedition to Mahren was one of the first Friedrich had ever undertaken on the Joint-stock Principle; and it proved of a kind rather to disgust him with that method in affairs of war.

A deeply disappointing Expedition. The country hereabouts was in bad posture of defence; nothing between us and Vienna itself, in a manner. Rushing briskly forward, living on the country where needful, on that Iglau Magazine, on one's own Sechelles resources; rushing on, with the Saxons, with the French, emulous on the right hand and the left, a Captain like Friedrich might have gone far; Vienna itself--who knows!--not yet quite beyond the reach of him. Here was a way to check Khevenhuller in his Bavarian Operations, and whirl him back, double-quick, for another object nearer home!--But, alas, neither the Saxons nor the French would rush on, in the least emulous. The Saxons dragged heavily arear; the French Detachment (a poor 5,000 under Polastron, all that a captious Broglio could be persuaded to grant) would not rush at all, but paused on the very frontier of Moravia, Broglio so ordering, and there hung supine, or indeed went home.

Friedrich remonstrated, argued, turned back to encourage; but it was in vain. The Saxon Bastard Princes "lived for days in any Schloss they found comfortable;" complaining always that there was no victual for their Troops; that the Prussians, always ahead, had eaten the country. No end to haggling; and, except on Friedrich's part, no hearty beginning to real business. "If you wish at all to be 'King of Moravia,' what is this!" thinks Friedrich justly. Broglio, too, was unmanageable,--piqued that Valori, not Broglio, had started the thing;--showed himself captious, dark, hysterically effervescent, now over-cautious, and again capable of rushing blindly headlong. 1. what kind of experiences is Friedrich having?
