And taking advantage of the excellent humour in which his potations had put the non-commissioned officer, he filled a large earthen mug with wine, and left the room. The sentinel was leaning against the house-wall, his coat-skirt wrapped round the lock of his musket to protect it from the drizzling rain, and looking as if he would gladly have exchanged his solitary guard for a share in the revels of his comrades, when Paco came out, the cup of wine in his hand, and whistling in a loud key a popular Basque melody. The soldier took the welcome beverage from the muleteer, unsuspicious of any other than a friendly motive on the part of Paco, raised it to his lips, and drank it slowly off, as if to make the pleasure of the draught as long as possible. Thus engaged, he did not observe a man lurking in the shadow of an opposite barn, and who, taking advantage of the sentinel's momentary inattention, and of the position of Paco, who stood so as to mask his movements from the soldier, glided across the street, darted into the house, and, passing unseen and unheard before the open door of the guard-room, nimbly and noiselessly ascended the stairs. The sentinel drained the cup to the last drop, returned it to Paco, gave a deep sigh of satisfaction, and began marching briskly up and down. Paco re-entered the guard room, and placed the cup upon the table. The wine was beginning to make visible inroads on the sobriety of some of the soldiers, and the propriety of putting an end to the debauch occurred to the non-commissioned officer. "Come, boys," cried he, "knock off from drinking, or you'll hardly go through your facings, if required." "Only one glass more, sergeant," cried Perrico. "There is still a pleasant tinkle in the _borracha_." And he shook the large leathern bottle which held the supply of wine. "Only one more, then," said the sergeant, unable to resist the temptation, and holding out his glass. Perrico filled it to the brim, and afterwards did the same for three soldiers who still kept their places at the table, the others having composed themselves to sleep upon the benches round the room. For himself, however, as Paco, who stood behind him, had opportunity of observing, the deserter poured out little or nothing, though he kept the cup at his lips as long as if he were drinking an equal share with his comrades. "Now," said the sergeant, thumping his glass upon the table, "not another drop. And you, Master Perrico, though your father did keep a wine-shop, and your mother carry the brandy-keg, let me advise you to put your head under the fountain, and then lie down and sleep till your turn for sentry. It will come in an hour or two." "And where shall I be posted?" hiccuped Perrico, who, to all appearance, began to feel the effects of the strong Navarrese wine.
