“Three hours should suffice to gather from the authorities what force they can despatch, and as soon as you have learned this, embark again and sail south. You may reach Madalena in two days. Thus, at the earliest, it must be from six to seven days before you can bring us the news there; if you meet with calms or foul winds you may be well nigh double that time. If at Ostia you can get a faster craft than this, hire it, or take a relay of fresh rowers. I will furnish you with means when I give you the letters.” In less than half an hour Gervaise was on deck again. The boat had returned with the other Italian knights. An ample store of provisions had been placed on board the Sperondra, both for the crew and for the three knights, and, without a minute's delay, these took their places on board, the great sails were hoisted, and the craft glided rapidly away. “The villagers spoke truly as to her speed,” Ralph said, as they looked after her. “Even with this light wind, she is running fully six miles an hour, and as, by the look of the sky, there will be more of it soon, she will make the run to Ostia well within the time we calculated.” Gervaise now questioned the other Italian knights as to what information they had gained. They said the peasants had told them that several strange craft, using both oars and sails, had been noticed passing northwards, and that so strong was the opinion that these were either Algerines or Tunisians that, for the last three or four days, none of the fishing craft had ventured to put to sea. They were able to tell but little as to the bays along the coastline, which they described as very rugged and precipitous. Five or six little streams ran, they knew, down from the mountains. They thought the most likely places for corsairs to rendezvous would be in a deep indentation north of Cape Bellavista, or behind Cape Comino. If not at these places, they might meet in the great bay at whose entrance stands Tavolara Island, and that beyond, there were several deep inlets on the northeastern coast of the Island. Gervaise had a consultation with Ralph. “The first thing is to find out where these corsairs have their meeting place, Ralph; and this must be done without their catching sight of the galley or of the prizes, which some of them would be sure to recognise.” Ralph nodded. “It is a difficult question, Gervaise. Of course, if we had a boat speedy enough to row away from the corsairs it would be easy enough; but with wind and oars they go so fast that no boat could escape them.”
