eleven o'clock
A night landing was made on a gravelly island to escape as far as possible the many mosquitoes . Tents were not erected but alongside a good fire the blankets were spread on the soft grass beneath the stunted island trees and with mosquito nets wrapped about their heads all slept comfortably enough . Where the Indians slept no one seemed to know . When the boys and their patron turned in as dark came on , at eleven o'clock , the half-breeds were still eating and smoking about their removed camp fire . In this manner , with no accidents , but with daily diversions in the way of shooting , venison now being one of the daily items of food , the voyageurs at last reached the Grand Rapids . From this place , for sixty miles , a tumultuous and almost unnavigable stretch of water reached to the vicinity of Fort McMurray , the end of their journey . The greatest drops in the water and the most menacing perils were encountered at the very beginning of the Rapids , where for half a mile an irregular island of rock divided the stream .
