nine o'clock
They planned a short stay at the Landing and upon reaching camp again before the shortening day was at an end . They carried in the cockpit their Mackinaw jackets and their winter caps . Philip also prepared a cold luncheon to be eaten on the return trip , thus saving time at the Athabasca stop . Early on their outward flight , for a time the red sun made an effort to get through the clouds , but after nine o'clock had wholly disappeared and the temperature began to fall . An almost imperceptible fine dry snow appeared , but it was not enough to interfere with the conduct of the machine . When a landing was finally made at the old place in the bend of the river , although the day was dreary enough , only the chill atmosphere and a few traces of snow gave premonition of possible storm . This time Norman made the visit across the river and he was not gone much over an hour and a half .
