ten o'clock in the evening
In a log cabin standing in the center of a small forested moraine four boys of about seventeen were grouped together . The one door and the two windows of the structure were covered with mosquito wire . The hum of insect life came into the room with the monotony of the murmur of the sea . Although it was after ten o'clock in the evening , the sun still rode high above the horizon . A few hundred feet from the outer edge of the ice-cliff , the forested moraine became a `` dead '' glacier . When a glacier advances no longer , but draws back year by year , it is said to be `` dead . '' The live glacier is simply a river of ice pouring down precipices and into gorges and fiords .
