a
     half to four
Traveled until 10.15 and stopped to cook . Rigged a light outrigger for our canoe for night travel , which might be dangerous . We 've got to travel day and night , and take turns steering . Do n't think we got over three and a half to four miles an hour , it may be three miles only , but think we did thirty-five miles to-day . No game and no fish but a few grayling in the morning . We feel a little bit glum . We ca n't tell where we are .
