the midnight sun
`` The cold weather will be a tonic . It 's a hard job to work the tropics out of one 's blood . But I 'm beginning to shape up now for the Kuskokeem . In the spring , Polly , we start with the dogs , and you 'll see the midnight sun . How your mother would have liked the trip . She was a game one . Forty sleeps with the dogs , and we 'll be shaking out yellow nuggets from the moss-roots .
