Edward Stratemeyer,
Dave Porter in the Far North
(1908)
“ Away went the mule, as if accustomed to run over the ice all his life. He was a sure-footed creature and took only one or two slides, which amounted to nothing. The boys on the shore saw Dave and mule disappear in the darkness and set up a cry of wonder. "Hi! come back here, Dave!" sang out Roger. "If you are going to ride to the Hall take us with you!" yelled Shadow. "He won't stop till he's tired out," said Henshaw. "And goodness only knows where he'll carry Dave." "Trust Dave to take care of himself," answered the senator's son. ”
