midnight
`` All vegetation has got to have light , and the more it has the harder it will grow . Sun up here is on the job all the time . Reminds me of the year that I started out to be star performer with old John Robinson 's circus back in Injianny . Got up at three a. m. to help feed the animals and hosses , and assist the chef in the cook tent ; waited on table for the canvas men and other nobility from six to nine a. m. , ` doubled in brass ' as the sayin ' goes , with the band , by carryin ' the front end of the bass drum in the gra-a-nd street parade , wore a toga as a Roman senator in the great entree , handled jugglin ' and other apparatus durin ' two performances , and at midnight helped to take down the big top . The other three hours I had to myself . I do n't mean to say that the sun up here in the summer time performs all those gymnastics , but he works the same number of hours and everything up here that wants to live must keep right up with him . Ground is frozen twenty feet deep , and thaws out about eighteen inches in the summer time .
