Here's how I would do it.  There are other ways to position the text.  I've 
left the remaining left-hand fingering to you:

 \version "2.19.15"

    S = \relative c'' {
      \clef treble
        
        \repeat volta 2 {
          \stemUp
          c,16-1 d e f-1 g a b c-1 d e f-1 g a b c-5 b a g f-1 e-3 d c-1 b-4 a 
g f-1 e-3 d
        }
        c4 \mark \markup {\column {"MAJOR SC.                  "  " "  " "} }
        \bar "|."
    }

    B = \relative g {
      \clef bass
        
        \repeat volta 2 {
          \stemDown
          \set fingeringOrientations = #'(down)
          <c,-4>16 d e <f-1> g a b c 
          \change Staff = "up" d e f g a b c b a g f e d c b a 
          \change Staff = "down" g f e d
        }
        c4
        \bar "|."        
    }


global= { \key c \major \tempo \markup { \column {"In Octaves." "C Major" }}  
\time 8/4  }

\score {
        \new PianoStaff <<
           \new Staff = "up"      { \global \S }
           \new Staff = "down" { \global  \B }
        >>
        \layout {
          \context {
                \Staff
                    \remove "Time_signature_engraver"
          }
        }
}
