Familiarize yourself with the fingering for the G major scale. (The notes are G, A, B, C, D, E, F# and G.) Play the G major scale for two octaves in first position, starting on the open "G" string and ending with the high "G" played with your middle finger on the "E" string. Alternate up-bow and down-bow for each note.
Play the first phrase of the song, starting with B3 and C4, which are played with your middle and ring fingers on the open "G" string. Alternate up-bow and down-bow for each note. The greater than (">") symbol indicates holding a note longer, so you will need to pull the bow more slowly when you see many ">" symbols in a row.
