All was quiet as this Highlander wandered backward and forward and it seemed as though his quest would be futile. He then raised his voice and called out: “Sing it again, laddie, sing it again.” The laddie heard and responded and sang on till the searcher found him and carried him back to the base. In due course he returned home wounded but thankful that He had not slumbered who kept him. The higher unity of faith carries further than the discordant notes of mere nationalism. This was illustrated by a writer in the Kansas City _Times_, relating the experience of A Violinist in the Trenches Outside of the dugout, shells whined and machine guns spattered with a staccato of rat-tat-tats. Inside a violin sang and sobbed. The magic of its music made men forget. They forgot the homesickness. They forgot the mud. They forgot the cold. They forgot the ever presence of danger and death. They listened, heads propped up on sand bags and feet wrapped in blankets as they stretched on mattresses of sand bags covering the rough planks of their underground cots. In another dugout, across No Man’s Land on the German side, others were also listening. They heard the strains of Mendelssohn’s “Spring Song,” as sweet and gentle and refreshing as an early summer shower. A strange thing happened. A German picked up a cornet, and floating to the Allies’ dugout came the notes of the horn harmonizing with the violin. CHAPTER VI _Heard Within Prison Walls_ Some of the world’s greatest books were written in prison. Think of the Epistles of St. Paul which came from such secluded confines. _The Pilgrim’s Progress_, which has been translated into more languages than any other book except the Bible, was written by Bunyan in Bedford Jail. Silvio Pellico, an Italian man of letters, recounted his ten years of imprisonment at Spielberg, Austria, and declared that religion was his chief consolation. The singing of St. Paul and Silas during their imprisonment at Philippi had memorable results. There are many other instances of beneficial consequences in connection with these dismal incarcerations. The incidents in this chapter have to do with the influences upon the prisoners themselves and how they were converted to Christ and comforted in their distress. Such transcripts of life under inconceivably trying circumstances give evidence of the power of the Gospel. One of the most remarkable recent books is entitled _A Gentleman in Prison_, giving the experiences of Tokichi Ishii, a converted Japanese criminal, who was executed in due course for murder. The first one tells how Prisoners Sang “The Glory Song”
