" Many were the last resting-places of toilers of the wheat there on those hills. And surely in the long frontier days, and in the ages before, men innumerable had gone back to the earth from which they had sprung. The dwelling-places of men were beautiful; it was only life that was sad. In this poignant, revealing hour Kurt could not resist human longings and regrets, though he gained incalculable strength from these two graves on the windy slope. It was not for any man to understand to the uttermost the meaning of life. "
