for some years he was quite alone, with his black servants, in the midst of this wild land. his friends grew anxious, and sent mr. stanley, another great traveller, to look for him. stanley marched for nearly a year before he found livingstone. the old explorer was white and worn with sickness and hardship, and he was overjoyed to clasp once more the hand of a white man, and to hear again the english tongue. but he would not return to england. he said his work was not yet done, and he set out once more on his travels. it was his last journey. one morning his servants found him dead upon his bed. since that time much has been done to make central africa a prosperous land. other white men have followed where livingstone led, and wherever they have settled, the wicked slave-trade has been stopped.
