The missionary questions the Italian family, and little Carmelita, thirteen years old, tells her story in some such way as follows:
"Our home was in Naples in the South of Italy. It is so beautiful there! And the sun shines all day long and every day, and we often sing our de
song, "La bella Napoli." We loved our dear sunny Italy so much! But we were very poor, and father heard there is good times in America and
plenty money; so one day he say good-by to us all and come over here. He not find plenty money, and sometimes he very poor, and it was long

"Every week my mother gotta letter, and every time it tell how much money my father saved. Father can't write himself, but he know a boy tha
can; and mother, she get a lady that she work for to read it to her. We not have so many schools in Italy, and when the father and mother were L
