Molly sometimes went with her, and the two bright faces brought comfort to many forlorn hearts.

It was an intensely warm day, the first week in July, when a card bearing the silver cross reached her.

"Bad case in third ward. A young girl in the Trask tenement-house, cor. G and Tenth streets. Can you go? Get whatever you need at Reed's, and ask for Bertha Gillette, third floor."

She turned to Molly.

"Is it to-day you have an engagement with the dressmaker?"

"Yes, at three; why?"

Sara read the card, adding,—

"I suppose I'll have to go alone, then. If I should be kept till dark, be sure and have Morton come after me."

"What makes you go, Sara? It's fairly scorching outside!"

"I know, but I must, you see. 'A young girl.' Poor thing! She may have no friends, and be suffering for care. Yes, I must go. I'll wear my thinnest muslin, and take the large umbrella."
