Death of the Only Daughter of Mr. and Mrs. George Cartwright
Georgie, only daughter of Mr. and Mrs. George Cartwright of Shafer creek, died at the Weiser academy last evening. She was 16 years of age.
The cause of death was bilious fever. The parents were sent for some days ago, but when they reached Boise they were notified that their daughter was so much better that it would not be necessary for them to come. They went home, and yesterday Mrs. Cartwright came back, intending to go to Weiser on last night's train to be with her daughter. Before train time the news came that the sufferer was dead. The remains will be brought back to Boise today.
