He has a wife and two children. His son is on a mission, and the daughter, a little girl of thirteen, is an invalid. Mrs. Sprague is a model New-England housewife. She has toiled early and late to procure the comforts, and some of the luxuries of life. By the most persevering effort, they at length succeeded in building a beautiful house, and Doctor Sprague's garden is the prettiest in Salt Lake. The family removed to their new residence in the fall of 1862, and had but just furnished it. By the Mormon law of adoption, the property of the adopted child belongs to the father, or is under his control. Dr. Sprague is the adopted son of Brigham Young. His whole property is worth not less than $10,000. Mrs. Emeline Free Young has been very melancholy since Brigham married Amelia. Her health continued to decline until it was thought advisable to remove her from the Lion House, the scene of her joys and sorrow, and situate her more pleasantly. Accordingly one day Brigham called on Dr. Sprague and wife, and coolly told them that he wanted their place for three or four years, for Emeline, until he could build her one. At the end of that time they could have it again, and in the mean time they could live in the house formerly occupied by J. M. Grant, which he would have repaired for their use. The husband and wife were astonished and confounded at this request, and Mrs. Sprague, under the first impulse of her indignation, said "she did not relish the idea of giving up her house to people who read novels every day." "Very well," replied the Prophet, "if you prefer to incur my displeasure rather than to let me have your home, you can do so." With this he left them. The Doctor and his wife began thinking the matter over. It would never do to incur the displeasure of Brother Brigham. He was their father in this world, and their God in the celestial kingdom. Then the Doctor was advancing in years, and should he lose his situation in the Endowment House and Tabernacle, where would be the support for himself and family in his declining years? He had served his adopted father so long and faithfully, should he break with him now? It would never do; so, after many sleepless nights and much anguish of spirit, he made up his mind to make the sacrifice. As to Mrs. Sprague, she cared not for herself, but her poor sick child! She had lived for years almost entirely in the beautiful garden, and how could she leave it now? With frail and faltering step she had wandered amid the flowers and fruit, culling this bright geranium and that lovely rose, plucking this beautiful strawberry, and that luscious bunch of grapes, and by this sweet communion with Nature, the child seemed to receive afresh the life-giving principle. She was now to be torn from her little paradise, by whom, and for what? No wonder if the heart of the mother grew somewhat stony at the reflection.
