The School Queens by L.T. Meade

Isabel took great pains arranging Maggie Rowland's bedroom. At the Castle (or Manor) there were always troops of servants for every imaginable thing; but at the rectory the servants were few, and the girls did a good many odds and ends of work themselves. They were expected to dust and keep in perfect order their exceedingly pretty bedrooms, they were further required to make their own beds, and if a young visitor arrived, they were obliged to wait on her and see to her comfort. For the Tristrams had just an income sufficient to cover their expenses, with nothing at all to put by. Mr. Tristram had his two little boys to think of as well as his two girls. His intention was to give his children the best education possible, believing that such a gift was far more valuable to them than mere money. By-and-by, when they were old enough, the girls might earn their own living if they felt so inclined, and each girl might become a specialist in her way.

Molly was exceedingly fond of music, and wished to excel in that particular. Isabel, on the contrary, was anxious to obtain a post as gymnasium teacher with the London County Council. But all these things were for the future. At present the girls were to study, were to acquire knowledge, were to be prepared for that three-fold battle which includes body, soul, and spirit, and which needs triple armor in the fight.
