She had thought of Madame Scarron; she considered her clever; she was so herself, "in that unique style which was peculiar to the Mortemarts," said the Duke of St.Simon; she was fond of conversation; Madame Scarron had a reputation of being rather a blue-stocking; this the king did not like; Madame de Montespan had her way; Madame Scarron took charge of the children secretly and in an isolated house.

She was attentive, careful, sensible.

The king was struck with her devotion to the children intrusted to her.

"She can love," he said; "it would be a pleasure to be loved by her." The confidence of Madame de Montespan went on increasing.

"The person of quality (Madame de Montespan) has no partnership with the person who has a cold (Madame Scarron), for she regards her as the confidential person; the lady who is at the head of all (the queen) does the same; she is, therefore, the soul of this court," writes Madame de Sevigne in 1680.
There were, however, frequent storms; Madame de Montespan was jealous and haughty, and she grew uneasy at the nascent liking she observed in the king for the correct and shrewd judgment, the equable and firm temper, of his children's governess.
