A very tired Diana, and an equally weary Wendy arrived at the school just when Miss Todd was getting absolutely desperate about their absence. She had sent Miss Chadwick to Athelton to meet the seven o'clock omnibus, and the teacher had returned to report that they had not come on it. Miss Todd forbore to scold two such limp wrecks, and sent them straight upstairs, with orders for hot baths, bed, and basins of bread-and-milk. Explanations were reserved for next day, and they did not get off scot free by any means. Miss Todd had an aggravatingly mathematical mind. She calculated the time the omnibus left the market-place, the exact moment when she herself started in the trap from the Queen's Hotel, the distance between these two given points, and in how many minutes at the rate of not less than three miles an hour two ordinary walkers should accomplish it. The answer left ten whole minutes to spare, and of that ten minutes of the afternoon she demanded a strict account from Diana and Wendy.
