many a useful half-hour discussing cylinders, pistons, valves, and balance-wheels. Jill also came in for her share of care and comfort; the poor little back lay all the easier for the air-cushion Ralph got her, and the weary headaches found relief from the spray atomizer, which softly distilled its scented dew on the hot forehead till she fell asleep. Round the beds of Jack and Jill met and mingled the schoolmates of whom our story treats. Never, probably, did invalids have gayer times than our two, after a week of solitary confinement; for school gossip crept in, games could not be prevented, and Christmas secrets were concocted in those rooms till they were regular conspirators' dens, when they were not little Bedlams.
