nine o'clock
Going to bed was a matter of some labour at the camp . During the day the beds were piled one on top of another in the one bedroom , the blankets , after hanging in the air for two or three hours , being folded and laid over them . Only in the tent where Mr. and Mrs. Merryweather slept the beds remained stationary all day , the sides of the tent being rolled high , to let the air circulate in every direction . When nine o'clock came , or ten , as the case might be , the order was given , `` Bring out the beds ! '' Straightway the boys made broad their backs , and walked about like long-legged tortoises , distributing mattresses here and there . The three girls slept in the bedroom which opened off the living-room ; the boys and Roger carried their beds into the second tent , or under the trees , or into the boat-house , as fancy suggested , and the wind favoured . Then blankets were unrolled , and the business of bed-making went on merrily .
